The Best Buy guys said they've been seeing quite a few Asus netbooks and laptops with this problem. It also 'blanks out' and goes either to the desktop or to some other Win program on its own. We thought we were hitting a key inadvertantly. It doesn't save what you were doing. Best Buy had to send it in to get fixed. That's 4 weeks without...good thing we have an extra laptop. Good thing it's still under warranty, too. I'm glad you got to the heart of the matter, Veteran. Another trip to complain and I'd have thrown it on the floor...and I'm not a violent person.
