come on and off.
The system may be password-
protected.
A foreign object, such as a

serve power.

that fails, push the Power/Suspend/Resume button. (The display may be shut off
by Sleep Mode, Auto Suspend or Video Timeout)

blinking, enter your password.
Remove all foreign objects from the keyboard.
