Strange. It has an ATI 128 in it.

If I plug the laptop in it works fine, but if I don't my DVD software freaks out on some titles.

What do you think? Too much power draw? It doesn't matter if I shut off the laptop monitor. The other option is that the computer is at 600 MHZ when plugged in but when on battery power it's at 500 MHz (PIII).

Either way, I can't actually watch the DVD on both. I have to choose one or the other.

Working in Windows is not a problem, and I can use both at the same time.
