[gpm] ACPI -correct without AC- measures a power of ~720 Watts when AC is plugged in

[Peter Waller <peter waller gmail com>]

I'm on gentoo, and I'm using gnome-extra/gnome-power-manager-2.27.92.

When plugged in, /proc/acpi/battery/BAT0/state reports:
  charging state:          charging
  present rate:            64645 mA

After unplugging AC:
  charging state:          discharging
  present rate:            4168 mA

And for a good minute after unplugging, the rate is still ridiculously high. This is making gnome-power-manager incorrectly report time-to-empty and time-to-full by a significant margin, enough to make the estimates useless (2 minutes to completely fill an empty battery?).

I guess I need to talk to the kernel ACPI guys to get it fixed there, but I was wondering if it would be possible to have an option in GPM to ignore these obviously ridiculous values.

Thoughts?

Thanks,
