Searching for ways to reduce the heat generated by my laptop i found a nice applet that helps to reduce the heat and save battery life.

Depending on the CPU/Processor you have it may have a capability to set its own the cock speed according to the processor load. Mime for instance, a AMD X2, has 1600Mhz and 800Mhz, for surf at internet 800 Mhz is more then enough and extents bouth battery life and reduces the temperature of your computer.

• Right click on a free space on your taskbar or “panel”.
• Select “Add to Panel…”
• Select the applet “CPU Frequency Scaling Monitor”

This was tested in Ubuntu 9.10
