Problem Action
The computer does not
enter suspend mode as
set by the timer under
Windows 98, Windows
95 or Windows NT.
For Windows 98 and Windows 95:
The Windows 98 and Windows 95 generic CD-ROM driver accesses the internal
CD-ROM drive every 3 seconds to see if a CD-ROM is inserted in the CD-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 My Computer, Control Panel, and System.
2. Click the Device Manager tab.
3. Click the + mark of CDROM.
4. Double-click the CD-ROM drive name.
5. Click Settings tab.
6. Remove the check mark from the Auto insert notification check box.
7. Click OK, and restart the computer.
Windows 98 and Windows 95 no longer detects the CD-ROM insertion automat-
ically.
For Windows NT:
The computer does not enter suspend mode by the timer if you enable the
CD-ROM AutoRun feature. To enable the Suspend Timer function in the registry,
do the following:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdrom\
Autorun: x1 Autorun:
The computer does not
enter hibernation mode
with the Fn+F12 key
combination.
Make sure the hibernation function is created. (See “Creating the Hibernation
Function” on page 55.)
To enter hibernation mode, stop the communication program, and then remove
the PC Card or turn off power to the PC Card slot using the Control Panel.
