If the standby indicator is off, your computer is in hibernation mode or
power-off state. Connect the ac adapter to the computer; then press
power button to resume operation.
If the system still does not return from standby mode, your system may
stop responding and you cannot turn off the computer. In this case, you
need to reset the computer. If you have not saved your data, it may be
lost. To reset the computer, press and hold the power button for 4 seconds
or more. If the system is still not reset, remove the ac adapter and the
battery.
Problem:
Your computer does not enter standby or hibernation mode.
Solution:
Check whether any option has been selected that would 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.
Solution:
For Windows 98:
The generic CD-ROM or DVD-ROM driver for Windows 98 accesses the
internal CD-ROM 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 enable the computer to enter standby mode, do the following:
1. Click Start.
2. Move the pointer 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 Settings 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 , edit the
configuration information in the registry as follows:
HKEY_LOCAL_MACHINE\SYSTEM\
CurrentControlSet\Services\Cdrom\
Autorun: 0x1 > Autorun:
