Power Manager keeps putting in Battery settings on AC

[Domain]

I can't figure this out.

I reformatted my machine to Vista. Everything works right except the power manager, and I can't figure out why. If I start off with the AC adapter, it goes into windows but deploys the battery settings for the scheme. If I remove the adapter, the screen flashes to full then drops to the battery settings, and if I plug it back in, it employs the correct AC settings.

Any way to get it to start up with the right settings? EVen when it goes to the battery settings, it has the plug icon lit, so it's not like it doesn't think it's plugged in.
