When maximum performance is selected, the processor operates at full (100%) speed. When battery optimized mode is selected, the processor operates at approximately 80% of the maximum performance mode.

Optimizing Processor Speed

(available on select models)

Some Presario Notebook models use the Pentium® III Processor featuring Intel® SpeedStep™ Technology. This technology gives you the capability to optimize your Notebook’s processor speeds based on the power source in use.

The default SpeedStep icons for each power source are listed below:

The checkered flag icon in the system tray on the Windows taskbar indicates External AC Power and Maximum Performance.

The non-checkered flag icon in the system tray on the Windows taskbar indicates Battery Optimized Performance.

To change the setting for either power source, AC or battery, right-click the SpeedStep icon in the System Tray and select either

Battery Optimized Performance or Maximum Performance.
