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.
