OpenGL Screen Saver Prevents Power Management Standby Mode

ID: Q227279

The information in this article applies to:

Microsoft Windows 2000 Advanced Server
Microsoft Windows 2000 Datacenter Server
Microsoft Windows 2000 Professional
Microsoft Windows 2000 Server

SYMPTOMS

When you configure your computer to use an OpenGL screen saver and the System Standby feature in Advanced Power Management (APM), your computer may not start the Standby mode.

CAUSE

This issue can occur if the OpenGL screen saver starts before the time you configured for the Standby mode to start has elapsed.

STATUS

This behavior is by design.

MORE INFORMATION

Advanced Configuration and Power Interface (ACPI) puts the computer in the Standby mode only after the CPU has been idle for the specified period of time. When an OpenGL screen saver starts, the CPU is no longer idle and the ACPI timer for the Standby mode is reset.
