SYMPTOMS
When you view the Power Management tool in Control Panel, the Turn Off Monitor option may be missing.



CAUSE
This issue can occur if your video adapter and your video adapter driver do not support Advanced Configuration and Power Interface (ACPI) power management. The video adapter driver must be ACPI compliant and properly map the control methods which are read by the Acpi.sys file to construct the options that are displayed in the Power Management tool in Control Panel. Note that this problem can occur if you are using an out-of-date video adapter driver, or if the ACPI Control Method description block was improperly implemented.



RESOLUTION
To work around this issue, contact the manufacturer of your video adapter to inquire about the availability of a Windows 2000 specific video adapter driver, or a driver that supports all of the features of ACPI power management.
