Smashing repair jonny, another recovery :-D. The only bit i remember with mos fets is the channel polarity is not the polarity of the gate input to switch the fet on...... or something like that. I hope the owner of the dell appreciate you.
I have a question, I've serviced a few laptops mainly preventing perfectly viable ones from ending up on the scrap heap. I noted that some only require thermal paste on the dual die CPU chip but not on the chipset die, bit of a hobby. Have you encountered this, I've read up on it and some chipsets don't like to be at the same temp zone as cpu. That was a nice fix and think all laptop power supplies should use Dell's blue light on the charge plug. Liked and Subbed
I've not heard anything along those lines. Might be true but my theory is if they build the heatsink with a connection to the chipset there's probably good reason for it so I'll maintain that connection. Maybe in cases where the laptop is full of dust, sits on something that blocks the vent or anything else that prevents normal cooling then it would come up to a nasty high temp with the cpu where maybe it wouldn't if not connected and likely where the issue might be. I'd wonder how those stating this come up with that idea as you'd need to take two new units and remove the heatsink connection and run them at similar stress levels until one fails which could be months. These things are 1,2,3 years plus before we see a failure and in my limited experience it's rarely a chipset fault. Appreciate the comment and sub 🙂
Good repair mate - well done 👍😉

The owner of the computer shop that can't do this stuff sure does 😉
@@JonnyFix Smashing, more income for you :-D
