The battery in my Dell D420 shows no charge when the battery LED indicator is pressed. Additionally the battery light blinks orange 4 times then green and the sequence repeats. This didn't happen until I removed the battery this morning to look at the hard drive. Once I reinserted the battery these problems began. Just last night this battery was working fine holding a charge for almost 3 hours.
I upgraded the memory from 1GB to 2GB. Can't see how this could affect anything but I want to mention it just in case.
