Power Management Setup
Your NEC Versa uses the Advanced Configuration and Power Interface
(ACPI) which enables the operating system to manage the power given
to each attached device and to turn off a device when not in use. In
addition, ACPI enables manufacturers to develop computers that
automatically power up with a touch to the keyboard.
The Power Management Setup menu lets you balance high performance
and energy conservation using parameters including the following.
T
ACPI Aware OS — Specifies whether or not the system will boot to
an ACPI-aware operating system.
T
Power Switch Button — Lets you use the Power button as a power
switch or a sleep button.
T
LCD Suspend/Resume — Allows you to lock the power switch
setting when the LCD panel is closed.
T
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 usually
disabled. If you enable this parameter, the system automatically
activates the power management profile you set, even when AC
power is used.
T
Power Savings Level — Lets you choose one of four levels of power
management.
High Perform provides the greatest system performance with only
minimal power conservation.
Longest Life provides the maximum amount of power savings.
Off disables power management and all device timeouts.
Custom lets you define your own power management
configuration by selecting values for specific device timeouts.
