[ale] Preventing reboot on short duration power loss

[Andrew Grieser]

Thanks to everyone for the advice. I bought one from Microcenter earlier this week, and went to hook it up when it complained the outlet wasn't grounded. Turns out, even though the outlet is a three prong outlet, it wasn't actually grounded. So I had to ground it (thus the delay), but now everything seems to be working. I just unplugged it from the wall, and it switches over to battery no problems.

I did buy one with an AVR because, daily, my confidence in the power grid around here is lowered.

I have one last question. If this outlet wasn't previously grounded, would the surge protector have even worked? Do surge protectors work on ungrounded outlets?
