Hello, I own an Asus ROG gl764g that won't turn on. The LEDs don’t light up when the charger is connected, and there’s no sound or any other output when the power button is pressed. Replacing the battery didn’t help. I started checking the voltages because I think one of the MOSFETs might be faulty. I recorded the readings in volts and microvolts. I also tested for continuity to ground—blue indicated a short, green meant it was fine. I found some schematics for a similar board, which should match what I have. Could you help identify the exact issue? Thanks.
