WORKAROUND
To work around this problem, use any other screen saver so that the computer can enter standby or hibernate.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
Advanced Configuration and Power Interface (ACPI) places the computer in standby only after the CPU has been idle for the specified period of time. When a 3D screen saver starts, the CPU is no longer idle, and the ACPI timer for standby is reset.

After applying the hotfix, the system will stop the 3D screen saver when monitor turns off. By doing so, the CPU of the system will be considered as idle so that the system can enter standby afterward. You may see the following symptoms after installing the fix:
 * The Power Management timer for standby is reset after the monitor turns off.
 * When you preview 3D screen saver, the system will not go into the Standby mode directly. Instead, the system will wake up from Preview, and then go into Standby when it times out.
 * If you set the monitor to turn off and the screen saver to start at the same time, the computer may not go into standby and hibernate modes.
