Bug Description
After shutting down the laptop, the battery still slowly drains, going from 100% to 70% overnight. And, no, this is not sleep mode. This has been confirmed by other people with Toshiba models such as M115, M100 and maybe others. No such problem in Windows. This is in Edgy, Feisty, and Hardy as well as Jaunty.

I was about to report the same thing; mine is a Toshiba Equium A100-306. It does appear to switch off fully (screen fully black, no disc sounds, onlight goes off), but there is obviously something still eating power (I think about a 50% drain over night; totally flat left in hibernate for 5 days).
I've included a section of syslog that looks suspicous to me; note the bit about USB (I've not got any USB devices plugged in); (Is it normal there there is the remenants of the logs from the shutdown (Apr 22) finding their way into the logs on the 28th when it woke up?)

There are a bunch more of these.
