Similar on sony vaio:

Status: off-line

is shown, no matter of the actual status. This works fine with
a stock 2.4.20 + current acpi patch.

Works for me on Dell Lattitude C640 (so far it seems to be the *only* ACPI
feature that does work for me...) - /proc/acpi/ac_adapter/0/status correctly
shows the AC status.
