So I have a Z580 laptop which has ONLY Ubuntu 12.04 installed,
It has a i3 Processor with Intel and Nvidia Cards and 4GB RAM,
The problem is even if I run no apps, It gets heated up?
I removed Windows 7 completely while Installing Ubuntu.....
BTW My Nvidia Card is a GeForce with Cuda
Can Somebody Please Help Me?
EDIT: I found out that installing drivers for your card is a solution but I installed NVIDIA Drivers from the additional driver menu, but I really don't feel any change....

Try adding these commands and keep the setting as conservative.

sudo apt-get install cpufrequtils cpufreqd 
sudo apt-get install indicator-cpufreq

Also install bumblebee for better control over your graphics card. Click here for more information
