I haven't read all the other responses, but my old laptop had major overheating problems. It got to the point where I couldn't scrap at all because after my first hour of scrapping it would unexpectedly shut down every few minutes, and the LO file would usually end up corrupt and unable to open even if I'd saved religiously. With the help of tech support I updated the bios, which helped, and then I went out and got one of the active cooling mats (active=with fans, passive=just a stand to elevate). It made a HUGE difference, and I used the laptop for another year or so with only an occassional problem. Just be prepared to replace the chill mat every few months--with hours a day use, they don't seem to last well.
