Problem: Your computer does not enter standby or hibernation mode.
Solution: Check if any option has been selected to disable your computer
from entering standby or hibernation mode.
Problem: The computer does not enter standby mode as set by the timer
under Windows 98 or Windows NT.
For Windows 98:
The generic CD-ROM or DVD-ROM driver for Windows 98 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 standby mode even after a timeout. To prevent
this from occurring, do the following:
1. Click Start.
2. Move the cursor to Settings and Control Panel.
3. Click Control Panel, and then double-click System.
4. Click the Device Manager tab.
5. Click the + mark of CD-ROM.
6. Double-click the name of the CD-ROM or DVD-ROM.
7. Click the Setting tab.
8. Clear the Auto insert notification check box.
Windows 98 no longer detects the CD-ROM or DVD-ROM insertion
automatically.
For Windows NT:
If you have enabled the CD-ROM AutoRun feature, the computer does not
enter standby mode through the timer . To enable the timer in this situation,
edit the configuration information in the registry as follows:
HKEY_LOCAL_MACHINE\SYSTEM\
CurrentControlSet\Services\Cdrom\
Autorun: 0x1 > Autorun: 0
