Problem Cause and action
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
whether a CD-ROM is inserted in the CD-ROM drive or the 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 for CD-ROM.
6. Double-click the name of the CD-ROM or DVD-ROM.
7. Click the Settings tab.
8. Clear the Auto insert notification check box.
Windows 98 no longer detects a CD-ROM or a DVD-ROM automatically.
For Windows NT:
If you enable 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¥
