Servicing Your Computer - Full Off Mode
If you need to install or replace components in your system, you must turn the computer off
completely. Follow the instructions above for properly putting the computer into Off mode,
unplug from the outlet, and remove the battery (see battery section for instruction on removing
battery).
Rebooting After a Lockup
Occasionally you may encounter a frozen keyboard or a locked screen. To reboot your computer
(as if from a cold start) press and hold down the Power Button for at least four seconds, which
will cause a manual shutdown. Then, restart it with a single press of the Power Button. If it still
doesn't recover, press the Power Button and hold it for four seconds to shut it down, then,
remove the battery or unplug the AC power for at least 30 seconds. Reinsert the battery or
reconnect AC power and press the Power Button once to reboot.
