My P.O.S. gateway m520 which I bought about a year and a half ago has lost its power. I'm guessing it's the AC connecter pin on the back, as I've tried several different adapters. I've called a handful of different repair shops, some of the big national ones and some local ones, and they either don't want to touch it or they'll charge $300 to open it up. That's also how much it would cost to send it back to Gateway and there's no chance I'm giving them any more money. Does anyone have any suggestions that would help me out? I don't want to drop that kind of money on this machine because it's been nothing but problematic since day 1. I've considered disassembling it myself but that's proven to be more difficult than I had anticipated. I don't really care about the computer at this point, but if anyone has any suggestions I would greatly appreciate it. Thanks for your help.
