Compaq 800 Series Installation and operating instructions

MAXIMIZING BATTERY OPERATING TIME

The PresarioTM 800 with Intel Pentium III processor supports

SpeedStep Technology. This technology supports two

operation modes:

•Performance Mode—the processor runs at maximum

speed if the notebook is powered on while connected to

an AC power source

•Battery Optimized Mode—the processor runs at lower

speed to maximize battery operating time if the notebook

is powered on with a battery source

To automatically change the processor settings when

changing power sources (from AC to battery or battery to

AC) without rebooting the notebook, you must install the

SpeedStep application.

To install the SpeedStep application, follow these steps:

1. Double-click the SpeedStep icon on the Windows

desktop.

2. Follow the instructions on the screen.
