I installed Ubuntu 12.04 with Wubi. Well after being completely dazzled with the amount of free content in the Software Centre, I decided to go deeper and start messing with settings. Well after changing the screen brightness the highest level I noticed that there wasn't an indicator for how much battery was left in my laptop. I looked up online on got 2 suggestions on how to fix:

  • Right click on the Unity panel and add an indicator
  • Set it to show in the power settings menu.

Well I did both when I right click at the top menu nothing comes up and setting it to show does nothing either. Then I tried installing something in the Software Centre. I got something but when I activated it it said I had 0% power left even though I was charging and at %100 according the Light in the front of my laptop. So now I'm thinking that it doesn't even recognise my computer as a laptop which is weird because in the display settings it says my screen size is set to laptop.

How can I install it?

I don't know what version it is other then Ubuntu 12.04 and no matter what the icon does not appear with the

  • which Ubuntu version are you using? and what happens when you unplug your laptop - is the battery indicator visible then?

  • If you want to change completely to Ubuntu and the missing battery indicator is what's holding you back, you can boot a Ubuntu session from live CD: there will be no changes to your Windows installation but you should be able to see the battery indicator then. I think it's a problem with Wubi, not with Ubuntu.

I'm not sure if Beeju meant Power or Power Manager. In any case, I was able to solve this problem by:

Click on the power button in the top right hand corner select: System Settings... > Power > Show battery status in the menu bar > Change to When battery is charging/in use

Power

Restart, go back to System Settings... > Power a bunch more options are now avaialble.

Run the Power Manager and see this checked: Show notifications to notify about the battery state. This should solve your issue.

Battery indicator should run with the Unity Panel, but sometimes is inhibited for strange reasons.

You can try to force the daemon to run, writing gnome-settings-daemon in the terminal.

If it works, and you see the battery indicator in the panel, you can add the command to the Startup Applications.

How do I start applications automatically on login?

It work great for me, I hope it can help you!

Make sure your battery is inserted properly, if that was not the issue, go to System Settings > Power and make sure that Show battery status in the menu bar is set to When battery is present.

    since OP "set it to show in the power settings menu" already, this doesn't seem like it would help?
