I recently got a new laptop (Lenovo T500) and decided to upgrade to BT3.

I've found that I can boot off a CD or thumb drive when plugged into AC, but not while on battery power. Is this typical behavior?

When it fails, I get the Loading /boot/vmlinuz line and the Loading /boot/initrd.gz line. Then the screen goes blank and the system restarts. Over and over.

When booting off of AC power, it takes twice. The system restarts once (like mentioned above) and then boots OK after that.

Any help would be appreciated. Thanks.
