SYMPTOMS
When you configure your computer to use an OpenGL screen saver and you have chosen System Standby in the Power Schemes selector on the Control Panel's Power Options tool, your computer may not start the Standby mode.



CAUSE
This behavior 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.

Additional query words: ACPI power management screensaver
