hi,

i have laptop sony SVF14N2J2ES, motherboard: da0fi2mb6d0 ref D, it was awash, after i clean the motherboard, i check the VA+, VIN line and 5/3Valw line and there is not short circuit, but there is nothing on line VA, the 19V is on PQ34 on 1-2-3leg, on 4 leg is 19V, but on 5 there is 1,1V, i replacer charger BQ, i check all small elements on line VA+ i replaced PQ35 and still nothing, i put tensios 3,3v on 5 leg pq35 and nothing change, after delete the pq35, 19V show up on 5 leg PQ34 and on 4 leg PQ34 there is 9,8V, i attached 1 page of schematic, can anybody help with this ? what i should check or replaced ? thanks for any help.

Try shorts pins1,2,3 and 5 of PQ34 and plug-in 19V from DC Power Supply.
Then test +3.3V & +5V.

on 5 leg PQ34 ther is signal DC/-C and it out from kbc NPCE985L, so are you sure that there should be 19V ?

PQ34 working as switching, close/open. If this open, 19v must be on 5 pin.

hi sorry, i haven`t time to reply, ok i put 19V everything is ok, but i want to resolve the problem not avoid obstacles, s what you think is damage ? why i don`t have 19v n 5 leg ?

test
-VAOFF
DC/-C
PQ35
PQ34

i replaced pq34 and pq35, but no result that`s why i`m looking for help.

test signals

-VAOFF
DC/-C

One from this closing PQ34
