No lights, no power.
19v DC in is OK
3v and 5v ALW has power as well but all the rest of the rails are off and the schematic shows they all have SUSP# as input.
I'm not getting voltage out of SUSP# from the EC. The voltage lines going into EC test ok.
SUSP# is 128k ohms to ground.... is this normal? or perhaps a short to ground somehwere? hoefully not in the EC.
The computer was brought into a university repair corner because of a harddrive crash. Whilst they were "repairing" it it stopped getting power and booting
My friend has passed it onto me to have a look.
Hi
Have you checked RSMRST 3.3V and S5 3.3V ? and any activity on external mouse or keyboard ..lights or anything. Missing anything reflash bios so let say the dcjack light don't light up when plugged in thats another sign to start with bios. If it's a two chip board meaning bios& EC then you need to relash both.

You could always check cmos battery it should be 3v or more not lower if this board uses a amd yes this could cause it to be in limbo also unplug it for a few min worth a try if it's a Intel model firm ware these days are very common to fail on laptops as much as 60% of my repairs are bios 😳
