[Save the anti-compaq comments.. don't want to hear it!] I have a Presario R3000 laptop. I am having an issue where the AC plug just falls out on its own; or it could be plugged in, yet switches back and forth between AC and battery because the plug is loose. I need to get this fixed. It's driving me nuts. Anyone know the fix? Would it be replacing the ac plug? Something I can do myself or should I bring it to Best Buy or something? I called Compaq, but they were completely worthless.
