HP 80XL458 manual Optimizing Processor Speed, Charging the Battery

Page 31

The battery charges whether your Notebook is on or off.

It continues charging until the battery is fully charged or the AC power is disconnected.

The battery will lose its charge gradually if not used for a long time.

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.

Charging the Battery

To charge the battery, connect the battery to your Notebook and connect your Notebook to AC power. Leave your Notebook plugged into the electrical outlet until the Battery Charging icon glows green. This ensures that the

battery is fully charged.

Note: If you will not be using your Notebook for an

extended period of time, Compaq recommends that you unplug the electrical cord from the outlet and remove the battery while your Notebook is not

in use.

Optimizing Processor Speed

Some Presario Notebook models use the Pentium® III Processor featuring Intel® SpeedStepTM 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.
