Asus K53E. My OS is
Ubuntu 12.04.1 LTS. When I installed Ubuntu,
battery status was shown but after a month it stopped working. Now I'm not warned if battery level is low or something happens. Laptop just turns off.
I know how to fix this, but this is not permanent decision. What I do is: I leave my laptop to work on battery until it turns off by itself. Then when I turn on laptop again, battery status is shown how it has to be. But after a day or two status is like before.
Could anyone help me with a permanent fix?
