Arch Linux

reverting to gnome-power-manager 2.24.4-1 [from my /var/cache/pacman/pkg] solved the problem: after reaching 100% charge on battery and removing the ac adapter gnome-power-manager will now, again, correctly update the percentage of remaining battery thus making possible a suspend on critical battery and also notifying me about the low battery level
this makes me think it's a bug on the new gnome-power-manager [from gnome 2.26]

just to be sure it's clearly stated: i use x86_64 archlinux with full gnome 2.26; i cleanly installed arch on this system after xorg-server 1.6 [and gnome 2.26] were moved on extra [stable] so no configs or anything else to remove/alter/.. because there were no prior versions of gnome or xorg-server before these that could possibly interfere with gnome-power-manager 2.26.0-1 [except gnome-power-manager 2.24.4-1 which was updated later than the rest of gnome 2.26 packages]

kind regards

i dug through the docs and wikis and as far as i understand the new gnome-power-manager doesn't use hal anymore but devicekit instead and if i understand correctly devicekit is new enough to be more error prone than hal so maybe it's a devicekit thing after all
the old [2.24.4-1] gnome-power-manager not only shows correctly the battery status after full/100% charge but also keeps track of charge/discharge history for my battery, things at which the new gnome-power-manager fails miserably
following pacman's current dependency info the only package that can drag devicekit on my system is devicekit-power [needed by the new gnome-power-manager, 2.26.0-1] which, in turn, depends on devicekit itself; i can't find any other packages depending directly or indirectly on devicekit at the moment
i'm wondering if anyone noticed/experienced the bug i reported here

I'm having the same problem using x86_64 and gpm 2.26. The issue seems to happen to me after suspend. If I plug my laptop back in after suspending, the applet begins reporting the correct % again.

same problem here, I'm on i686.

Right clicking the applet and bringing up power history shows info on the battery. I noticed that after unplugging my laptop, the refreshed field keeps increasing. It seems that the battery info is not being automatically refreshed. Take a look at this post: https://bugzilla.redhat.com/show_bug.cgi?id=479322#c5

I found a way to wake up the battery. Run this:

dbus-send --print-reply --system --dest=org.freedesktop.DeviceKit.Power /org/freedesktop/DeviceKit/Power/devices/battery_BAT1 org.freedesktop.DeviceKit.Power.Device.Refresh

I haven't tested this yet, but I bet adding the same command to a pm-suspend hook would fix the issue after waking from suspend.

@Jori Hardman: i haven't used suspend EVER on this laptop so i doubt what i reported is related to your suspend problem
however the link you gave on redhat's bugzilla seems to cover your problem [involving suspend] and my problem too, so they might be related [in some way]
the thing is your fix doesn't apply in my case unless i always _manually_ run that right after the battery is 100% charged and i pull the plug
anyway.. as far as i can see the guys at ubuntu [ok, canonical :D ] are avoiding gnome-power-manager 2.26 and their next ubuntu release will come with gnome 2.26 but the power-manager will still be the one in gnome 2.24; maybe they saw there's a problem with the gpo+devicekit duo and they decided to let devicekit earn its territory before they allow it to the 'unwashed masses'; here's the proof: http://anotherubuntu.blogspot.com/2009/02/what-you-wont-get-in-jaunty.html

i consider this one to be really annoying and i think i must be fixed somehow because with the power manager not knowing the battery's real state you might end up loosing your work [from a premature and `unannounced`/unpredicted shutdown caused by uncaught battery depletion]; not a very nice thing after all, right? :|

maybe somebody, somehow manages to find at least a temporary fix to this

kind regards

It's probably solved in 2.27.

please try devicekit 008 and gnome-power-manager 2.26.2.

i just tested gnome-power-manager 2.26.2-1 and it seems to do the job correctly
no more "IgnorePkg = gnome-power-manager" in my /etc/pacman.conf :)
thank you, Jan!
