The Dell XPS 15 is a high end computer in general, it has 9 cell battery (the backup time will be approximate 3 hours with Dell recommended power plan) Varies depending on operating conditions, to help you with specific information please let me know the exact model number of the system.

I have a Dell XPS M1530, I love this laptop but the thing is, my computer freezes and when I do a hard restart the screen doesn't come on (stays black). I searched the web for a solution and I found that it was the video card was the problem.

My warranty expired 2 months ago and the laptop will not charge or recognize the power supply. It does start up and run fine on a full battery. The battery does not charge when the power supply is connected. The power supply (cord) does work on another machine, so that is not the issue.
