Processor Performance Controls
On select tablet PC models, Windows XP supports software that
enables you 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 tablet PC use
changes between active and idle.
Processor performance controls are managed in the Power
Options window.
To access Windows XP processor performance controls, select
Start > Control Panel > Power Options > Power Schemes tab.
