Acer Predator GX-791: Keyboard, Power Button and Battery Reset not working

Hello everyone,

Yesterday I encountered a serious issue with my Acer Predator GX-791 laptop, and I'm hoping to gather some ideas or information here regarding the possible origin of the problem. While I was playing Rocket League, my keyboard suddenly stopped working. However, the game, screen, sound, and mouse were functioning perfectly fine. Initially, I assumed it might be a game-related problem, so I attempted to shut down the PC. Unfortunately, due to the keyboard not working, I couldn't tab out of the game. Next, I tried using the power button to turn off the PC, but it also failed to respond (even after holding it for at least 15 seconds). This raised my concern further, as the unresponsiveness of the power button seemed unusual.

My last try was to utilize the Battery Reset Pin, as I was certain it would allow me to turn off the laptop. I inserted a pin into the reset hole and waited for at least 10 seconds, but nothing happened. At this point, I had to resort to manually unscrewing the bottom cover and disconnecting the battery, which is not an ideal solution while the PC, especially the fans and hard drives, are still running.
Befor disconnecting the battery, I again tried pressing the battery reset while the cover was off, now sure it was pressed thoroughly, but again nothing happened. Fortunately, after dis- and reconnecting the battery and experiencing a relatively long boot phase, the system came back online and has been running without any issues since.

Currently, I am conducting research to understand the root cause of this issue and prevent it from happening again. If anyone has encountered a similar problem with an Acer laptop or has any suggestions regarding the origin of this issue or why the usual reset methods didn't work, I would greatly appreciate your help. Thank you in advance!
