Gateway laptop battery shows plugged in, not charging

I have a gateway laptop running on a Windows Vista Operating System. Yesterday is displayed “Plugged in, not charging” on my battery. To make things work out for me I have tried various ways in which it should not display me the same error on my battery. I think it can be because of my Windows Vista which I am running on my laptop. I had also tried uninstalling and installing my device twice but it did not worked out for me. Please help me in getting rid of this situation. Your reply would be very helpful and appreciated.

Now I guess it should be working fine.

I had the same problem with my laptop for this purpose I gave them as it was in warranty. After that they changed the battery and then the motherboard, also, they had updated its bios but it was the same as the problem still persists. But they taught to change my battery. By doing that it seems my system was working fine. Also, it was not given the “Plugged in, charging not” on the battery. And by that it made me happy.

After a long search I came to from this web site which says you have to update your BIOS so that your system must work fine. BIOS resolved the issue where the battery did not charge fully. It took me just 5 minutes to download a 2MB file. After it I can say it worked out fine for me. Finally, it was not the hardware or software issue which had done problem to most of the system but you just simply need to update your BIOS.
