Query: No Battery Life - BAD OVERHEATING PROBLEM

This is a great piece of machinery, if you can get it to run for more than 20-20 minutes before it overheats and shuts down. When used on my desk, would last about an hour without overheating, but the battery is almost dead by then anyway. Good idea, not enough research before production. Video and Audio are THE BEST for a laptop though. Even Toshiba admits that there is a problem now (they wouldn't before). Mine was a newer model, purchased about a month ago.... Better Processor, and included an external USB 1.44 floppy too. If you can stand buying a fan to blow on it all the time, good machine, but I give it 1 STAR because a laptop/notebook should be able to be used as one, not have to be on a desk with extra fans. Oh, and Toshiba reps are AWFULL when they're at fault, but great when just need a little help.
