Hello all! recently I noticed that my sister's laptop was getting very very hot when it sat on my lap, she had also complained that it just turned off on her without warning... so I decided to run Coretemp and Everest to test processor temperature.(It is an AMD Athlon X2... not sure what it runs at.) It seemed to idle around 75-80 Celsius and under 100% load it peaked at 115 ! I realize that laptops run a lot hotter than desktop but I think that is ridiculously hot...am I right?

Anyway... Her laptop is still under warranty and I was wondering what is the best way to prove to future shop that it is running that hot. Should I give them a printout of a stress test or something like that? Or should I just bring it in to them and tell them what I think is wrong and let them test it.

Thanks for the help!
