Using SpeedStep Performance Modes

The Intel Pentium III with SpeedStep technology can enable an
automatic change in processor speed when the power source
changes between AC power and battery power.

Choosing a Performance Mode

The SpeedStep technology offers two preset performance modes:
In Maximum Performance mode, the processor runs at full
speed to provide maximum performance.
In Battery Optimized mode, the processor runs at a reduced
speed to provide an optimal balance between energy
conservation and performance.
The computer can run in either performance mode while it is
running on AC power or on battery power.

Changing a Performance Mode

In Windows 95 or Windows NT 4.0—Before the performance
mode changes from Battery Optimized to Maximum
Performance, you are prompted to restart the computer. The
restart selection on the prompt restarts the computer and returns
your work to the screen. It is not necessary to restart the computer
to change from Maximum Performance to Battery Optimized
mode.
In Windows 98 or Windows 2000 Professional—It is not
necessary to restart the computer to change performance modes.

Combining Performance Modes with Other Power Settings

In Windows 95, Windows NT 4.0, or Windows 2000
Professional—The SpeedStep technology performance modes
are independent of all power settings described in this guide or
your operating system documentation except the Custom
processor speed setting available on the Battery Conservation tab.
A Custom processor speed setting applies any time that the
computer is running on battery power.
In Windows 98—The SpeedStep technology performance modes
are independent of all power settings described in this guide or
your operating system documentation.
