CPU overheating Toshiba Satelite L300-1AQ
I installed Ubuntu (Ubuntu 9.10 - the Karmic Koala) on my laptop (Dual boot with Vista) When I boot in Ubuntu and after few minutes the temperature goes very high starting from 35 to 45 up to 72 within 15 minutes. The problem doesn't exist in Windows Vista. Can anybody help me with the issue please?? I'm new to linux so if you decided to help me please make it as simple as possible.
