[Pkg-acpi-devel] Bug#609846: Toshiba Satellite battery not recognized by acpi

[taylor]

Package: acpi
Version: 1.5-2

I just installed Debian Squeeze on a new Toshiba Satellite L640 laptop, but acpi doesn't recognize its battery. As a result, neither the system nor graphical applications can access the battery's state or charge.

The symptoms are identical to a bug reported to Red Hat's bugzilla (https://bugzilla.redhat.com/show_bug.cgi?id=664533) and discussed on the Fedora message board (http://www.fedoraforum.org/forum/showthread.php?t=256328) by the owner of a similar laptop.
