Before I do anything, my computer keeps shutting down randomly, no warning, nothing. I can't be on it for longer than 15-30 minutes, and it shuts down, no questions asked. So before I were to do any of that, I need to know what's causing that. Also, one of my quick-touch buttons at the top won't turn on/work. It's the volume control. The volume doesn't light up, and the others don't work at all. They just light up.
When the laptop is off, the quick touch lights, the wifi indicator light, and the SD card slot light stay on. The power is off, but nothing shuts off.
