Hello All I wonder if anyone can help me,
I'm trying to fix an Asus GL752V.
The laptop turned on with only the BATT/PW LED's showing on the front, no display/POST.
I found that a MOSFET near the top left side of the SSD bay had blown rather aggressively, (black skid mark see pics) I removed the blown MOSFET and tested the one to the left of it, also blown (short on all pins), I tested board for shorts after the removal all seemed ok.
I replaced both MOSFETS and did a short circuit test all still good (well low resistance on right FET from GtoS red flag?)
I powered on the laptop without memory and the PW LED came on, so I thought all was good, I then installed a memory module turned on again and no power no lights, checked FET's and found both to be shorted AGAIN!
Please could someone guide me to a solution.
PS. I found on power connect (not pushing the power button) after the FET replacement the southbridge was warm, I'm guessing this is not normal and I think its the death knell of this laptop, Is it worth continuing with it?
Any advice suggestion.
Thanks.
