CAUTION: The settings on the Alarms tab are preset for the Notebook to run at
optimum efficiency. Changing any of these settings may cause the Notebook to
function improperly. It is recommended that these settings be left at their default
values.
Rebooting After a Lockup
To reboot the Notebook when the keyboard is frozen, or when the screen is locked, press and hold
down the Power
Ÿ button for at least four seconds to perform a Manual Shutdown. Then restart the
Notebook with a single press of the Power
Ÿ button.
If the Notebook still does not recover, shut it down by pressing the Power
Ÿ button and holding it
down for four seconds. Then remove the battery and unplug the AC power for at least 30 seconds.
Reinsert the battery or reconnect AC power, and press the Power
Ÿ button once to reboot.
Recovering From a Loss of Electrical Power
Loss of electrical power causes the Notebook to turn off automatically. This may cause loss of data
because the Microsoft Windows operating system is not able to close all the files and programs
properly.
Loss of power may be caused by one of the following:
•
Interruption of electrical power service
•
Accidental disconnection of the power cord
