If I use my Acer S7-392 with the power supply plugged in and powered, then I have no issues. However, if I power up on battery then frequently (it does not happen every time) I will be using it for about 10 minutes and then bang! the whole laptop dies with *no warning* whatsoever. All work is lost, nothing saved, no hibernation, just black screen, no power lights.

 

What the heck is going on? You'll note in the attached images that the computer's power settings are set to 20 minutes (display) and 30 minutes (computer) if running on battery. This happens in almost exactly 10 minutes, and I am not idle when this is happening, I am typing (such as this forum message) when it happens.

 

I should add that I am happy to tinker in Advanced System Settings, the registry, BIOS, etc to resolve this.

 

Thanks!
