4-4 Using the Operating System and Utilities
Transmeta LongRun Utility
The Crusoe processor that powers your NEC Versa notebook is equipped with the
LongRun power management utility. This utility automatically adjusts the clock speed
and voltage of the processor based on the needs of the application. If the system is in an
idle state, or doing processing that doesn’t require faster clock speeds, it automatically
lowers to 300MHz. If the system is completing more demanding tasks, it adjusts up to
full 600MHz. The ability to lower the processor speed results in longer battery life for
your NEC Versa system.
The LongRun utility is a tool that allows you to override these automatic adjustments
by the processor. You can
! Force the processor to stay at the lower 300MHz speed to preserve the battery
when you need the system to run for a long time without an AC source.
Forcing the battery to run at lower speeds slows some applications but extends
the battery life by hours.
! Force the processor to stay at the higher 600MHz speed when system speed is
necessary, or when the system is running on an AC power source.
