I am having an issue which is regarding the battery problem in the HP Pavilion dv4000 laptop. The battery of my device is not charging. I have also gone through the HP diagnostic but it tell that battery is working properly. The AC power is on but the blue LED light is not coming. I am worried about the system that this is the issue of the battery or caused by any other thing. So please let me know about the same. Thank you.
