I have this problem with my laptop, which is a hp ze5575sr.Everytime I plug the ac plug into the back of the computer, it keeps going in and out. Like one second its charging the battery and the next I have to wiggle the plug where its plugged at.I know its not the cable,just bought a new one,damn them things are expensive!! Anyway does anyone know what the problem could be and if it is the plug inside the computer how hard would it be to fix? Taking this thing apart looks like a real B--CH.Thanks for any help.

You will need a professional to fix a problem like that i expect.
