I have a Dell Inspiron E1505 Laptop. Just yesterday, I was using it on battery, which was at full charge when I took it off AC Power. About a month ago, I had the battery replaced, because my old one provided me with a charge lasting only 30 minutes, and for a college student, it is not easy to drag around the power adapter everywhere I go. It has been running fine until today. From what I can tell, the light that goes on when the battery is charging does not come on when the computer is on, but when it's off it comes on. Everything I've checked says my laptop battery is "performing normally" and what not. I highly doubt It's the outlet that I am using, as I've been using it for 3 days with no problem. The last thing I have to check is my power pack, but I don't just have another one lying around. Any help is appreciated.
