Hi trying to repair same board a GL753VD
Symptoms: started with when power is connected the fan would twitch all the time,
press power power light would come on the off, had the board out and cleaned and removed cmos battery and checked for any shorted mosfets non found.
Now what it does is the fan is now still, the board tries to boot power light and other lights come on the cpu gets warm the all shuts off.
So something is not reporting to the pch that is what i suspect how do i find this.
thanks
