6 Processor performance controls Ä CAUTION: To prevent overheating, do not obstruct vents. Use the computer only on a hard, flat surface. Do not allow another hard surface, such as a printer, or a soft surface, such as pillow, thick rugs, or clothing, to block the airflow. Overheating can damage the computer and reduce processor performance. ✎ In some cases, a computer may operate at a higher speed on external power than on battery power. If the battery power is extremely low, the computer may attempt to conserve power by reducing processor speed and graphics performance. Windows XP enables you to manage the processor performance controls by selecting a power scheme. The processing speed can be set for optimal performance or for optimal power conservation. 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 computer is plugged into external power or is running on battery power. Each power scheme for external power or battery power sets a specific processor state. Power 6-1
