Enabling PowerNow!™ Technology

PowerNow! technology controls your system’s processor performance automatically, dynamically adjusting the operating frequency and voltage according to the task at hand. When an application does not require full performance, significant amounts of power can be saved. Performance is designed to still be responsive, with maximum processor performance being delivered when required, and automatic power savings when possible.

NOTE: PowerNow! support is dependent on the operating system and version used on your system.

To enable the PowerNow! feature, run the System Setup Program and enable the Demand-Based Power Management option on the CPU Information screen.

Additionally, for Microsoft® Windows® operating systems, you will need to install the PowerNow! driver to enable this feature. The driver is available on the Dell OpenManage Service and Diagnostic CD provided with your system, and at support.dell.com.
