Query: Disappointing

This is a nice notebook -- when it works. Like many people with Toshiba laptops, this model has a problem where it shuts off when it feels like it. Sometimes it restarts, sometimes not. Within two months of having it, it had to be sent away for repair, and now, after being back for about 3 days, it is still shutting off for no reason.Research indicates there could be a cooling problem or a static problem. Toshiba is aware of these issues, and supposedly there is a lawsuit being brought against them because they refuse to address the issue.I'm going to try to get my money back, but I'm not hopeful.
