Power Management Setup - NEC Versa LXi Service And Reference Manual

Power Management Setup

If your Versa LXi system ships with the Windows 98 operating system, the Advanced
Configuration and Power Interface (ACPI) controls most power management functions through
the Power Management Properties screen in Windows. For details about ACPI power
management, see the section, "Managing System Power," later in this chapter. The BIOS Power
Management Setup screen is described next. Please note that the following definitions apply in
the Windows 95 environments and that some do not apply under Windows 98 with ACPI, as
noted. Use SystemSoft's PowerProfiler to manage power in the Windows NT environment.
Access the PowerProfiler icon on the Windows NT taskbar.
Use the Power Management Setup to balance high performance and energy conservation.
