Plug it in, no lights. Hit the power button, nothing. Hold it down (saw some suggestion to hold it down for like 40 seconds), still nothing. I haven't tried opening it up yet. I don't even care if the battery is toast, I'm fine with it being tied to a wall adapter.

It's probably about 8 years old, so obviously it is slow by modern standards, but at the time it was fairly high-end, so it might serve my purposes as a secondary machine.
