This laptop was dropped on the USB-C power cable, while it was plugged. At the beginning of the video you can see the frame of the laptop around the connector is even bent. The connector was pushed into the laptop. No wonder all the pads got ripped off.
The reason for the dispute, I think, is that the connector from the charger has been hit while it was in the computer. Or it could be what you do with the contact at 10:03. You wiggle the plug while pulling it out. You should always and only always pull out contacts straight out, no matter how tight they are. Otherwise they break.
I hate laptops with power connectors that aren't designed for repeated use under stress and excess heat.
USB connection points suck and most barrel connectors also suck.
They get hot and weaken over time. I've had more than one laptop jack melt from continuous connection to a power supply. The batteries get bad and you end up running them almost continuous from the wall power supply.
I'd say your in the ballpark cost wise to the owner to repair this. It's time consuming work on these poorly designed power connections.
If most consumers are like me I would say don't bother to fix it as the money would be better spent investing in a new laptop.
If Biden manages to kick off WW3 the supply of new computers may dry up and then we will be forced to repair rather than replace. Until then it's still a disposable commodity.
I hate to see these going to the scrap heap as much as the next guy but they are not really designed to be repaired.
As a kid in the 60's I can still remember TV repair men making service calls to our home to fix our TV. Those big console TV'S were heavy to move and too expensive to simply replace when parts failed.
The last few TV'S still made in the USA had switched over to replacement boards inside to speed up repair time. It was the beginning of disposable electronics.
The door to door TV repair work was heading into history. Anyone else remember seeing those ads in magazines for schooling to be a TV and radio repair man?
Like the ice delivery services being replaced by the refrigerators, the TV and radio repair shops were absorbed by progress.
I did port swap on some of the Huawei laptops. Those are pain to do, I ONLY use low melt solder to take the old port out because there are many small a fragile components around (like this LED), and the pads are easily coming off. And even then I have pad or two to rebuild.
I certainly do not envy you this job
Requires experience and a very steady hand.
I agree this connector has been abused beforehand as the damage seen clearly is from the connector been drawn sidewards.
Would like to see how you handle this in part 2.
Thanks for the video
I hate it when people want you to fix a laptop but do not give you the power adapter that they are using on the laptop. Depending on the issue the adapter could be the cause or a contributing factor to the problem.
I bought 2 laptops from my local dealer, one lower spec one for my mum and a better spec one for me and I did notice that the higher spec machine had a seperate power jack socket as apposed to an on the board type on the cheaper machine.
So it can be well worth the extra money at purchase for a better spec machine as the later repair could be the difference from a simple repair to a fiddly, if possible, one like this.
I'd love to see it repaired, please 😊
...You did not pull the pads off, they were already off. (see video 🙂)
Great work, great video(s)!
First thing I would have done is check for a short on the main power rail, if OK, then inject battery voltage at the battery connector and turn on which proves mboard is OK, then check power in ar usbc.
With UV conformal coating in additional to using UV light the heat from a rework station can help cure the conformal coating
Good video. Hopefully you have a fibreglass pen to scrape that solder mask off.
Nasty...that was my suspicion right from the start. As you say there's usually a standby even before the power gets processed, the fact it wasnt even there made me think right away of the source. I see a lot of these, my heart sinks every time...lol but that was a good one, impossible to tell how they managed that.
28:01 - It looks like the USB-C cable got bumped pretty hard sideways, moving the guts inside the shell of connector.
I love having my 500 USB connector set.
Good diagnosis!
Looks like someone was playing football with it 😄 Nice big via's to connect magnet jump wires to, if you wanted to go at it that way. A lot less work and hassle than repairing the individual traces with tweezers and new traces. But maybe that would mess up the data wires with cross talk!
Yes it was enjoyable and I learned from it. Thank you 👍
I’m sure you are right, but is it possible to scrap and tack on a few wires to check it responds correctly before asking the customer for commitment? If the charging control circuitry has been affected your work may be for naught. Keep up the great work 😀👍
Hi! I am a subscriber of yours and a great fan of your work. I have a problem with a Gopro Hero 4 black that is not powering on.. I've tried everything they say and after contacting gopro support they said to recycle it.. They do not offer any schematics or information. But I can't afford a new one at the moment so I had to open it. I don't have a thermal camera but I can feel that a big chip is getting warm / hot when the battery is connected (or the USB charger). There is a transistor / diode on the board named 2305, that has no voltage on the collector... I've seen a video waying to connect a strap from the collector to the 5v supply.. but I wouldn't try that without some schematics.. Do you have any idea where I could get some information? Maybe a schematic or a crude diagram? I'm not a pro electronics repair guy, I have experience with guitar tube amps and through hole electronics but this is very small for me :) Also, I can't find any techs around here, in Romania that are good with this stuff. I would GREATELY appreciate any info / advice. THANKS!!! :D
Having a suspicious mind, looks like a bodged previous repair?
Looks more like it was dropped while on charge, or someone tripped over the cable.
we are waitting for the next vedio
31:00 This is why when buying a laptop don't buy one that uses USB-C for power hehe! Definitely don't put new pads on the board, waste of time. The correct way to fix that is first mount the new connector then scrape the blue mask off the traces and attach micro-wires from the connector pins to the traces. I've done that sort of work a few times and it works pretty well. If you are left handed start from the right side or left side if you are right handed. Then you won't accidentally disturb the wires you put down with the soldering iron. I'm sure there are a lot of people (i.e. noobs) who will want to see it but the reality is it's a fiddly job so just get it done quickly minus the camera and move on. There are already plenty of vids on YT showing the exact same repair.
Cool stuff...nice job! Love your videos.😊
Looks like a knackered USB-C connector to me as no connector should have pins soldered to the PCB at that angle. That's some nasty damage Rich and will take patience and some fine skills on your part which you no doubt have. What a pita!!
All that shielding just says to me that the design of the PCB is bad, properly designed PCB's and circuitry produce very little EMI. It could be that the shielding is to prevent external interference but having it stuck to the board is ridiculous and nasty imho.
It was obvious that the pads were already ripped off before you put any solder or heat to it. Time to get out the relife pads or wire and get to repairing the pads. Looks repairable to me. Have seen far worse and made a successful repair.
I would like to see you make the repair.
Hi Richard.. can u please help me identify. W27t. 6 keg ic on that board...
It's below f411ce6.
Both seem to get hot no datasheet..maybe a ohm reading on caps..or resitors if u can
A simple barrel jack would be a much better choice if it was a standard for laptop charging.
Is the usb port next to the charge port loose as well? In the past I have scraped off the board solder mask and soldered straight to the tracks where possible, hopefully there will be a part 2!
They were obviously ripped off before you touched it
0:10 Huey, Dewey Louie, that's not Laptop brand, that's the nephews of Donald Duck.
handy andy 😄
Interesting that the design had those pads/traces put at that type of angle. "Maybe" the device was plugged in, and it was bumped/hit on the a/c in and pulled the socket from the board? Very odd to say the least. Hope you had a wonderful Thanksgiving...
I Have repaired a few of these Huawei laptops with exactly the same problem(all traces ripped off) It seems common with them and I am sure the manufacturer knows because the have used glue over the pins.
When you showed the USB socket next to it, I saw bent pins and thought the USB-C may also be damaged. Both should be replaced.
Concur, laptop appears abused (data pins may be shorting to ground), though using USB-C is asking for trouble.
I believe these are the same type as samsung a50 type c ports.
Since they sent you this one without a power supply and without the back cover maybe some clever guy realized it's the USB that's faulty. And being a clever guy he tried to reball the component. That explains the torn traces Rick
I went on eBay looking for a HUAWEI motherboard. I did not see or hear a model number, so the search nearly fruitless. Most of the boards were about $300, but some were less than $100. Looking at the video, this looks like a Huawei MateBook D14, at the $300 range. With the CPU and memory chips soldered to the board, not a good long life board. Replacing the solder pads very time consuming, and costly. Used Huawei MateBook D14 laptops going for $400-600. I would tell the costumer to cut his losses and buy a higher quality used Dell laptop for that $300-400. Long term they would be much happier.
He said the repair would be about 85 euros so it's cheaper to fix it. It's not a great laptop but it's normal for people with zero knowledge to buy that type of thing. Yeah would have been better to buy a used mid-range to high-end laptop. I got a 4 year old i7 laptop for $400 it boots Win11 in 4 seconds. Lots of noobs buy new because they think they have to but the manufacturers are relying on those noobs so they can continue to sell new products heh!
Hi Richard.. good Video 👍👍👍
Ohh ohh, it's look like a great wired job.😳😳😳
wow , it must of had hard impact or dropped with usb c plugged in .
Repairing stuff designed to be ewast they should be put in jail for such designs.
I pronounce it "who are we". Don't know if that's correct. It's just the way I see it.
Don't they know why the industry standard has been designed to be spaghetti strong. Idiots! Waiting for Super USB (SUSB) coming soon.
My wife breaks these connectors with monotonous regularity.
10:20 The stuff covering the board is kind of good because it will stop 99% of water damage by losers who don't respect their expensive toys which is about 50% of users lol
You need to learn micro soldering.
This is what happens when you drop your laptop while it's plugged in
I see someone has already made the same comment, oops
common proplem of the huawei laptops
That's too many ripped off traces lol
I think Handy Andy might be a Butcher.
30 minutes to check a faulty connector and no repair at the end, that hurt. Sorry to say, I like you sir but unfortunately I will unsubscribe. You need to rethink how followers waste time watching your content.
