Battery "plugged in, charging", but NOT charging.

Hi,

I recently upgraded from Windows Vista Home Premium to Windows 7 Home Premium.  With Vista, my battery performed very admirably and I never had any issues.  As soon as I upgraded to Windows 7, I now encounter the following problem:

When I mouse over the battery icon in the system tray, it says "19% available (plugged in, charging)".  However, the battery isnot charging at all.  The little battery level animation stops, and, even though the system seems tothink it is charging my battery, it is not.  When I first installed the new OS, the battery would charge to 69% with the same problem, then it went up to 75% for about 1 week before plummeting so that, now, my battery charge ceiling is 19%, which, as you can imagine, lasts about 15 minutes on battery power.

After several redundant and unhelpful communications with Microsoft, I thought perhaps someone on this board might have experience with this issue or suggestions on what I might try.

Please note this is NOT the seemingly frequent problem that some people have with the battery saying "plugged in, not charging", as my system specifically says the battery IS charging when it is not.

It took me some time to even get Microsoft to agree to troubleshoot the problem as they insisted it was because my battery is a bit old.  However, this happens with both batteries I own, using either charger that I have, and, as I said before, it ONLY started right when I clean installed Windows 7.

Thanks in advance for any help!

Ryan
