i would just like to add that on my acer 1644 i only have one battery which is for some reason listed as BAT1 under /proc/acpi/battery...
i assume that this is the reason why im suffering from similar problems with gpm...when i unplug AC it always tells me 1 hour remaining (with 3 %) and then doesnt change...if i plug AC back in the values for percetage charged remain incorrect and it tells me i have one hour remaining to recharged (though i only unplugged AC for a couple of minutes this time)... so this is also a problem for people with only one battery... -- Dual / Two Batteries, shutdown on empty expansion battery. (GPM does not recognises second battery on hotplug) https://launchpad.net/bugs/60442 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
