The green light is on...but the screen remains black. I was trying to connect to a public Wi-Fi spot when my IE and Firefox broswers froze. I tried restarting the computer several times, nothing happened. I then tried shutting it down...and nothing happened. I closed the top and then opened it again a few minutes later...again nada, no go. I bought it from a Microcenter in Westbury, NY...and I think it's under limited warranty, since I bought it two weeks ago (brand new). What do I do at this point? I run online business and I can't rely on library computers 24/7.
