Lenovo IdeaPad 100s No Power - LFC
HTML-код
- Опубликовано: 21 авг 2024
- Quick and dirty repair on a Lenovo Netbook today. Sometimes you can get away with "making good" when there's no need to fully restore the device to factory condition.
Notes: Customer was completely fine with this repair, had no use for the HDMI.
The battery was charging ok, the low charge rate was due to the cable I was using, which was a super cheap USB widget cable I'd cut up.

Graham just admit it; you didn’t want to give it five minutes to get some power in it, you wanted to eat some Oreos!
Always a good call to give the customer their choice of repair options. Most of the time, for less expensive devices like this they will gladly choose the cheap/quick fix, as it is what they were hoping for when they brought it in. Often, they will even elude to this preference with their language when dropping off. "Can you just see if it's even worth fixing. I don't know, it was just so cheap, I'm not sure I want to spend much on it."
If they have ANY reservations, they will not hesitate to request a full repair. Though this only seems to happen when the device, A: Holds sentimental value or B: "Feels" irreplaceable to them.
Wow! Glad to see what an “irrelevant” chip can do to an entire laptop 🤯. Great quick vid 🥳🥰
Hahaha the timing of it taking more amps was impeccable. Great little job Graham 😊
I feel customers in your area are more understanding and pay attention. If I were to explain it to a customer I would get a call within 2days saying the HDMI port wasn't working and it must have been something I did and I should repair it for free. That's why I make detailed notes on the receipt and make the customer sign it.
Just had the exact same laptop in my shop with the exact same issue. The moment I opened it the same iductor was cracked aswelas the "TVS" diode, but the audio amplifier was fine. Removed the two broken components and still the problem presisted so removed the audio amp and everything worked again. Must be a defect with these boards. Thanks for the video helped me figure out the issue a lot quicker than I would of on my own, just cant believe I watched your video a few days ago and then the exact same laptop with the exact same issue comes in through my door :D
HDMI has digital audio coming directly from the GPU. That amp is probably for the headphone jack, since the built-in speakers work.
That could be part of the GPU on board this small most of the GPU still will be by the HDMI port.
@@MartinBarker The GPU is integrated into the CPU, so the HDMI signals should be coming directly from the CPU, maybe with some passive components for filtering.
@@RealNovgorod Need the schematic to fully validate signal pathway and handling.
@Novgorod funny because every IGPU or on main board GPU I looked like xbox, ps3 ps4 and ps5 all have HDMI via an audio amp chip, so I'm fairly sure your wrong and IGPU does not handle the audio on its own
@@MartinBarker No, you're completely mistaken about how HDMI audio works. HDMI audio data is interleaved with the video data and streamed out via TMDS on 3 differential wire pairs. It's a digital high-bandwidth data stream coming directly from the GPU or SoC. Maybe it can use some kind of phy (like ethernet), but usually that's integrated into the chip outputting the signal. There is no audio amp involved because there is no analog audio whatsoever - the audio is a digital data stream mixed together with the video data.
I did a bit more digging and the burnt IC is NOT an audio amp at all! The first datasheet google result suggests it's an APA6003 (15W power amp), but it has the wrong chip size (28pin instead of 16) and would be obviously overkill for the tiny laptop speakers let alone headphones (also the speakers were working after removing the chip). That chip is actually an ETA6003 2.5A Li-ion charger (QFN16), which makes sense, since it's close to the AC plug and supposed to drive a status LED (not populated on the board), in addition to the typical circuitry for a DC-DC converter (big caps and coils). The power-on behavior is a bit strange with the chip removed - I assume the SMC waits for the charging to start but it never happens without the chip, so it just powers on the PC after a while. The total power draw of 5W with the PC turned on suggests that there is no charging whatsoever, so this laptop will be doomed to a tether (and a very long startup procedure if it's unplugged) unless the guy changes the charging IC.
That comment for Old Video but i really want to thank you about it, Vedio title is "Gaming PC Crashes at Random - LFC#217"
"Thanks Man, you're a life saver, this Problem made me crazy. in 18 years of hardware experience I never faced problem like this and i tried every thing bios update, new system, change GPU an drivers even i changed my old SSD to new one because Memtest64 on system and Furmark test doesn't show any errors in this System Ryzen 5 2600 B450 Aours Elite V2 Rm 2×8GB 3200Mhz T-Force DarkZ R7 370 2GB
From Egypt with love Bro may God bless you"
This fault remembers me of something. A hole in the chip? What about this? The most baffling macbook pro fault is that the 50 volt backlight line is right next to the igpu's 1v dataline, so when water gets on the display connector, it sends 50v down to that dataline, in fact literally frying the cpu! Lenovo's also have a great self destruct feature, when the +19v line from the charger touches the charger sense pin, it fries the super-I/O chip, sending 19v to a dataline, sounds familiar doesn't it? I wonder why so many computer manufacturers copy apple, even the bad design choices they copy! Insane!
good too see you again!
How I wish I have as nice shop as yours bro.
HDMI audio is purely digital. No need for an audio amp at the transmitting side.
Very nice :D If only everything else was that simple to diagnose... Thanks!
New knowledge and less landfill 👍
You had me in stitches with this video, definitely no holding back on your feedback. Just to be clear this is not a great netbook😃
Hey just wanted to let you know I repaired the same machine as you, and that the datasheet you looked at is not the correct one. That is for a QFN 4X4-28 pin chip, but the board has a spot for a QFN 3x3-16 Pin. I found the datasheet, it is for the ETA6003. It is a switching charger IC. The only reason I bring it up is because I actually was silly enough to order them from AliExpress and wait a months for it to get here. Love your videos!!
Yes. I too confused. It is charging IC. I too got the same laptop for repair with charging IC burned on the same spot as with Adamant's one. I ordered this chip and waiting for delivery from china ETA 6003. One question, I wonder, how does the laptop turns on and charges battery with no charger IC, in case the laptop with Adamant.
I wonder in this model Ideapad 100s, the charger IC buring is very frequent and what would be the reason for this. Does it causes due to poor circuit built or the user plug in traditional laptop charger 19v?
To be fair, netbooks and other cheap PCs mainly suck because they use those 5400rpm drives or eMMC storage which is basically just a soldered sd card, if only the OEMs spend an extra couple bucks for a proper sata ssd they would actually be ok for basic web use or working on documents.
Ahh I got relaxed after watching your video after long time.
Great help thanks for this, I tried to fire up mine a few days ago with no joy after collecting dust for over a year, Just to do some basic spread sheet stuff, I mean it's not capable of much more you can't even watch RUclips unless it's on the lowest resolution which makes it look like your watching Minecraft 😅, after taking the back off i discovered mine had exactly the same issue, I however don't have tweezers or a heat gun, Don't cringe but i used a lighter and a razor blade to pry off that audio amplifier thing, the circuit board looked a state but guess what it worked, how long for 🤷🏻 but it's working now and was used over 2 hours yesterday and today 👍
These newer cheaper laptops look like tablets on the inside.🤯
Nice fix Graham,it`s always nice to call customer that his bricked laptop is alive again!
Yes, it is a crappy machine, but not That crappy. I bought the later 110s version, because a) I wanted a small portable device as an upgrade to my asus eee PC 900, and b) I had seen on yt that it had a spare slot for a real m2 sata ssd. The win 10 on emmc is still crappy, but fedora on the m2 is perfectly usable (especially when compared to the eee !)
Good one
Oreos in the middle of the repair is important step forward, as its learned
Nice one. Well done. Another saved from landfill :)
The way it looks inside is like they put a tablet motherboard inside a laptop case and call it a ... laptop
I lent a laptop to a friend a few years ago. He kept it for about 18 months then gave it back to me. It absolutely would not start up so I stripped the memory and HDD out of it and junked it. I guess I know why he gave it back to me. :)
The more I look at these videos, the more I wonder if I could have saved that thing with just a little bit of probing about. Pity.
That chip is actually an eta6003 and its the charging ic for the battery.
That Lenovo 100S would have made a perfect "KODI" media player❤❤, Too bad that A6003 audio amp ic is busted for the HDMI port 😔
Quick fix 🔥🔥
nice sir !!!!!!
Not entirely convinced that's an "audio amp" for several reasons: do HDMI outputs have an audio amp on them ? They don't drive speakers directly, so I doubt it. A6003 could also refer to several other things, like ETA6003 which appears to be a battery charger, which might explain the coil next to it (buck regulator). EDIT: I read the description and you said it's charging fine, so it can't be anything power-related. I was actually really curious to see you dig deeper and see what exactly is not working anymore - probably the headphone jack, meaning it's got a separate amp for the speakers, since those appeared to work.
Yea, this comment and McG's comment below saying HDMI is digital and doesn't need an amp has me questioning this as well. Headphone jack amp definitely seems likely. It looks like an audio circuit to me. Closer look at google doesn't give me any useful info either though🤔
A schematic/boardview would be handy if you grabbed the model of the board inside AND was lucky to even find such thing in the first place. Doesn't matter as long as it works, ESP for a budget lappy, but I always like to dig deeper for the fun of it - the "what-if..." route :)
It is indeed an ETA6003 charging IC, not an audio amp. HDMI is digital, so there are no amps involved. The battery is also definitely not charging because the total power draw is only 5W when the laptop is running.
wow this needs a pinned comment to explain what happened with the pc since we found out it's a battery charging chip, nothing to do with audio..
Its not audio related chip, its ETA6003 for battery charging.
Hi, sorry to bother you, how can i know for sure if the Super io chip is bad? some resistors around it have around 14ohms, but 3.3volts power supply is not shorted to ground. When i inject voltage on the resistors around the chip (3v 2a), the chip gets a bit warm and takes 0.31amps, but the voltage on the psu doesnt go down like in a short.
"And we've got a motherboard" Well, if you want to call it that.
Did you notice that part of the broken inductor was shorting out some resistors/capacitors? Obviously it took a hit at some point. It is possible a MLCC in the circuit is also cracked, or just the shard of ferrite was shorting the audio output and therefore blowing the chip.
Yolo = the best technique.
Hi there , in your next video is it possible to tell us how did you put DC POWER supply(V,A,W) on the screen , its very nice . thankyou
Oh my god. This was my second ever laptop. I actually took it apart. It's long gone now...
i think the when the indukter broke, the Voltage spiked and killed the audio amp
how true, and as a beginner, you fix it,, or try then throw it out as you broke a ribbon cable or cable connector or knocked a component off the board...lol but you need to sacrifice a few to get to a point where you can fix them for real.
hello thanks for your videos , i want to know what microscope and arm for the micro you are using ? i ve learn so much with your video thanks again , and sorry for the grammar i m french
Logitech BRIO webcam. They can do really crazy macro shots in manual focus.
They don't deserve the name. They're just big tablets with integrated keyboard.
even tablets would have more power than this for the price, especially the base ipad
I was wondering if I could use a PICO PSU for my Motherboard's miscellanious(24pin connector) components(fans,HDD,north bridge, ram etc) but for my GPU and CPU an external PSU!?
Is the pico PSU going to interfere with my plan to connect the CPU and GPU from a different PSU (external)!! My external PSU is an HP1200 watt server PSU(which does not have the 24pin connector required to power the motherboard but only has 12v+ground 6pin connectors) and the pico PSU is also going to take its 12v input from this (1200watt server PSU) and convert it to 24pin(3.3v,5v) respectively!!
I'm quite good when it comes to soldering and wouldn't mind doing some tinkering to get things to work properly ;).
*_Edit: To make it clear my intensions are to power the GPU and CPU externally and the PICO is only going to power the board through the 24pin connector_*
*Sorry for the long text.*
_Any help is greatly appreciated!_
Have a bunch of dead Ideapad boards. Time to experiment🤓
I'm wondering if that's the same problem with mine. I got it for free, 3 months later sister broke charging cord. Got new one and it doesn't charge
Nice video and fix.
But most of all I wonder how you get your powersupply data in view.
Is it just a camera pointed at the psu and you cut out the 3 displays and put the letters behind it and put that in the video or is it something fancy like a sigrok connection that generates a new view and you import that into your editing program? (or with maybe included software)
My power supply (Hanmatek/Rockseed 305p) has a USB link into software that can show output and datalog. I screen record that, and then in editing I crop and chromakey it. The crop/chroma could be done in OBS as well, but I have a display capture running all the time anyway, so I do it in editing so I can tweak it later.
@@Adamant_IT thanks!
hi guys do you have any idea about my problem
i have a pc and when im not using it i set it to mine with gpu some days i come back from work and i see my cpu fan and my only chasy fan stopped (the chaay fan has a led and its turned off means no power not good cpu temps and idealing) the cpu is 100 degrees and it works in 500 mhz and it fix when i restart
tnx
Can I still used lenovo ideapad 100s for online class without any issue this year 2024
HI, how does one contact you about a repair on a gpu? I really stuck. any advice on who i should go see if not you.
was there also below the amp chip a diode that looked like it was in pieces?
just for the sake of learning, is it posible to change the emmc or soldered ram on those things?
Instead of initially using the power supply, why didn't you use a multimeter to check for a short between the inner pin and the outside of the power connector?
Either/or is acceptable. I tend to plug in a charger first to see how the device behaves before I touch it. This won't do any damage that hasn't already been done by the customer.
What dcps do you use to show on the screen
Hanmatek/Rockseed 305p has a USB link into software that can show output and datalog. The software usually doesn't come with the unit, I had to do some googling to find it, and it's also pretty janky. It works, but I can't say I'd recommend it if software display/logging is something you _need_
Hi biggest fan here although i do have hp notebook pc 15-bs0xx that just died no power no any thing tried diagnosing but couldnt get anything can you help with little guide ill much appreciate it
First steps are to check the power system. Check video #283 to see how to measure power into the laptop, and check for short circuits. ruclips.net/video/qqSZRcIqELo/видео.html
Talk about bad circuit design
so how did you hook the power cord to your power suppliy by what chopping the 2 wires ? lol
Yup, splice the cable to get the positive and negative, set the DC PS to whatever the input rating of the laptop is. This works for many laptops, but not all, as some have a sense pin that also needs to be configured so the laptop can 'detect' the charger. I usually just use a known-good charger, but this is a handy trick for when you don't have the correct one.
probook 450 g2 charging led flashing merci
Thanks. Where is the Disk?
This is an eMMC laptop, there will be a 32GB eMMC chip on the other side of the mobo. They are not upgradable in a practical way.
Technically you could probably replace the parts of the eMMC with 64GB stuff or something, but the amount of work involved isn't worth while by a long shot. These are throw-away laptops 😔
Thank you for sharing all your hard work, help us alot to learn. Quick question, i have lenovo x1 carbon, its not powering on, power button blinks 4 times, fan spins once but not turning on. Any suggestions. Thanks in advance
I couldn't quickly find any details on what the 4 flashes mean... my guesses are "battery is flat" which means the laptop isn't getting power from the charger, or BIOS is corrupted. Does the laptop charge when plugged in?
Hi thank you for your reply. I measured power mosfets, and some capacitors, there is 20v while laptop is connected. battery connector shows 15v. But there is no charging light. Thanks alot
H'mm. Yea I'm not sure without looking at it - I haven't done a lot of charge-faults to know what the common issues are. It sounds like power is getting to the right places, but the charge circuit isn't switching on. I'd be suspecting the power management chip, which is responsible for this, but again, that's a guess.
@@Adamant_IT thanks alot. Yesterday i went deep in diagnostic and found 20v only of source of power mosfets. Nothing on gate or drain. Also its not charging. So i am suspecting its power ic/mosfets. Thanks alot for your guidance
what a sad looking inside
Can you show us what your bench psu looks like? And maybe a link?

What voltage you apply? 19v or 5v?
For this laptop, 5v. Most devices are 19.5, always check the label though.

Wait Why Is that Uk Layout Using the US enter key?!
All computer keyboards have the same enter button in the same location.
@@ReeseL4D Yes BUT NOT THE SAME SHAPE!!!!!!!!!! DID YOU NOT LOOK AT KEYBOARD LAYOUTS
@@VOLTRONDEFENDER4440 Button shape is small because netbook keyboard is small.
All computer keyboards have same layout.
Some keyboards smaller. Some keyboards bigger. Layout is same.
Enter button always above right-shift button. Button shape is not layout. Button can be different shapes/sizes. Understand??
@@ReeseL4D I know that I wasent sure you understand that UK keyboards normally have a iso enter key instead of a US/Australia/Canada enter key

i would have changed the thermal paste
Those ideapads are the crappiest crap
I thumbed up when you said not worth fixing.
However saving it from landfill does make it worth fixing also it could end up being some unknown genders first computer.
Couldn't care less, if you could care less then that means you care at least a small amount.
Good point but this seems to be a paradoxical situation for any of us who even use the expression, 'I don't care at all.' Only when we do not think at all of a situation can we truly be considered as not caring at all, but as soon as we bother to even think of a certain situation we are caring at least a tiny amount. Conclusion: 'caring' is at first a mental awareness. When we care a lot we usually generate a physical action. Thus if we want to care for people for example it must first begin with a mental generation. Also if we intend to harm people it too begins with a mental generation. Ultimate conclusion: guard your mind and generate the desire to help people and you will ultimately increase your physical abilities to actually help people. A strong and healthy mind is dependent on effective mental practices and a weak and sickly mind is dependent on negative mental practices. Everything follows the mind. The 'powers that be' know this very well and use the Media to influence our minds, thus they can control our actions. IF we are awake to this process we can break the spell that Dictators and Mass Corporate Media cast on us. The Mass Media churning out 'fear porn' for the last 20 months coupled with censorship of information opposing the 'fear porn' is a text book example of this.
In my opinion I feel like Lenovos are 🗑️.
