    TITLE:  Windows 95 APM, Suspend and CD-ROM

    ISSUE

       Computer systems configured with CD-ROM drives do not perform the
       Suspend To Disk or RAM function when Power Management is enabled
       under Windows 95.

       This issue may affect all systems that use Windows 95 Advanced
       Power Management.

    BACKGROUND

       The activity caused by Windows 95 continually polling the IDE
       controller looking for CD-ROM drive activity prevents Suspend To
       Disk from ever taking place.

    ACTION

       To use the Suspend To Disk function under Windows 95 Power
       Management, disable the CD-ROM "Auto Play" function in Windows 95
       as follows:

       1. While in Control Panel, click on the System icon, then
          on the Device Manager tab.

       2. Double-click on the CD-ROM icon, then double-click on
          the icon for the specific CD-ROM drive installed in
          the system.

       3. Click on the Settings tab, then uncheck the "Auto
          Insert Notification" box.

       4. Click OK.

       These steps prevent Windows 95 from polling the IDE controller.
