Q304797

-

The information in this article applies to:


 * Microsoft Windows XP Home Edition
 * Microsoft Windows XP Professional
 * Microsoft Windows XP 64-Bit Edition

-

SYMPTOMS
After you configure your computer to use an OpenGL screen saver, your computer may not enter Standby mode even though you specified the System Standby power scheme in the Power Options tool in Control Panel.

CAUSE
This behavior can occur if the OpenGL screen saver starts before the specified time elapses for the Standby mode to start.

STATUS
This behavior is by design.

MORE INFORMATION
Advanced Configuration and Power Interface (ACPI) puts the computer into 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 Standby mode is reset.
