LMDE reports critical battery and shuts instantly

Postby tytiger on Mon Dec 19, 2011 9:21 am

I Just installed Linux Mint Debian 32bit on my Asus EeePC 900, and when I Unplug the power cord, it pops up and says my battery is critically low then shuts down after about 5 seconds. :?

(P.s. There isn't anything wrong with the battery, it still produces the normal 3.5 hours of battery life on other systems and reports 100% capacity as well as 100% charge when I'm doing this)

tytiger,

I'm away from my netbook right now so I can't give specifics, but in the power management tools you can tell the computer to perform a certain action (like shutdown) when the battery reaches a "critical point." The critical point can also be determined by the user. I wonder if for some reason the critical point is set to something like 99% battery life and thus shuts itself down immediately?

Thanks for the reply,
When I look under the 'Power Management preferences' I don't see an option anywhere to set what percentage I want the alarm to trigger, nor any other actions under the drop down menu (under 'on battery power' tab), all it gives me is: suspend, Hibernate and Shutdown, but no option to 'do nothing' which would seem like the obvious quick fix.

just an update, its defiantly a bug or configuration error of some kind relating to gnome-power-manager, when i killall -9 gnome-power-manager in a terminal and unplug the mains supply the netbook happily runs on battery without shutting down after 5 seconds (obvious i know)

Are you running XFCE or Gnome? I'm running XFCE on my netbook and the power manager looks like this: http://goodies.xfce.org/projects/applic ... er-manager and the battery settings should be in there somewhere. I'm not too familiar with what Gnome uses though.

I see. Hopefully someone more familiar with Gnome will come by and help you out. I wonder if installing an different power manager will solve you issue.

You can try this, it should fix it. Before changing note down the default options so that you can revert back.
Open a Terminal and type
Code: Select all
gconf-editor


Once it there cascade thru menus and change the following keys

1. apps -> gnome-power-manager -> general -> use_time_for_policy to false
2. apps -> gnome-power-manager -> thresholds -> percentage_low to 12%
3. apps -> gnome-power-manager -> thresholds -> percentage_critical to 8%
4. apps -> gnome-power-manager -> thresholds -> percentage_action to 5%
5. apps -> gnome-power-manager -> actions -> critical_battery to hybernate

Now, when the battery reaches 12% Gnome shows a "low battery warning", at 8% a "Critical battery warning" and at 5% the system hibernates.

Thanks,
I think it''s relating to a bug in the way the Eee PC reports the battery charge as a percentage (100) instead of mAh or something (see link below), this is an old bug that's been haunting me since i got it, they fixed it in ubuntu a while ago but apparently not in Debian, i've swapped over to XFCE for now, i still get a slightly premature low battery warning but i can at least tell it to cancel and enjoy a further 1 1/2 hours of battery life ;)
