I have my dads laptop here, it’s SSD had started failing and the keyboard had a number of dead keys. It also had no working camera since we fitted a new motherboard a few years ago.
So I cloned the drive over to a new one, and took it fully apart to get at the keyboard.
This much I think went OK. I figured I was going to look into the camera after I have the first two sorted, but it turns out that the camera wasn’t working because of a bent pin which I didn’t check before re-assembling.
So, on trying to turn it on, there was no signs of life. Presumably the bent pin made contact with its neighbour. I bent it back out of the way, and tried again leaving the camera disconnected, but still no signs of life.
Does anyone know where I should start? Or have access to schematics etc?
The shorted connector does look like it was the (presumably) 5v line touching the neighbouring signal line, but it goes in to a via and I don’t know where it goes from there.
I have checked for shorts at the charger, 20v enters fine and gets past the first 2 mosfets and the current-sense resistor.
On battery, it similarly gets the 8v through the first inductor and pair of mosfets.
Checking all the inductors some are very low resistance to ground, but I do not know if this is low impedance. I have an old board that died in a similar way a few years back for spares, and its readings seem similar.
I tried looking for schematics for it, but they all seem to be behind paywalls that are more expensive that a replacement board.
I did manage to find this to reference, put I am not quite sure exactly what it is telling me… though it does seem to suggest some of the inductors have “low numbers”.
