This reminds me of a weird story...

I went to work at a BBB office once. They turned all their computers off at night and every morning they were back on. It was just "normal" for them.

I can't even remember what problem I was troubleshooting. At the time I was working on IVR systems.

Anwayz, I was working late in their office. Everyone had turned off their computers and went home. At exactly Midnight, every computer in the office turned back on.

I walked around the office looking at desks wondering what had happened. On one persons desk was an alarm clock with a very quiet alarm buzzing. I checked the clock and it was set for midnight (probably a default). About two minutes later it turned off automatically.

I turned off computers and re-set the alarm to go off a few minutes later.

When that alarm clock went off it somehow caused either draw or feedback in the wiring that caused all the computers to turn back on. At the time I wondered if it had something to do with wake on lan.

In any case, I suggested that person take their alarm clock home.
