That sneaky little fella. I love using a thermal camera for electronic repairs. It's also great to show the students when systems are live with fuses and relays showing temperature. Great aid for parasitic drain diagnosis.

What's the device that measures current draw at 0:34? Looks neat

Hi, thanks for the video. I have yoga slim 7 and same problem. Do you have any repair centre? I love in Manchester.

I think you need to dial down the exposure, it seems a bit bright and washed out, noticed it in a couple of videos now, it depends on the light reflections a bit, maybe set it to auto exposure to see how it performs.

and I came here thinking I could fix my own laptop 😥 Appreciate the video though.

Why would you not charge for this repair??

You should try and find an AC supply for the camera, that is what I use so I don’t have to constantly charge batteries.

Love watching you fix stuff, I've learnt lots!
Is it just a general rule that random caps like that are 10u 10v? I recently fixed a dell laptop with a similar fault but just left the cap off the board as I didn't know what value it was, working great and still have the laptop so could slap a cap on there. Without a schematic or donor is there a way to tell?

Well done :-D
Bloody capacitors!, they seem to be failing way too often.
I'm starting to wonder if its done on purpose.
I've got a few ancient machines that never fail, better parts or just luck?
Mosfets going poof is a really common problem in some brands (under rated ?).

first thing first you should have check for power voltage charger, i am no expert but you went straight to the M.B, at the end of the day you fix it but you took the long way

Corporate computing does not care about fixing. They just replace and send this back to the maker.
