Managing System Power
In the Windows 98/2000 environment, the NEC Versa manages its power resources using the
Advanced Configuration and Power Interface (ACPI) while the system is powered on using AC
or battery (DC) power. ACPI enables the operating system to manage the power given to each
attached device and to turn off a device when not in use.
In the Windows NT environment, the NEC Versa also uses SystemSoft’s PowerProfiler to
manage power resources and to balance performance with battery conservation. Access
PowerProfiler via its taskbar icon or via the Programs menu.
Take advantage of the opportunity to manage power on the system to:
!
Minimize battery drain.
!
Preserve the life of the NEC Versa.
!
Save time. For example, when returning from a urgent call or meeting, you don’t have to
reboot, just press the Power button to resume system operation.
Windows 98 Power Management Properties
In Windows 98, most ACPI power management settings are controlled through Windows Power
Management Properties, not through the BIOS Setup utility, unless otherwise noted. To access
Windows 98 Power Management Properties, go to Start, Settings, Control Panel, and double
click Power Management.
The Power Management Properties features are as follows:

Windows 98 Power Schemes
Use the Power Schemes options to define the appropriate Power scheme for the system, and to
set timeouts for standby, LCD panel, and hard disk. Define parameters for the system when
running under AC (plugged in) or DC (running on batteries) power.
