Preserving connections. If you have active network connections, or if you have
any SCSI devices connected, use the ac adapter and press the On/Off key to stop
the OmniBook. These connections and devices are disconnected if you stop the
OmniBook any other way.
However, Windows 95 can restore network connections and SCSI devices when you
turn on the OmniBook. For a different operating system, you may have to reboot the
OmniBook or restart the operating system to restore them.
If you want to know more about what happens when you stop the OmniBook, you
can check the following table.
Power States after Stopping the OmniBook
Method of Stopping Power State Condition
On/Off key
(with ac adapter connected)
Display Off Powered/operating state. The computer
looks off, but only the display, keyboard, and
mouse are turned off. Network and SCSI
devices are maintained. Everything
continues at turn-on.
On/Off key
(with no ac adapter)
Suspend Low-power/stopped state. Everything is off or
in a low-power state. Network and SCSI
devices are off. Everything resumes
operating at turn-on. For Windows 95, SCSI
changes are detected at turn-on.
CTRL+ALT+On/Off key Off Low-power/stopped state. Everything is off or
in a low-power state (battery charges if ac
adapter is connected). Computer reboots at
turn-on.
The Start button provides two commands that stop the OmniBook.
• Suspend changes the OmniBook to the Suspend state.
• Shut Down (Shut down the computer) changes the OmniBook to the Off state.
If you plug in the ac adapter while the OmniBook is stopped, battery-charging
components are activated, but the OmniBook stays in the same power state. On the
other hand, if you unplug the ac adapter while the OmniBook is in the Display Off
state, it changes to the Suspend state.
In addition, Advanced Power Management (APM) provides several automatic power-
saving features that affect the power state. You can adjust settings in the
System
Configuration Utility to control features such as this:
• If the OmniBook is running on battery power and there’s no activity for a short
period of time, it automatically stops by changing to the Suspend state.
To reset and restart the OmniBook
If Windows or the OmniBook gets stuck and stops responding (and you can’t recover
in Windows), you can reset the OmniBook and restart Windows.
