I confirm the similar behaviour on HP nc8430. Problems only start after rebooting, solved only by removing AC and battery. It seams to be a problem with most newer HP laptops.
It does not happen when removing psmouse module before reboot/shutdown. It happens to me in both dapper and edgy. -- Laptop doesn't detect unplugged AC power, special keys stop working https://launchpad.net/bugs/82681 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
