Hi can anyone help me? I have a Dell Latitude C840, it takes a week to charge a battery, the computer recognises any battery i insert into any charging bay. Ive got 3 new batterys and a new 90 watt power supply and my original old 90 watt power supply. In the past it seems to have charged batterys about 3 times then the battery stops working.I the batterys dont get over heated or anything.Any ideas anyone? Thanks Dave Cheshire.
