SpeedStep

Your notebook is equipped with SpeedStep technology to better manage power
consumption. It changes the processor speed to find the best balance between your
computing performance and power consumption needs. Higher speeds bring better
performance, but the slower speed conserves more power.
In Windows Vista, the processor's performance level depends on the Power Scheme you
select (see 6.2.2 Power Options Properties). You do not need to make any further
adjustments to set the performance level. Each preset power scheme has different time-out
settings for entering Sleep Mode, Hibernate Mode, shutting down the display, or turning off
the hard drive.
For example, the Windows Vista automatically changes SpeedStep Modes depending on
running the AC power or batteries in order to prolong the battery usage while still providing
optimal performance.
