HI all, I have an Packard Bell EasyNote TK 85 which doesn't want to power
on, no led light, all dead.
The motherboard PCB marking Code ies:
PEW91 LA-5894P rev. 1.0
I had checked the power supply, the fuses are good, 19V from the adapter
are present. the first 2 P channel mosfet(PQ 51, PQ 52) are working let pas the 19V. I
measured some voltage on the borad and I found nothing ( PL 27=0V, PL 28=0
V), I do not have 5V or 3V.
The battery charger controller (ISL 6251) is not supplied(VDD=0V), no
voltage inside the motherboard .
Two mosfet have 6 Ohm between sourse and drain (PQ35,PQ36), this is normal?
What I should check?
Best regards!
