Bug Description

Binary package hint: acpi

my NEC P550 's battery is not recognized by Ubuntu 6.06. In Ubuntu 5 it did work.

hooglander1@Hooglander1:~$ cat /proc/acpi/battery/BAT1/state
present: no

There is only one directory in /proc/acpi/battery/

The output from dmesg:

Does this behaviour still happen with Ubuntu 6.10?


Changed in acpi:

status: Unconfirmed → Needs Info

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this linux-source-2.6.15 kernel bug to the new "linux" package. We appreciate your patience and understanding as we make this transition. Also, if you would be interested in testing the upcoming Intrepid Ibex 8.10 release, it is available at . Please let us know your results. Thanks!
