The computer does not
enter suspend mode as
set by the timer under
Windows 98 or Windows
NT.
For Windows 98:
The Windows 98 generic CD-ROM or DVD-ROM driver accesses the internal
CD-ROM drive or DVD-ROM drive every 3 seconds to see if a CD-ROM is
inserted in the CD-ROM drive or DVD-ROM drive. This prevents your computer
from entering suspend mode even after a timeout.
To prevent this from occurring, do the following:
1. Double-click on My Computer, Control Panel, and System.
2. Click on the Device Manager tab.
3. Click on the
+
mark of CD-ROM.
4. Double-click on the CD-ROM or DVD-ROM name.
5. Click on the Setting tab.
6. Remove the check mark from Auto insert notification.
Windows 98 no longer detects the CD-ROM or DVD-ROM insertion
automatically.
For Windows NT:
The computer does not enter suspend mode through the timer if you enable the
CD-ROM AutoRun feature. To enable the timer in this situation, edit the
configuration information in the registry as follows:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdrom\
Autorun: x1 → Autorun:
134
