36 Using the System Setup Program
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.
