Battery Critically Low at 85%?

Solution 1:

From fix/workaround found in this thread.

For 11.04 and older just run:

gconftool-2 --type bool --set /apps/gnome-power-manager/general/use_time_for_policy false

For 11.10 run:

gsettings set org.gnome.settings-daemon.plugins.power 'use-time-for-policy' 'false'

This worked for me. It doesn't fix my underlying issue, but it keeps my laptop from continuously suspending.

Solution 2:

People who had same problem I installed Jupiter for them that tend to solve the problem of critical low level of battery in laptops. If you are experiencing such a critical battery level then you can try the following:

sudo add-apt-repository ppa:webupd8team/jupiter
sudo apt-get update
sudo apt-get install jupiter

Thank you.
