I bought three Lenovo laptops from 2010 to 2011 without proprietary measures on their end. I could upgrade RAM without issue. I gave up on Lenovo this year ever since finding out that they solder one stick of RAM so that if said RAM fails you have to return the system for them to repair it. It also prevents you from upgrading/adding more RAM. I am done with this company and this excellent video supports my stance. Thanks.
@Comrade Of rainbow six seige Yes the older machines were great. The two laps from 2011 are still doing fine one of them being an AMD Turion X2. I do know HP does not solder in their RAM.
Lenovo, HP, acer , asus, etc are pretty much the same, when it comes to low/mid end laptops atleast, they are made by the same ODMs like Compal and Quanta.. i saw motherboards from 3 different laptops from asus, lenovo and HP i think it was and they were pretty much identical.. the difference is mostly in the exterior design, screen, keyboard, mousepad etc

@@ernestmccollum2397 so Louis only recommends Thinkpads that cost as much as Macbooks that are roughly speced equally. Hmm what does this tell us about the whole Apple hate train?
I think Apple takes it a step further and makes the firmware self destruct when read. But Lenovo must not do that if people on eBay are selling them pre-flashed.

I'm not surprised. I bought a top of the line Lenovo laptop for like $1,500+ and it died a year later. I had taken such good care of my expensive tool and hoped it would last many years, which is why I spent more. I also swore I'd never buy another one. I'm sure failures like this were planned for increase of business. I'd never do this to another person. If anything I give more than I'd get in return on most occasions. I can't support a company that takes advantage of people. Thanks for the video verifying my decision a few years back wasn't by mistake.

Sorin, I always enjoy your video's your voice is soothing your mannerisms very country polite, your knowledge unquestionable.. Even I, the 67 year old fella that is just below noob and beginner can understand what you are talking about.. I just started to teach myself electronic last winter.. I have quit working on cars and such because my body can't take it any more so I had to do something.. and with all of these cool new project boards and Arduino's, raspberry pi's and such I thought I would try and join the fun.. I thank God I am already loosing my hair so as I pull it out IO only get about 15 hairs in a hand full.. You do not know how much I appreciate all of your video's your style is so conducive to learning for me that it makes it fun.. one day (if I live long enough) I will be able to follow you completely.. in the mean time.. carry on, be safe and enjoy the heck outta life..
I have old lenovo laptop (cheap and not waterproof). I spilled 3dl of milk all over the keyboard. Few keys stopped working because they clogged, but the computer kept working. It's been working perfectly for 2 years, and when i finally opened it to replace the paste, i saw how it was made. It had a foil in crucial places where it prevented the fluid to go to any crucial parts. I liked that design and I think it is a very good design. Laptop has been working for 7+ years now, no problem. (Lenovo Ideapad 100).

Still using a 2011 lenovo t520, I think they still used the molds and hw designs from the IBM days then, it's very solidly built and hasn't failed me once. But good on you to call Lenovo out on this, I agree this is unacceptable and highly suspicious design. Input protection on pins is a given, there's really no excuse. Either the zener variant you showed or 2 upward facing diodes from gnd to positive. Must be a case of design by gunpoint!

One thing I like about this laptop design is how easy it is to access the CPU fan. One can clean it more often and its easy to replace in case it goes dead or start making a weird noise. In most laptops, you have to remove the motherboard and everything just to access that fan.
hamza ouhammi I have my Lenovo thinkpad for five years the battery last for six hours in the beginning. The last two yrs it last for about 3.5 hours. We have a lot of load shedding in South Africa.
Just to clarify, will this issue occur due to power surge? If so will a surge protector help to overcome this issue? My legion y540 now has this issue and I am now looking for measures to prevent this from happening.
Legions are known to have defective jacks and if the jack breaks, then it can be repaired. I believe you have a broken DC jack, so I would recommend getting that fixed.
Thinkpad, X, and P series are very good laptops. In fact, one of the best on the market as it comes to quality and durability. Saying all lenovo are bad is a bit of an exaggeration. All manufactures are guilty of design failure in their low end products. Cheap, critical design failure, uneconomical to repair, buy new. That's the world we live in and consumer electronics companies business model now days.This laptop is cheap budget lenovo model. This is the case with any budget laptop brand. Apple is even worst, because their high end expensive line is design to fail! You don't want to buy cheapest laptop from any manufacturer. You'er better off buying second hand mid tier model.
Yes, it's nonsense. I have a second hand X230 from about 2012 bought a few years ago for $200 with extra RAM, SSD and added an mSATA. No issues, great keyboard. I also have an X1 Extreme (which was not cheap!) for about a year I use daily for work on the road. Also no issues.
@Stale NFS I have an HP from ten years ago and it works great even after spilling crap on it and using it outside in the summer, Results may vary I guess.
Sad, I will make sure to spread these sad news like Sorin so that no one gets scammed like that. Mr. Sorin you have an amazing attitude for repairing and the right to repair. Have a lovely day, greetings from Montreal, Canada!
If you search internet you see. Many agree ThinkPad is one of the best laptop out there. I have one myself. Very good design and simply to expand/fix. I replace Keyboard in 2min
@@kotaimre1018 hello, I have cheap thinkpad 11e chromebook, and charging port was different. Middle pin have additional plastic housing around. Maby thinkpad was better, or maby lenovo fix charging port already.
I had a lenovo android tablet for the home. different family members had different separate user accounts on the same tablet. One day an update deleted the multi account function and wiped all the data from all the non main accounts, no warning no nothing. On top of that LOWERED the resolution of the screen! So the hardware is higher resolution but the software will only run on low!!! And there is no way to return to the original software version.
Thank you for the warning, and mentioning the eBay seller of the ITE chip. I have a dead, no power & no charge, Lenovo Ideapad G50-45, and I was aghast when I heard the 'beep' for the continuity check on the DC-in middle pin and the corresponding pin on its ITE8586E super I/O chip. Lenovo should do free lifetime repairs for all the affected laptops that have this disgraceful "self destruct" design flaw.
My same model suddenly stop working and unable to turn on and i was told that mother board died so I bought Dell. Now I know what happened to my Lenovo

True, Lenovo picked up many bad practices from Apple but their over-large range includes entry-level machines and the G50-80 is one such. It is not a ThinkPad. Although ThinkPad quality has declined since the fad for slimline took hold the buyer should properly evaluate specs, layout and price. A refurbished 'proper' ThinkPad pre the awful mess that was the T440 should last a demanding user many years and can be upgraded. The pseudo-USB shaped connector was inferior to the barrel type from the start and should be discontinued. People who have pointed out that most Apple products are flimsy and hard to repair despite the enormously inflated prices and lousy official service are right. However, the bad power protection on the G50-80 is on a cheap machine. Sorin might have different thoughts on other Lenovo products but I hope that he has shamed the greedy designers with his cogent points. It is also great to see a true expert at work.
To be fair, Lenovo has many series of production, the cheap ones and the heavy duty. I have been using Lenovo X series for more than 12 years now, I have 4 of them in line, and they are all still working perfectly (except for some batteries)
Here's another one: Dell puts a charging clock in the battery. After the warranty is up, it prevents charging. So they don't get caught its based on number of recharges not the calendar.
I own many Lenovo laptops(>8) of various models except G50-80, every one of them is very good to excellent. Maybe only the G50-80 model is not well designed other models are very good to excellent. I am typing from one.
I have a lenovo laptop as well and i can say they are good. Mine is six years old and still going strong. I want to replace it but the damn thing is immortal.
copy pasting my own comment cause the point is still the same. His point is not giving a fair review, but bashing Lenovo products. I myself had multiple laptops of multiple brands, and those i never had problems with are the asus and the lenovos, unlike the countless problems i got with HPs after just 3 years of usage. Many laptops dont have such design, he's bashing the whole line in name of the fews that do. Other than that i would never send a repair to this guy, laptop has been handled without care, the whole disassembly was just homeboy stlyle. There's a difference between repairing computers and knowing how to repairing computers.
Thinkpads are great machines but I have experience with a U530 where the hinge cracks (common problem). This forces you to buy a new machine just because some cheaply made part decides to fail.
@@raffaele148 thank you for your comment. This is exactly how I feel. You can't bash the company for an engineering compromise made to one product. I have been repairing all types electronics for the last 30 years and have 3 lenovo products. I only recommend lenovo of I'm forced to recommend anything. And it's so true. I wouldn't send my stuff to this guy even though he knows his stuff. He's too heavy-handed and seems to get distracted easily.
I found your channel after my $1200 Lenovo bit it after only 2 years. Decided after watching a few videos, I wasn't going to be able to fix it, however, watched a video of you working on an ASUS gaming laptop, you pointed out how well it was made, so I picked up a used one. Very happy so far. Lenovo is garbage---I'm only glad that at least my data on the SSD was still recoverable. Great channel, you're a fantastic teacher!
ppl who say " i have a lenovo its its gr8" clearly is missing the point. The point of this video is that if it gets broken, you cannot repair it. And that is anti consumer, and you should not apluaud it.
i thought these super io are already programmed...thas why for me i tried to replace 1 of the lenovo g50...the board was working perfect but the keyboard was not reading....now have realized that they must be programmed to the same model👍👍
@@robertoruiz7069 Imagine you drive a car at 20mph and a wheel falls off. Is it the manufacturers fault if the entire cabin falls apart during the ensuing crash? The manufacturer is supposed to build some sturdiness into it's product. Off course you should expect the charging port to get destroyed. The charging port is the third most physically stressed part of the laptop after the keyboard and the hinges (by normal use, I'm not talking smashing screens). CHARGING PORTS WILL GET DESTROYED. Manufacturers know that. If the SuperIO was not protected against the shorting in the charging port SOMEONE INTENTIONALLY DID THAT.
I have the predecessor, the g50-70. On it's charging port the sensor- and the +-rail are seperated by a plastic housing. Looks like they removed it intentionally on later models. That is how you improve your design!
is it posible to just directly modify the charging port and add a resistor and zener diode on the line of the middle pin before going to the track connecting to the super io of the charging port for protection?
Many years ago I worked for HP on their minicomputers. My guess is that this was NOT an intentional design flaw to frustrate customers. That would take too much thought and work. Mistakes like this are usually the result of sloppiness, being rushed, not putting a high priority on products being resilient. An engineer might have tried to bring this issue up in a meeting, but be voted down because the schedule was tight. Kudos to Sorin (and to Rossman) for making knowledgeable criticism of bad design. It is great ammunitiion for engineers inside Lenovo or Apple to tell the rest of the team: "Hey, if we let this sloppy design go by, we'll get roasted online. Let's take a little more time and do it right!"
Stuff like this still shouldn't happen. It is 2 cents in parts and can be done super easily in the schematic and layout. Esd protection should always be there on any pin going outside. This is just a wrong design philosophy / quality standard
@@unbekannternutzer8506 , I don't disagree. I'm just describing how it probably happened, given my experience on projects in a large corporation. The area I worked in was higher end, and people were more careful. Still things like this occurred. There's tremendous pressure to ship product.
One bit I do not understand. What does the middle pin do? It goes direct to the super I/O. But the super I/O needs 3.3v. What is it doing on the charger socket? Are they providing a separate 3.3v from the charger? If it is just a nasty trap, why not make it safer now, by disconnecting the middle pin?
I have the same laptop - G50-80 and was surprised that the screws were still on in the body. All but 2 of the screws have come out on my laptop. Not by rough usage, just everyday handling. The hinge cover broke off and the lock for the screen bezel only work half the time. The 12V power port broke off/dislodged and it is a pain every time I have to plug in the charger, so most times I just let it be. The HDD that came with the laptop died the week after the warranty expired (& even though the HDD should still be covered by manufacturers warranty, Lenovo asks me to take it up with WDD/Toshiba). The battery too died 17 months after I bought it and the after market battery I bought doesn't charge beyond 50% now. The original charger works but the jack was frayed & cables came out. I didn't want a short so I simply got a new charger. But it hasn't given me other problems. like fan or CPU/RAM/Mainboard issues.

good night I would like to thank you for the very useful lessons you have given and important tips you have given, especially in my case repairing laptops, the dislikes you have probably had been given by your competitors, I hope you will continue to teach why laptop breakdowns can be so many and haven't taught everything yet :)
Agree with you. That is .. Intended. Why?I clearly understand why buying a product from a company that refuses to protect such a sensitive component like the super IO. Nice video.
Enjoyed the video. But my work experience suggests this sort of built-in risk is probably mostly an error. From work I found like mistakes in electronics in missiles and radar designs for defense systems. Also errors that can cause total failure. In heavy equipment designed in risks that could result in killing operators. Much design is pushed to meet deadlines that contribute to the risk, particularly as product competition drives decisions, and understanding risk often can be not analysed before failures. Surprisingly the management of companies do not always acquiesce to fixing these until a history of damage specific to the particular product becomes undeniable even when shown like problems in other products. Caveat emptor cautions that the buyer might over pay, but in these cases the product may cause a catastrophe. Consider the Chenobyl reactor as a particularly extreme example of poor judgement rather than intentional miscredence.
Facts are objective, opinions are subjective. Same for everything, bad practices, scam, exist and have a long life because some people are stupid and even if you teach them the scam point, they stay stupid and live in a kind of deny mind position. For example, Apple sale expensive hardware and software and spy there customer through back doors, they also lock them with a jail commercial system than they have to buy special plugs, special software for anything, at expensive price. What ever some nice people demonstrate about these crooks practice they do, some customer hate who ? The crooks ? No, they hate the people who show them the objective true about the scam. Why ? Because they are stupid and yes, crooks make money (a lot) with stupid people. And there is so much...
I own an oldschool x200 and use some brand-new Thinkpad (from employer). Even though both are thinkpads the difference is night and day. That old x200 with it's Core 2 Duo is still soldiering on despite all odds (with Windows 10 and Visual Studio running... well, at a respectable speed) while the new one is literally falling apart without any reason. So yeah, T series an older W and X are good newer ones not all the time.
IDK Sorin my son has a 5 year old Lenovo g50-45 and it still runs great Amd A6 and a Programmer is very simple to use for someone like you who can solder so easily you can restore so many motherboard bios, vbios, Super I.O. for a customer ..I know if I could solder like you I would because some users really love their laptop and charge them a fare price at $150 for the job still cheaper than a new laptop and you can save their stuff. You are right about manufacturers do some sloppy designs on purpose to make things fail so you can buy a new one.
Around 23:10 - putting the magic smoke back into the chip. Thanks for a very educational video, I learned quite a bit including SMT desoldering and use of zener/resistor to protect the pin, though as you point out there should be no need for a consumer to do this and the manufacturer has clearly designed the product to fail.
@@ernestmccollum2397 I have that same model laptop, it is a cheaper variant, yes, but I'm not seeing the issue here, it's solidly built and stands up to "premium" computers that cost twice as much...
Nice video as usual Sorin. I find the quality of Lenovos to be pretty patchy, have used them as corporate laptops for many years. X250 - brilliant laptop, absolutely no problems for 3 years. T470 - complete rubbish, NVME and Motherboard failure within 12 months - along with other random failures. T450 (a little older) - proving quite robust after a year. Replaced T470, random failings again. Compare that to my Dell XPS M1330.... still going strong with a constant flogging after 12 years - and very upgrade-able. I suspect the complete laptop designs have gone backward in quality, rolling in very poor thermals with gotchas such as this super i/o cooker...
This is a tough call. The center pin barrier of the notebook power jack is broken and the pin is smashed. Normally there's a fairly thick hard plastic insulating barrier around that pin. So technically the user attempted to use the adapter with a broken power jack. Whether the user was rough on it or the casting was faulty, we don't know. The center pin is an adapter ID signal identifier to the notebook to identify the use of the proper AC adapter due to power conservation constraints (and of course using a rectangular design in place of the common coaxial type jack prevented users from mistakenly plugging in any old adapter "willy-nilly" into the unit and destroying it). The adapter ID signal uses a very small range of resistors (45W -> 120 ohms, 65W -> 280Ω, 90W->550Ω, 135W->1kΩ and 170W->1.9kΩ), probably through a voltage divider network so that the it8586 chip can measure it with the GPIO pin in the ADC mode. With the it8586 chip operating at VCC=3V this only provides for a tight and fairly critical measurement range. It's tough to say based on that small range if a 3V (or lower) zener could really accomplish anything here without throwing off the voltage divider measurement based on the required series resistor, the zener's dynamic internal reverse resistance, the negative temperature coefficient effect for zeners under 5V and also the very soft (almost useless) knee curve of a 3V or lower rated zener. Again tough call - at some point you have to assume that the center pin barrier will hold up to constant insertions and removals .. but this is not military class stuff, if so, the price point would start to leave the consumer range .. you have to draw the line somewhere.
@@electronicsrepairschool Hard to say if it is or isn't. Someone below commented "DELL is guilty of this same practice", so maybe it is. I'm not privy nor in possession of reliability or failure mode field data for these company's products so I couldn't say if this exact type of failure is commonplace. One thing for sure, a quick survey of ebay shows that power jack replacements for all brands seem to always be in high demand - no doubt a common failure point. These manufacturers are always holding financial liability in the form of product warranty coverage for at least the first year or so - sometimes longer -- so they've got to make sure that the unit can survive the initial warranty coverage period. That unit is over 4 years old and seems to have made it through. None of them actually manufacture the power jack itself - those are sourced from connector specialty companies - hopefully they know what they're doing. All that said, you have some of the best repair videos on all of youtube - please keep up the great work! :-)
@electronics repair school: Hi, Some keys of my Lenovo X270 keyboard were not working so I've decided to replace it myself. I was very cautious and followed the service manual and best practices and could remove the faulty keyboard successfully. I plugged back all the ribbon cables and everything into its place. The issue is now the laptop turns ON (green light, the fan also turns, there is no beep unless I remove RAM memory) but the screen remains black. I've tried to connect it to an external monitor (and keyboard/mouse) but it didn't work. I've removed the CMOS battery for a while and put it back on but it didn't help. I have a big issue because when I wanted to connect the SSD drive to another laptop to access at least my data and back it up, it asks for BitLocker key which I never set (only had Windows session password) and I believe it is security/tamper protection from the old laptop. Could you please tell me what can be the issue? The GPU? Thanks a lot for your help.
I have 3 Lenovo laptops in my household, just repaired another one for a friend who spilled coffee on the keyboard and they all work great. My Z560 that I bought in 2009 has an I5 M480 duel core hyperthread (4 logical processors) 8 gig 1066Mhz ram and a Sata II SSD has a round standard power plug. My daughters has the square plug, I don't know the model. That one looks pretty beat up. Mine @ 10 years old is in mint condition, not one scratch on it anywhere, I did recently have to replace the keyboard on it too because some of the keys stopped working even though nothing has ever been spilled on it???
the keyboard data cable often rot and get scratched easily when re-inserted into the keyboard port on the laptop. It is bad design, laptop manufacturer use port that bite & scratch keyboard's cable copper and damage it.

I thank God I am already loosing my hair so as I pull it out IO only get about 15 hairs in a hand full.. You do not know how much I appreciate all of your video's your style is so conducive to learning for me that it makes it fun.. one day (if I live long enough) I will be able to follow you completely.. in the mean time.. carry on, be safe and enjoy the heck outta life..
I have old lenovo laptop (cheap and not waterproof). I spilled 3dl of milk all over the keyboard. Few keys stopped working because they clogged, but the computer kept working. It's been working perfectly for 2 years, and when i finally opened it to replace the paste, i saw how it was made. It had a foil in crucial places where it prevented the fluid to go to any crucial parts. I liked that design and I think it is a very good design. Laptop has been working for 7+ years now, no problem. (Lenovo Ideapad 100).

Can you add a resistor and zener diode to the charging port to fix lenovo's bad design?
It's possible, but quite hard to cram these components on such a board. That would not be reliable though.
Of course you can.

Still using a 2011 lenovo t520, I think they still used the molds and hw designs from the IBM days then, it's very solidly built and hasn't failed me once. But good on you to call Lenovo out on this, I agree this is unacceptable and highly suspicious design. Input protection on pins is a given, there's really no excuse. Either the zener variant you showed or 2 upward facing diodes from gnd to positive. Must be a case of design by gunpoint!

One thing I like about this laptop design is how easy it is to access the CPU fan. One can clean it more often and its easy to replace in case it goes dead or start making a weird noise. In most laptops, you have to remove the motherboard and everything just to access that fan.

Thinkpad, X, and P series are very good laptops. In fact, one of the best on the market as it comes to quality and durability. Saying all lenovo are bad is a bit of an exaggeration. All manufactures are guilty of design failure in their low end products. Cheap, critical design failure, uneconomical to repair, buy new. That's the world we live in and consumer electronics companies business model now days.This laptop is cheap budget lenovo model. This is the case with any budget laptop brand. Apple is even worst, because their high end expensive line is design to fail! You don't want to buy cheapest laptop from any manufacturer. You'er better off buying second hand mid tier model.
Yes, it's nonsense. I have a second hand X230 from about 2012 bought a few years ago for $200 with extra RAM, SSD and added an mSATA. No issues, great keyboard. I also have an X1 Extreme (which was not cheap!) for about a year I use daily for work on the road. Also no issues.

It wasn't always like that. I still have a G565 in daily use. It was somewhere around 400$ back in 2010-2011 and still works perfectly fine.

Not just lenevo ,Lenovo learned from Apple non repairable technologies how to make more money making all your products non repairable !
True, Lenovo picked up many bad practices from Apple but their over-large range includes entry-level machines and the G50-80 is one such. It is not a ThinkPad. Although ThinkPad quality has declined since the fad for slimline took hold the buyer should properly evaluate specs, layout and price. A refurbished 'proper' ThinkPad pre the awful mess that was the T440 should last a demanding user many years and can be upgraded. The pseudo-USB shaped connector was inferior to the barrel type from the start and should be discontinued.
People who have pointed out that most Apple products are flimsy and hard to repair despite the enormously inflated prices and lousy official service are right. However, the bad power protection on the G50-80 is on a cheap machine. Sorin might have different thoughts on other Lenovo products but I hope that he has shamed the greedy designers with his cogent points. It is also great to see a true expert at work.

I own many Lenovo laptops(>8) of various models except G50-80, every one of them is very good to excellent. Maybe only the G50-80 model is not well designed other models are very good to excellent. I am typing from one.
Same feeling, my friend's Lenovos and my own t440p never had any similar problem lol
I have a lenovo laptop as well and i can say they are good. Mine is six years old and still going strong. I want to replace it but the damn thing is immortal.
copy pasting my own comment cause the point is still the same.
His point is not giving a fair review, but bashing Lenovo products. I myself had multiple laptops of multiple brands, and those i never had problems with are the asus and the lenovos, unlike the countless problems i got with HPs after just 3 years of usage. Many laptops dont have such design, he's bashing the whole line in name of the fews that do.
Other than that i would never send a repair to this guy, laptop has been handled without care, the whole disassembly was just homeboy stlyle. There's a difference between repairing computers and knowing how to repairing computers.
Thinkpads are great machines but I have experience with a U530 where the hinge cracks (common problem). This forces you to buy a new machine just because some cheaply made part decides to fail.

I found your channel after my $1200 Lenovo bit it after only 2 years.

Very happy so far. Lenovo is garbage---I'm only glad that at least my data on the SSD was still recoverable. Great channel, you're a fantastic teacher!
Lenovo quality after 2016 is certainly not the same.
ppl who say " i have a lenovo its its gr8" clearly is missing the point. The point of this video is that if it gets broken, you cannot repair it. And that is anti consumer, and you should not apluaud it.

@@robertoruiz7069 Imagine you drive a car at 20mph and a wheel falls off. Is it the manufacturers fault if the entire cabin falls apart during the ensuing crash? The manufacturer is supposed to build some sturdiness into it's product. Off course you should expect the charging port to get destroyed. The charging port is the third most physically stressed part of the laptop after the keyboard and the hinges (by normal use, I'm not talking smashing screens). CHARGING PORTS WILL GET DESTROYED. Manufacturers know that. If the SuperIO was not protected against the shorting in the charging port SOMEONE INTENTIONALLY DID THAT.
My Lenovo never have any issue, but it,s fun to watch your video.

is it posible to just directly modify the charging port and add a resistor and zener diode on the line of the middle pin before going to the track connecting to the super io of the charging port for protection?
OMG now i know why.... Thank You Sir!
Thank you so much i had same exact problem and was almost to buy new motherboard....and i find you...thanks u saved me a lot of money
Many years ago I worked for HP on their minicomputers.
My guess is that this was NOT an intentional design flaw to frustrate customers. That would take too much thought and work.
Mistakes like this are usually the result of sloppiness, being rushed, not putting a high priority on products being resilient. An engineer might have tried to bring this issue up in a meeting, but be voted down because the schedule was tight.
Kudos to Sorin (and to Rossman) for making knowledgeable criticism of bad design. It is great ammunitiion for engineers inside Lenovo or Apple to tell the rest of the team: "Hey, if we let this sloppy design go by, we'll get roasted online. Let's take a little more time and do it right!"
Stuff like this still shouldn't happen. It is 2 cents in parts and can be done super easily in the schematic and layout. Esd protection should always be there on any pin going outside. This is just a wrong design philosophy / quality standard
@@unbekannternutzer8506 , I don't disagree. I'm just describing how it probably happened, given my experience on projects in a large corporation. The area I worked in was higher end, and people were more careful. Still things like this occurred. There's tremendous pressure to ship product.

Did you reprogram it yourself?
I need to do the same. If you can , please tell the sources you've followed.
TIA.
One bit I do not understand. What does the middle pin do? It goes direct to the super I/O. But the super I/O needs 3.3v. What is it doing on the charger socket? Are they providing a separate 3.3v from the charger? If it is just a nasty trap, why not make it safer now, by disconnecting the middle pin?
What do u expect from an old laptop , maybe they changed their designs in the new ones
It might be old. But you'd expect it to be designed by an adult. Not a 13 year old.
I have the same laptop - G50-80 and was surprised that the screws were still on in the body. All but 2 of the screws have come out on my laptop. Not by rough usage, just everyday handling. The hinge cover broke off and the lock for the screen bezel only work half the time. The 12V power port broke off/dislodged and it is a pain every time I have to plug in the charger, so most times I just let it be. The HDD that came with the laptop died the week after the warranty expired (& even though the HDD should still be covered by manufacturers warranty, Lenovo asks me to take it up with WDD/Toshiba). The battery too died 17 months after I bought it and the after market battery I bought doesn't charge beyond 50% now. The original charger works but the jack was frayed & cables came out. I didn't want a short so I simply got a new charger. But it hasn't given me other problems. like fan or CPU/RAM/Mainboard issues.

I would like to thank you for the very useful lessons you have given and important tips you have given, especially in my case repairing laptops, the dislikes you have probably had been given by your competitors, I hope you will continue to teach why laptop breakdowns can be so many and haven't taught everything yet :)
Agree with you. That is .. Intended. Why?I clearly understand why buying a product from a company that refuses to protect such a sensitive component like the super IO. Nice video.
Enjoyed the video. But my work experience suggests this sort of built-in risk is probably mostly an error. From work I found like mistakes in electronics in missiles and radar designs for defense systems. Also errors that can cause total failure. In heavy equipment designed in risks that could result in killing operators. Much design is pushed to meet deadlines that contribute to the risk, particularly as product competition drives decisions, and understanding risk often can be not analysed before failures.
Surprisingly the management of companies do not always acquiesce to fixing these until a history of damage specific to the particular product becomes undeniable even when shown like problems in other products. Caveat emptor cautions that the buyer might over pay, but in these cases the product may cause a catastrophe. Consider the Chenobyl reactor as a particularly extreme example of poor judgement rather than intentional miscredence.
Thank you so much for the info

What ever some nice people demonstrate about these crooks practice they do, some customer hate who ? The crooks ? No, they hate the people who show them the objective true about the scam.

Nice video as usual Sorin. I find the quality of Lenovos to be pretty patchy, have used them as corporate laptops for many years. X250 - brilliant laptop, absolutely no problems for 3 years. T470 - complete rubbish, NVME and Motherboard failure within 12 months - along with other random failures. T450 (a little older) - proving quite robust after a year. Replaced T470, random failings again.
Compare that to my Dell XPS M1330.... still going strong with a constant flogging after 12 years - and very upgrade-able. I suspect the complete laptop designs have gone backward in quality, rolling in very poor thermals with gotchas such as this super i/o cooker...
My Lenovo laptop after 2 years of use: **Random BSoD**
it may have a bad stick of ram.
This is a tough call. The center pin barrier of the notebook power jack is broken and the pin is smashed. Normally there's a fairly thick hard plastic insulating barrier around that pin. So technically the user attempted to use the adapter with a broken power jack. Whether the user was rough on it or the casting was faulty, we don't know. The center pin is an adapter ID signal identifier to the notebook to identify the use of the proper AC adapter due to power conservation constraints (and of course using a rectangular design in place of the common coaxial type jack prevented users from mistakenly plugging in any old adapter "willy-nilly" into the unit and destroying it). The adapter ID signal uses a very small range of resistors (45W -> 120 ohms, 65W -> 280Ω, 90W->550Ω, 135W->1kΩ and 170W->1.9kΩ), probably through a voltage divider network so that the it8586 chip can measure it with the GPIO pin in the ADC mode. With the it8586 chip operating at VCC=3V this only provides for a tight and fairly critical measurement range. It's tough to say based on that small range if a 3V (or lower) zener could really accomplish anything here without throwing off the voltage divider measurement based on the required series resistor, the zener's dynamic internal reverse resistance, the negative temperature coefficient effect for zeners under 5V and also the very soft (almost useless) knee curve of a 3V or lower rated zener. Again tough call - at some point you have to assume that the center pin barrier will hold up to constant insertions and removals .. but this is not military class stuff, if so, the price point would start to leave the consumer range .. you have to draw the line somewhere.

I'm not privy nor in possession of reliability or failure mode field data for these company's products so I couldn't say if this exact type of failure is commonplace. One thing for sure, a quick survey of ebay shows that power jack replacements for all brands seem to always be in high demand - no doubt a common failure point. These manufacturers are always holding financial liability in the form of product warranty coverage for at least the first year or so - sometimes longer -- so they've got to make sure that the unit can survive the initial warranty coverage period. That unit is over 4 years old and seems to have made it through. None of them actually manufacture the power jack itself - those are sourced from connector specialty companies - hopefully they know what they're doing. All that said, you have some of the best repair videos on all of youtube - please keep up the great work! :-)

@electronics repair school: Hi,
Some keys of my Lenovo X270 keyboard were not working so I've decided to replace it myself.
I was very cautious and followed the service manual and best practices and could remove the faulty keyboard successfully.
I plugged back all the ribbon cables and everything into its place.
The issue is now the laptop turns ON (green light, the fan also turns, there is no beep unless I remove RAM memory) but the screen remains black.
I've tried to connect it to an external monitor (and keyboard/mouse) but it didn't work.
I've removed the CMOS battery for a while and put it back on but it didn't help.
I have a big issue because when I wanted to connect the SSD drive to another laptop to access at least my data and back it up, it asks for BitLocker key which I never set (only had Windows session password) and I believe it is security/tamper protection from the old laptop.
Could you please tell me what can be the issue? The GPU?
Thanks a lot for your help.
i have lenovo laptop and im scared after seeing :(
Be careful when you plug in your charger and you'll be ok.
True
@@DariusIC like it's okay ok ?
Not all Lenovo is designed like that. Especially the ThinkPad
@@emanuelmilani7976 I dont have the thinkpad i have a lenovo 300
I have the same thing and do u know when I plugged the charger it caused huge sparks and then I thought the charger went bad
Oh this is HP, different job.
Hahahaha!
Sorin is so funny.

I have 3 Lenovo laptops in my household, just repaired another one for a friend who spilled coffee on the keyboard and they all work great. My Z560 that I bought in 2009 has an I5 M480 duel core hyperthread (4 logical processors) 8 gig 1066Mhz ram and a Sata II SSD has a round standard power plug. My daughters has the square plug, I don't know the model. That one looks pretty beat up. Mine @ 10 years old is in mint condition, not one scratch on it anywhere, I did recently have to replace the keyboard on it too because some of the keys stopped working even though nothing has ever been spilled on it???
the keyboard data cable often rot and get scratched easily when re-inserted into the keyboard port on the laptop. It is bad design, laptop manufacturer use port that bite & scratch keyboard's cable copper and damage it.
the keys are good, the keyboard are good but the contacts on the data cable is damaged, that's why some keys won't work.
Lenovo is a chinese company with chinese reliability standards for its products.
