Processor Performance Controls
(Select Models Only)
On select notebook 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 notebook 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 > Performance and
Maintenance > Power Options > Power Schemes tab.
The power scheme you select determines how the processor
performs when the notebook is connected to external power or
running on battery power. Each power scheme for external power
or battery power sets a specific processor state.
