7.1.3.3 Create a power plan
Besides the three preset power plans offered in Windows Vista, you can also customize your
own power plan. Select Create a power plan on the left pane of the Power Options window
to begin configuring your power settings.
7.1.4 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 enjoy better
performance, while slower speeds conserve more power.
In Windows Vista, the processor's performance level depends on the Power Scheme you
select (see 7.1.3 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, turning off the display, and turning off the
hard drive.
For example, the Windows Vista automatically changes SpeedStep modes depending on if
you are running the computer on AC power or batteries in order to prolong battery usage
while still providing optimal performance.
