I bought a replacement charger for my Dell XPS m1530. I think it is an universal one, but it wouldn't charge my battery!What should I do, should I buy a new one? Where can I buy a new one?
Dell Xps M1530 Replacement Battery
Those battery packs are meant to be used. The worst thing your grandfather could have done was to have it plugged in 24/7. I take mine off the charger at least a few times a month to let the battery drain off so it can get a fresh charge. At this point I'd look into replacing both battery and charger.
