I have a Thinkpad Z60m, single core, 2 GHz. Everything original except the memory, increased to 1.5 GB. in my case, i think the GPU heats up pretty badly... it is very hot where I think the video card is located. I've posted to both mobile@ and acpi@ under the subject of 'Management of Thermal' with my woes while on the latest 6.2 before 7 went into Beta1. Since my upgrade to 7 i've had no major issues with heat. The emails i've posted previously show the settings i have been using, as well as whatever I had done in knoppix to manage the speed of the fan. cheers, B _________________________ {Beto|Norberto|Numard} Meijome "Caminante no hay camino, se hace camino al andar" Antonio Machado I speak for myself, not my employer.
