[@retrocomputinggrotto]

Big companies like Lenovo or HP or DELL would normally just say the motherboard is faulty and needs replacing, I've never heard of any of them employing staff to actually fix motherboards like Sorin does, they just tend to have FRU's rather than repair anything.

The MOSFET in the bottom right at 7:03 has flux residue on the top side, indicating it's generating a lot of heat. This could be the cause of the issue.

[@Madscientist9898]

The customer is BS. Lenovo would never try to diagnose a board and list what is specifically wrong with it. They will just replace a component such as the main board, memory module, drive, etc. not give some shady list of what they think is wrong. My thoughts are the customer poked around the bored a bit themselves after watching a few of your videos realized they couldn't fix it and made up some BS story packed it up and sent it to you.

[@Drottninggatan2017]

Still, the customer is always right.

[@alienpioneer]

Yeah, especially specifying IC and pin number, lol.

[@everyhandletaken]

Definitely agree that Lenovo didn't diagnose this laptop, but I feel that it is more likely a repair shop with a Lenovo sticker on the window & the customer then believing it was a Lenovo-owned service centre. Either way, misdiagnosed, but the laptop now has a bit more time before retirement 🙌🏻

[@faustasazuolasbagdonas123]

I don't see why the customer would waste time making up that BS and pretend that it is from the service. I think this actually was in a service and he believed that this information will actually be helpful for Sorin. Maybe this was not a Lenovo service but a Lenovo authorized service center. Once I got an Asus laptop which the customer first brought to an authorized service (I think I verified this but this was a long time ago so I am not 100% sure now if I verified). The service prepared a report which had a photo of liquid damage on the mainboard. The customer told me that this liquid damage occurred long before the fault. The report also included a useless technical description of the fault, a repair price which was similar to or higher than the laptop price (which was 6 years old), and maybe their conclusion that it is not worth fixing. I fixed it by replacing an LDO. Then I carefully tested it and it worked fine. Until I returned it to the customer...

1.2 amps can seem slow, but that is what a good charge controller should do when the battery is close to flat, it should start to speed up at around 10~20% charge, and then slow down at 80% again.

It's really complicated when you have, in a big company, lots of admins above you, in some cases they give you a small amount of time to fix the fault. They come with power points with graphs, yeah, some professionals, do copy pastes from emails as soon as the fault is complicated or go out of the script, lol.

There is no reason, just old parts, mosfets is probably one of the things that fail the most.

[@SymbolTech21]

@fabini14 if a MOSFET fail there is a reason. So soldering in a new MOSFET may can work only for a week and then fails again so definitely you need to identify also the reason why that MOSFET died to eliminate also the cause that makes that MOSFET to die!

​@@SymbolTech21 manufacturer flaw design, thats why this 20A mosfet dies

[@SymbolTech21]

@poklop252 no on earth that a laptop will draw 20A current so if this MOSFET died is because something in the circuit after the MOSFET have a problem. This means that need to investigate what is wrong on that circuit that made the MOSFET to die

I used my Samsung Galaxy tablet for years without any problems until one day it crashed while using a banking app, reset itself and then shut down completely. My tablet hasn't turned on since that day, and I can't see if it's charging. When I took it to the authorized service, they said it was a foreign product and they didn't handle repairs. However, I bought it from a Samsung store in a shopping mall. It contains very valuable pictures and videos for me. Since I live in a village, I can't go to the city often. Can you make a diagnosis by looking at how the fault occurred? Because if the battery or screen needs to be changed, I am thinking of ordering it online and installing it myself. Have a nice day.
