I own a Toshiba Tecra A7 notebook. I've got it on April 2008 and I was pretty satisfied by it.

Unfortunately, after I got back home last September I started having problems with the notebook. After some time with intense computation (video encoding, compiling software, etc..) with 100% CPU the system simply shut down.

So, I started investigating the problem. The reason, confirmed by the thermal sensors, was pretty obvious: overheating. Some times the CPU passed 100°C.
