Huawei D15 shorted PCH - What we should do? Buy a faulty motherboard from ebay? :D

[@brainoverload6288]

Hi Sorin. I have a very similar model of Huawei Matebook and it has the same exact fault. I couldn't for the life of me figure it out until I watched this. You are always a life saver.

[@electronicsrepairschool]

Happy to help

[@brainoverload6288]

@@electronicsrepairschool always appreciate when you respond. If you'd be willing to answer. What did you study to learn laptop repairs?

TLDR he started learning electronics from very young age in school little by little he cumulated huge amount of knowlege which give him THE SORINE aproache to fix things with minimal but reliable solutions 😅

Don’t give up Sorin 😊

[@aldavidson3793]

Hey Sorin, Love your channel. I have bought loads of boards from this Company and all so far have worked without any repairs having to be done to it as they pull them from machines with various other faults like screen etc.. so go for it. :-)

[@רונןמלול]

Hey I have been interested in electronics for the past few years and watched your videos during that time. I want to thank you for 90% of my insights and curiosity about electronics came from these videos and as a "beginner" as you call us I say thank you for the videos. Regarding the decision whether to buy the card, I would say: of course buy it. And that's just to get the pure satisfaction of repairing it.

[@agrifurb]

I've bought off that seller before. One board was just a shorted cap and another was a corrupt bios. Definitely worth a try.

[@darattaqwa]

A lot of sellers now accept returns, if they do, buy 3 and only keep the one (or none) that you know you can repair, be open and transparent with the seller, if they are genuine they won’t mind you taking readings as long as you don’t physically work on the boards, large sellers don’t waste time quibbling over returns (they have a dedicated returns department) and they definitely don’t risk getting negative feedback on eBay, and even if the seller does not accept returns, eBay will still guarantee your money back, with eBay the customer is always right

[@zoko1982]

My suggestion is to buy the motherboard, there is a good chance to fix the laptop. Worst case scenario, if cpu is also faulty, you will have spare parts for future laptops, which is very handy at a given moment when you need some spare parts... It's worth it for that amount of money.

[@jameswhalenjr.5833]

Can you see if the web site has sold any of those boards and then see what the other buyers might have commented about the board they bought?

[@Dr.muthanna]

go forward Sorin you should take that challenge

[@erichaynes7502]

You got to buy the motherboard. It's not expensive and it will be a learning experience for both you and us viewers.

[@SURGE101]

Take the gamble sorin, I think it’s worth a shot going ahead and buying the board.

[@Darkmonism]

Hi Sorin, thank you for the video. I had got in touch with you with a similar model motherboard with the exact same issue you found. Think it got damaged by an electrical surge by the sounds of it. You are having the same thought process I was having. I have looked at the motherboards you are talking about thinking is it worth it? I will see if I can find out more. Good luck with whatever you decide. Dave Powell in the comments did buy a couple and found simple faults to fix. Others have said this seems to be a common fault on these boards. I wish success with your choices.

[@ronlevin2339]

You can ask feedback of this sellers, specially zero and negative ones, sometimes a lot of info can be found there about this seller

[@robertbaker8286]

buy the board and finish the story, don't leave us hanging lol

[@kaiserkhalil1]

Sir please please explain laptop battery circuit also why new batteries do not show voltage on multimeter if battery is disconnected from laptop.

[@vancedyoutube-os4uo]

Because it has an enable switch and most probably it works with ground. Once you enable that switch it will start voltage on output. Check the battery connections diagram before doing this.

[@gaffarmart1728]

Buy the board Sorin, u will 100% fixit, u are a "GURU"

[@Stabio_PL]

*Go forward Sorin!*

[@Swenser]

I recommend putting audio out port on your multimeter and playing beep sound through hifi system. Get as much clarity bass and treble. Ask seller to check resistance of coil.

[@CraShRO]

Cumpara placa, merita riscul, pretul este bun. Chiar daca a fost verificata placa inainte de alt tehnician nu inseamna ca nu se poate repara. Sunt multi tehnicieni care lucreaza la service-uri mari dar habar nu au electronica, poate detin un maxim 5% din cunostintele tale :)

[@nathanhitchcock7307]

But I had an hp 15" x360 with an i3 processor. I wanted to upgrade it to an i7 so I bought a faulty board off eBay. That board had a diode array that was bad on the webcam circuit preventing it from booting. But it was an individual seller like you mentioned - not a company

[@knightwar3]

Even with 5amps it barely shows up on thermal camera, could it be the dried thermal paste is blocking the heat?

[@justinc9991]

Get one sorin, give it a shot

[@mojoNoodlz]

Most faults seem to be with other components on MB, not the chipset, so reasonable chance you'll get a MB with a working chipset. Many companies just discard faulty or even surplus items because it's the cheapest option for them. If you do buy from that ebay seller, good or bad, you'll still end up learning something along the way.

[@BootedTech]

Brand new? Did they not get warranty, unless they broke it.

[@Stan-mh7bf]

Probably stolen

[@fabian11235]

They started selling these from 2020 onwards so its probably just out of warranty.

[@kpolat789]

Why do they have so many of the mainboard? Probably they have the same factory caused cpu defect ?

[@JustMe-in5jn]

I would buy the board. If its good you make some money and have a happy customer. If its bad, o well. Gotta try Sorin.

[@ДимитърАндонов-ъ7е]

Bro they explicitly said they sell you foulty motherboardz you can't retrieve your money, it's not that easy :)

[@marksutherland774]

Doesn't work like that. The board is faulty, all they need to say is faulty unknown board doesn't work. That's a scammers approach, you know the board doesn't work so buying it then trying to get you're money back cause you can't fix it is a scammer. It's a good way to get blocked by a seller to whom you might want to buy more stuff from in the future, I'll give you that.

[@GregM]

If someone sells a motherboard for parts as is and specifies it does not work then you are not going to get your money back.

[@mihailelea]

Eu cred ca ar trebui sa-i explici clientului riscurile si sa-l lasi pe el sa decida. Adica, ori il pui pe el sa cumpere placa, ori o cumperi tu daca va intelegeti sa o plateasca el. Sunt sigur ca-si va asuma riscul pentru ca nu prea are ce face. Decat sa cumpere alt laptop va risca 30 de lire. In felul asta tu esi oarecum acoperit...

[@bahadoromid3554]

Dear Sorin , It is most likely that the replacement damaged motherboard has the same problem and this soc package problem is common on this motherboard.

[@fernalication]

I'm wondering why the customer's letters are completely the opposite what's happening on the computer

[@VISION-viz]

Hi Sorin, i would buy one just to see what's wrong with it, don't count too much on their technicians !

[@pirelli77]

It's sad, 🥺but sometimes you can't do much, you have to set limits. I would risk it and buy the motherboard, but the customer has to agree, they will bear the costs regardless of whether it works or not.☺

[@WeFixTvs]

thanks for video

[@repairtech9320]

If anyone at that company can use a multi-meter, ask them to measure that coil where you had 0 Ohms short.

[@FrankDisseldorp]

High chance that the main-boards have the same issue. I suggest to wait until a (intel) Huawei D15 with a broken screen pops up on E-bay.

[@AP-hz8or]

sorin yout meter buzzer is killing my ears have volume up to hear you but when meter buzz it kills the ears too loud not sure if everyone else thinks too loud

[@SidneyCritic]

You would have to search if it is a common fault with that laptop.

[@deleanuandrei9612]

Damn it... even if the first one has the same issue I would buy a second one. what are the chances to have 3 boards with the same issue. It also depends on how much do you plan to charge the customer, you might explain this to him and add the cost of the board/boards to the bill.

[@robertmay2665]

Can you get a guarantee on CPU or chip set with full refund if not working.

[@berrywin]

Quote:"It's taking four amps and noting is getting hot. It's crazy". Well not so crazy because heating up a component is the product of current AND voltage. Example 4 A and 0.1 V equals 0.4 W. 1 A and 2 V equals 2W. So a high current doesn't mean a high power! Just a side note from an old electronics engineer ;-)

[@marksutherland774]

You'd be surprised, I've bought laptops from companies like that, no display and a quick short of the bios pin later, bingo, working laptop. Bigger companies get these to clear and are unlikely to test them , they likely get them for next nothing or nothing so they're not gonna waste time checking them if they can get £30 for doing nothing. A solo trader might do that, not a company.

[@SigmaWorksSW3D]

I would also buy if customer agrees to pay that extra

[@Arachnoid_of_the_underverse]

For the £30 its worth a punt and you could contact the owner of the laptop to ensure you would get covered for the cost if its faulty.

[@thegreathitsstation]

Cumpara placa ca la pretul ala e buna si de piese. Cambrige doar le desmembreaza si le vinde pt. piese,nu incearca sa le repare

[@dericku7]

Buy it!

[@icommandoi145]

ask the customer if they want to do that, no point taking on the risk yourself but also it's a 50/50 as you don't know what IS faulty on the ebay mobo... It would be really bad luck if ALL the mobo's that are faulty have the exact same fault as this customer board... :D

[@DannyWilliamH]

My general Ebay rule is that if they are a mass-volume seller of "untested' electronics, they're knowingly selling tested trash. You have to look for individual sellers selling their broken item to have a better than 10% chance at it being fixable and/or having has no prior repair attempts. At best you'll find bulk sellers of broken devices that can't test them all or it would be a waste of time to test beyond pressing the power button. Yet, even those are rare. If they have a long history of selling "untested, as is" tech...it's 90% unfixable garbage. Why? They're selling because they already deemed it unfixable AFTER a repair attempt or ten. There are rare exceptions but it is mostly the rule. I don't buy from stores or people moving a lot of one thing if I want parts or electronics I want to repair. I only buy from the person posting the random item just to get some money for their broken item, likely to buy another.

[@deleanuandrei9612]

I disagree. I ust bought a lot of 4 laptops sold as untested (due to absence of charger) and 2 of them are in good working order, one starts but the battery is dead and the 4th one is dead. so I guess there are out there some guys that are not selling shit.

[@malc568]

I now say "and it's loading the Windows" when I get a computer working again.

[@deleanuandrei9612]

If you make sure that's not a usual fault of that laptop, for 30-35pounds it's worth the risk.

[@Rawcrath]

I would buy it just for the content. Otherwise I don't think is it worth the risk.

Buy 3 boards, they all can't have dead CPUs. At least you have spares for future repairs.

Explain to them you want just 1 chip and if its dead youll pay return postage for another board,if they say no then they probably know its a common chip to fail

Offer the customer to buy the laptop from him or her, if they agree, put it aside somewhere, and sort of forget about it and move on, and the answer one day will come (maybe) think that is what i would do.
