Comment 15 for bug 39413

I have been getting this bug recently as well. I am running a 1.5yr old Compaq Presario v2000 laptop. I've been using Ubuntu Gutsy since tribe 5 came out, and within the last month, after a round of updates, gnome-power-manager says I am running on AC power, with or without AC power present. Also, the battery tab has completely disappeared from the gnome-power-manager preferences gui-window, yet whenever I execute the
cat /proc/acpi/battery/*/state
command in a terminal, it correctly states whether the battery is charging, charged, or discharging depending on it's charge state, and AC power status.
