Folks, pay attention here. ChatGPT is reported to be "PhD-level or beyond in every single subject" - except board repair it seems. Have a look and prepare to cringe....

This is a Predator PT516-51s laptop, serial number is rubbed off. Board is LA-L211P Rev 1A. Charging light is on, machine draws 2.8a lid closed. If I press the power button, I get a blue power light indicator about 5 seconds, then it goes back off. I pulled the board to discover that with battery and AC connected, battery mosfet 1 light up under thermal. I then verified a short to ground on battery mosfet 2 source. If I inject voltage there, my PSU goes to current limit, but nothing illuminates on the board - anywhere, either side. I removed mosfet 2 but still have the ground short at source....
