Something I decided was worth the trouble to set up: Bluetooth access to the LAN in my house so I could browse the Internet on my PDA via Bluetooth rather than Wi-Fi, in large part for battery consumption reasons. I got it set up, but discovered that although the Bluetooth radio I have as a USB dongle attached to my computer is plenty strong, my PocketPC can't quite broadcast to the opposite corner of the house; my laptop was in such a corner, so my father and I decided to move my work area closer to the center of the house. I haven't yet tested to see how good my signal is now.
Upon plugging my computer in, there was an interesting "snap" noise, a distinct fzzzt! sort of sound, and then the BEEP BEEP BEEP of the battery backup power supply in the room complaining that it, like the now-clockless DVD player and now-off floor fan, had no power.
A romp through the five circuit board panels in the room revealed that none of them had flipped.
Insert frantic running about here until we discovered that the power outlet had its own breaker. But that should just be for that outlet, right? That would explain having no power to the computer and fan, but the UPS was on the other side of the room. Surely, despite all the electrical problems with this house (including light switches that throw sparks across the room, resulting in the first of three times the bathroom attached to my bedroom has been rennovated), the moronic electricians who set up the wiring in the family room couldn't have connected all the power supplies in series so this breaker blocked the other ones, could they?
My father reset the breaker. With a click, the UPS began recharging its battery as the DVD player flashed a now-familiar 12:00.
