## 19. My system has an ATX power supply. It will power off just fine, but it doesn’t turn back on. What can I do to fix this?

This depends on how clueful your motherboard manufacturer is, and isn’t a matter of the OS. You have to do one of the following things depending on what’s supported:

- Set a jumper on the motherboard that means "return after outage"
- Set something in the BIOS that says "power up after power failure"
- Try using something (like a capacitor) across the power button to "push" it for you — this might not work if it needs a delay
- Hack the cable between the power supply and the motherboard to fool it into powering up whenever line power is present
- Teach a monkey to watch the machine and press the power button when the outage is over. This might work, but it creates high produce bills.

If you can’t use one of the first two options, give the board to an enemy. Let them worry about it.
