AC Power Loss State in BIOS
Whenever you are away from your computer and the power goes out, your system obviously shuts down. This can be a real drag, especially if you remote connect to your system, as it will be unavailable until you are able to power the system back up.
To combat this problem, there is a setting in virtually all BIOS out there called “AC Power Loss Restore State” (or something to that effect). With this setting you can specify what happens to your system once power is completely lost and then returns. By default, most systems are set to “stay off”, but other options include “turn on”, or my personal choice “last state”.
Setting this option can really help save you a bit of headache in the unpredictable event of losing power.
