Just got off the phone with Acers customer service, and easily the rudest person that I've ever talked to in my life. After I told him that my machine wasn't powering up at all. He said it was a hardware issue. It was a course out of warranty, and it would cost $700 to fix it. The thing was less than 2 years old. Well I cracked the son of a b**** open in the back. Unplug the battery, started it and it came to life, pulled the AC put their battery cable back in, and it's alive. So if you have this completely dead power issue, try opening up the back and disconnecting the battery, don't let Acer customer support scare you, it might just be an easy fix. Good luck, and shame on Acer for having impatient, and condescending customer support.
