Hi all fellow technicians, I hope someone can help me to solve this Asus X45u motherboard problem, all power voltages are available but the laptop still can't respond. this is the result of measuring the working conditions of the switch on the EC chip:
1. +3VA EC ( PIN 26 ) : 3.29V
2. AC IN OC# ( PIN 120 ): 0V
3. +3VPLL ( PIN 127) : 3.3V
4. LIDSW# ( PIN 17 ) : 2.92V
5. PWRSW (PIN 125): 3.28V
I only have a boardview and no schematics, thanks to everyone, in case anyone is willing to help to solve this problem.
