2-16 System Configuration and Setup
!
Power Management Under AC — Specifies whether to enable power management features
when AC power is in use. When AC power is connected to your NEC Versa system, power
management is disabled (default setting). If you enable this parameter, the system
automatically activates the power management profile you set, even when AC power is
used.
!
Power Savings Level — Specifies one of four levels of power management.
— High Performance — provides good battery life and best performance with only
minimal power conservation. Use while traveling short distances.
— Longest Life — provides best battery life, the maximum amount of power savings, and
good performance. Use while traveling long distances.
— Off — disables power management and all device timeouts. Works well in an office
environment while powering your NEC Versa with AC power.
— Custom — lets you define power management levels and specific device timeouts
according to your own needs and present environment. Custom lets you set the
following timeouts.
Custom Timeout Options
Option Definition
CPU Speed Control Sets CPU performance at one of four levels.
Hard Disk Timeout Sets the time delay before your hard disk powers

system from suspend. Designates the time parameter in five minutes increments. (Not
applicable in Windows 98/2000 with ACPI.)
!
Intel SpeedStep™ Technology — Optimizes CPU performance when the system is powered
under AC or by battery.
