Can I configure power management settings?A feature of the operating system-directed power management system in Windows 2000 Professional is the ability to customize certain power settings using the user interface. There is a Power Options icon in Control Panel that exposes these settings and enables the creation of custom power schemes that you can implement in specific circumstances.
See "Using the Power Management Interface" in this chapter.
How do I troubleshoot power management problems?In order for Windows 2000 Professional to manage power, the devices and device drivers in the computer must be ACPI-compliant. When devices and device drivers are not ACPI-compliant, unexpected behavior can occur. Using troubleshooting information, you can often determine which devices and device drivers are causing problems.
