I'm going to try and make my old G580 bootable so that I can attempt to reset it and install Linux again.
For those who don't know, my G580 wouldn't boot into anything (it showed a black screen) and one of the things I tried to do was replace the CMOS battery. Unfortunately, it was stuck because it the camera LED was permanently (when G580 was active) on, my fans were running, but the screen wouldn't turn on. And it was stuck there.
If anyone has any suggestions, that would be great.
