Hi I have a Sony VGP-BPS21A laptop. It was working fine until I noticed that the battery wasnt charging. I heard the ac adaptor buzzing a bit so I figured the ac adaptor was on its last leg. So I ordered a new one. That didnt charge the battery. So I ordered a new battery. Still nothing charging.
I shut the laptop down, removed the Sony VGP-BPS21A battery(new and old) and tried running the laptop just off the old ac adaptor.
It boots up fine and is usable but I cannot get the battery to charge whether its the new Sony VGP-BPS21A battery /ac adaptor or the old ones.
Is there anything that possibly went on the board itself?????
I have been doing some research but cant find much answers out. I read some other people having the same problem but nothing answered in several forums I have read.

Hi, there!


I doubt it's a hardware issue.


I'd suggest that you go to bios, look for a "smart battery" feature there, and disable it. If you can't find it there, look for sony utilities in windows and try to do the same.
