The Benefits of Intel® SpeedStep™ Technology
Intel SpeedStep® technology is the latest feature in the Intel line of mobile Pentium® III processors that allows the processor to be switched to a lower processor speed.
SpeedStep technology is not currently applicable to the Intel Celeron® processor line.
Decreasing the processor speed can extend the amount of time available for battery operation before requiring that the battery be recharged or replaced. One can set a SpeedStep enabled notebook computer to automatically switch to battery-optimized mode when the notebook is not connected to an AC power source or set the computer to remain in maximum performance mode at all times.
Accessing Intel® SpeedStep™
There is an Intel SpeedStep® utility (launched by double-clicking the SpeedStep icon located in the system tray) that allows you to configure these modes. (Figure 1)

The following Dell™ portable computers currently provide Intel SpeedStep® support:
The Inspiron 8000 and Latitude D800 computers do not provide support for the Intel software applet in Microsoft® Windows®, but they do have a battery-optimized mode and a performance mode setting in the BIOS (System Setup).
