HI GEYS

I Have a ACER TravelMate 5360 dead
DA0ZRJMB8C0 rev:C
with the AC adapter plugged and battery i have a orange charging light , but no post, not turning on
Schematic attached
voltage present:
EC bios u23 3v
Main Bios U27 0v
power button SW1 3V



pq60
+3VPCU 3V
+3V 0V
MAIND 0V
if i understant will for activate +3V i need MAIND and it come from pq45


PQ45 pin 1 GND- pin 2 6,4 v- pin 3 MAIND 0v

any idea?

This is the explaination of this circuit

Before trigger on : pq46 is off , pq37 on ,pq40 on , pq42 on , pa41 on , pq45 on = maind 0v
When trigger on : pq46 is on , pq37 off ,pq40 off , pq42 off , pa41 off , pq45 off = maind 12v

Start with PQ46 , if when trigger on you still have 6.4 v ( voltage divider you must find 10v and not 6.4v) than pq46 still off so chang it

nb : i presume that when trigger on MAINON is rising = 3v
