If the computer or an application locks up, or if the computer does not
respond when you press the Power button, you may need to restart the
computer.
The computer uses the configuration currently saved in flash memory
during the boot process. Try these methods, in order, to restart the
computer:
•
Reboot: Restarts the computer and goes through the initialization
process.
•
Cold boot: Preserves configuration and network settings, but does
not necessarily save cached disk data, which may result in data loss.
•
Clean boot: Completely erases the computer memory, including all
applications and data files, except those in the Flash File Store or
any removable storage.
You may need to restart the computer to correct conditions where an
application stops responding to the system.
•
Press the Power button and select Reboot from the menu.
If the computer seems to be locked up and does not respond to
keypresses, try a cold boot to reset the operating system.
Note: The computer may also cold boot if you change the battery
while the CN51 is in Suspend mode, or if you do not change the battery
quickly enough when the CN51 is in Hibernate mode.
1 Press and hold the Power button for at least 8 seconds. The
computer turns off.
2 Press the Power button again. The computer cold boots.
