CPU Power Management
These options control the feature that automatically cuts the
system processor’s external clock speed down to around
8␣ MHz during periods of inactivity (to reduce power
consumption) and restores it to 25/33␣ MHz again when needed.
This option group is greyed-out if CPU Power Management is
disabled.
The check boxes allow you to select what events or activity
will wake the processor.
In the Inactivity Timer text box, specify the period of inactivity
after which the system processor will be slowed down.
