I tried it with a battery and it booted right up. It's weird, there's no play in the power socket, it was working fine last night with just the power supply, and now it's as if it didn't see it.

I did already try the reset and the PRAM battery is brand new out of the plastic wrapper. It does hold date and time when Pismo is working.

I have hooked up everything that was unhooked. I hope this doesn't turn out to be a bad power board. (The one under the trackpad) That's more work. But I have already suspected it once.
