Look in the bottom of your screen were it says the battery icon. If it says "Plugged in, not charging" you need to reinstall the battery drive. Turn the computer off and take out the battery and hook it up to the AC adapter. Then turn it on and go to Device Manager. Then uninstall everything in the battery category. Turn your computer off and put the battery back in. This is probably not the problem but it helped me. Keep in mind that this is only for laptops.
