XP Patch (Q306676) Direct3D Hibernate/Screen Saver
- The Computer Cannot Enter Standby or Hibernate If a Direct3D-Based Screen Saver Is Running (Q306676)
SYMPTOMS
If the 3D Flowerbox, 3D Flying Objects, 3D Pipes, 3D Text, or another Direct3D-based screen saver is running in Windows XP, the computer may be unable to enter standby or hibernation by using the timer in Power Management properties. Windows XP supports the ability to turn off the monitor or hard disks by using the Power Management timer with OpenGL (3D) screen savers running. This issue is not video adapter-dependent.
Hard Disk Performance Is Slower Than You Expect (Q308219)

This behavior may occur in the following situation:
You use Small Computer System Interface (SCSI) hard disks in the computer.
-and-
The hard disks are formatted as NTFS.
Note: If you are not severely affected by this problem, Microsoft recommends that you wait for the next Windows XP service pack that contains this fix. You must contact Microsoft Product Support Services to obtain the fix
