Hi, i have a g531gw, the issue is i have power on the board, no short or low resistance anywhere, i have 5v, 3.3v, 1v, the laptop charge the battery normal, but when i press power it try to turn on for les than 1 seg and turn off, on the second it turn on all the voltages are present, vcore gpu core, but for less than 1 seg, and if i press the power multiple times the laptop sometimes come on but with the discrete graphics disabled, i really lost on here i try everything i know so far and nothing
Here is the schematics and boardview (is in pdf but is better than nothing)
Hi Alejandro, from what you said, sometimes the laptop turns on even when you did not do anything to the motherboard, I think the problem is not anything shorted, it could be the BIOS chip is corrupted. You can try to hold down the power button for 60 seconds to clear the BIOS to see if it helps.
Wish you luck and all the best.
Hi thanks for the repply, i already reflash the bios with to know good bios dumps 🙁
