Power Processor Performance Controls 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 Properties dialog box. 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 is running on battery power. Each power scheme for external power or battery power sets a specific processor state. Hardware and Software Guide 2-17
