Enabling SpeedStep™ Technology
SpeedStep technology controls your computer'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.
Windows Vista automatically sets Intel Speedstep technologies in the Dell
Recommended, Balanced, and Power Saver power plans. It is disabled in the
High Performance power plan.
