I have a Dell Vosto 1000. I have a replacement AC adapter as well as a replacement battery. The AC adapter will not charge the battery. When I take the battery out, the laptop stays powered on via the AC adapter. (hence, it is recognizing the adapter). I have heard that some replacement adapters will only power on the Dell laptop but will not charge the battery, however, when I plug the same adapter into another Dell laptop, the adapter charges it. I have also tried several different batteries, and several different AC adapters. Even a Dell factory AC adapter. The issue seems to be with the laptop itself. Has anyone else experienced this issue, and if so, any solutions?
