This notebook was damaged by liquid on keyboard.
After cleaning motherboard, pluging power adapter charging battery led on, pushing power button led on but not fan and not video.
After many attempts now motherboard is dead.
Checking PL7 264 ohm to ground
PL6 1,5 Kohm to ground
PL15 9 ohm to ground
PL14 9 ohm to ground
19,5 V is ok
PQ 16 and PQ17 pin 5-6-7-8 all 19,5V pin 4 0,4V pin 1-2-3 0V
Probably PU5 damaged?
