Answer» Hi good folk, This a quite a tale. Of all my years sitting in front of a computer never have I tought the following would happen to me. One day I returned from work looking to charge my 1 year old Toshiba laptop. After about 15 minutes of activity I notice that my remaining battery charge was dropping instead of, well charging. I hovered overed the Battery icon in the lower right corner and the message read: " Plugged in, not charging ". Being a new generation kid I immediately hopped on google to try and solve this. After reading through a dozen articles about said problem I did the following (please note that I have a sealed in battery - stupid I know): " Uninstalled the battery drivers, restarted the pc, plug out and plugged in the AC charger.

Hi good folk,

This a quite a tale.

Of all my years sitting in front of a computer never have I tought the following would happen to me. One day I returned from work looking to charge my 1 year old Toshiba laptop. After about 15 minutes of activity I notice that my remaining battery charge was dropping instead of, well charging. I hovered overed the Battery icon in the lower right corner and the message read: " Plugged in, not charging ". Being a new generation kid I immediately hopped on google to try and solve this. After reading through a dozen articles about said problem I did the following (please note that I have a sealed in battery - stupid I know): " Uninstalled the battery drivers, restarted the pc, plug out and plugged in the AC charger.

But to no avail. Immediately saddened by the fact because I knew my laptop was getting old (14 months) and the battery wasnt the best (2,5 Hours) but this problem appeared so suddenly that I couldnt help but feel a bit cheated. I went to bed early and decide to leave the charger in my laptop for the night. Surprisingly it charged as I woke in the morning and as a test I left it to charge with no activity for the entire day. But as luck would have its way it stopped charging in the afternoon.
