I have a similar problem where my battery is not charging. I first noticed it one month ago. After removing the battery and reconnecting it started working and gave me more than one hour backup. Yesterday the problem started again. The battery level shows 92% available and as charging, but it is the same value since hours. I removed and reconnected the battery but no result. Any suggestions. The laptop is 2.5 year old Toshiba L650.
Edit - Problem solved - Shutdown the laptop completely, removed the battery for a few minutes and restarted. The battery is now charging properly.
