Arrrggghhh! My Acer 5102 laptop is 3 days old. All I've done so far is install the eTrust security software. I used my laptop this morning, and it worked fine. I then turned it off properly. Now the computer will not start up at all, even when plugged in. Last I checked, battery was 75% full. I've tried turning it on with the AC plugged into the wall, and then with just the battery. Nothing seems to work. Help!! Does this sound like maybe it's just a lemon?
