Toshiba Satellite Laptop Review

I had the same problem with mine; try using a program to monitor the temp while you're using it, and see if the temp goes any higher shortly before it shuts off. Mine never did, and I found out the problem was not overheating but rather the outlet I had it plugged into. The outlets at our house have all been tested, and the laptop should work on them all equally, however there is only 1 that it never has any problems with. (I've never had any problems with outlets while traveling, tho.) If you normally use your laptop while it's plugged in, try experimenting with diff. outlets in your home and see if the spontaneous shutdown continues. Give it at least a 30 min break each time it shuts off.
