About two months ago the battery in my laptop was no longer recognized.  No errors.  The battery still charges and I can run for about 1 1/2 hours, but the battery shows as "Not Present" in the Power Meter.  At first the Task Bar would show that I was still plugged in to AC power even after I had disconnected (it no longer does this).  When I run on battery the battery light on the laptop glows orange, and I have no idea how much battery life I have.  When I plug back in to AC power it doesn't show that it's charging the battery (yet it is).  I'm running Windows XP SP3, and this is the original Dell battery.

Thanks for any help you guys can provide!
