What kind of device will restart my computer automatically after an AC power failure?

Answer 1

The BIOS usually has a setting that is something like:

Power management/AC Recovery/ON = System powers on after AC power is restored

At least that is what the Dell says that I am looking at right now.

Answer 2

You'd be much better off buying an Uninterruptible Power Supply (UPS) to prevent the computer from crashing during a power failure in the first place. For the average computer they're not very expensive, maybe 40-60 bucks. See an example at the below link.

Answer 3

Best option is a UPS(Uninteruptable Power Supply). The problem is that if your system is crashed because of a power outage then it may logicaly damage the hard drive and refuse to come back without a scandisk, or it may only boot in safe mode. The reason that you 'shutdown' your computer is because that closes the files and cleans up so your next boot is clean.

Answer 4

If you are having AC power failures maybe you should replace the power supply on your box,,, If you DC is shotty you should try a UPS . There are intelligent UPS that come with software and help you set up your disaster plan and roll out with it.

Answer 5

To my knowledge the only such device is your finger - which really is not automatic.

You could configure a 120 v relay that is normally open to become normally closed for 5 seconds when it sees 120 v initially and then wire this in parallel to your manual switch but I really do not recommend this unless you are very familiar with relays and control circuits (and if you are so familiar you would not have written).

Answer 6

your bios may already support automatic restart after power failure.

Answer 7

Wouldn,t a better way be to get a UPS, so it stays on
when the power goes out.

Answer 8

your own computer will do that. desktop, right click properties click on screensaver, at the bottom click on power options
