Problems starting up the computer
The computer doesn’t start up.
m The battery may need recharging. Plug the power cord into a working
outlet and then plug the power adapter into the computer. Let the battery
recharge for a few minutes.
m Check that the power cord is plugged into a working outlet. If it’s plugged
into a power strip, make sure the power strip is turned on. The power
adapter should get warm after being plugged in for 10 minutes. If it is
cold, make sure the adapter is securely plugged in and attached to the
power cord.
m The screen brightness may be turned down. Adjust the brightness control
located at the base of the screen, in the center.
m Make sure the battery is properly seated in its compartment.
m If none of these measures helps, you may need to reset the computer.
The method of resetting you should always try first is to press the
Command (x), Control, and Power keys simultaneously. If the computer
does not start up, connect the power adapter (if it is not already connected)
and press the reset button (marked with the icon I) on the back panel.
