Processor Performance Controls - HP Compaq NW8000 Software Manual

Processor Performance Controls

On select notebook models, Windows 2000 and Windows XP
support software that enables the user to control processor
performance. The central processing unit (CPU) speed can be set
for optimal performance or for optimal power conservation.
For example, the software can be set to trigger an automatic
change in processor speed when the power source changes from
external power to battery pack power, or when the notebook use
changes between active and idle.
Processor performance controls vary depending on the operating
system.
Windows 2000 Processor Controls
Windows 2000 notebooks with Intel Mobile processor with
SpeedStep technology enable the user to adjust the processor
speed. Intel SpeedStep functions independently from the power
management settings available through the operating system. You
must install SpeedStep separately.
Installing Intel SpeedStep (Windows 2000)
To install Intel SpeedStep technology, select Start > Programs >
Software Setup.
A setup wizard loads and displays a list of available applications.
Select Intel SpeedStep and follow the instructions on the screen.
When installation is complete, you will be prompted to restart the
notebook.
After you install SpeedStep, a tab is added to the Power Options
window, an icon is added to the taskbar, and SpeedStep is
automatically enabled.
The default SpeedStep settings are Maximum Performance for
external power and Battery Optimized mode for battery power.
For details on each setting, refer in this chapter to the
Performance Mode (Windows 2000)."
