Hi all,
History of this board is liquid i believe but someone has cleaned and messed with U7200.
Anyway it's dead - when connected to PSU it draws 1.4 amps and then straight back down to 0.02.
All the rails are present when it's first connected and sometimes it stays on and cpu/gpu get hot but then it powers off again.
U7200 i have now replaced along with C7202 and R7202 as they were fucked with.
PPBUS = 12.6v
pp3v42 = 3.42v
Currently it is in S5 obviously but S4 is working but only for the split second it powers up.
With no other hints i am lost, any ideas?
Update: When shorting pads (SMC_ONOFF_L) it powers on and then off again.
