Display problems
When I turn on the
computer, nothing appears
on the screen. •
If the screen is blank, make sure that:

the power cord is plugged into a working electrical outlet.
- The computer power is on. (Press the Power button again
for confirmation.)

If these items are properly set, and the screen remains blank,
have the computer serviced.

while the computer is on. •
Your screen saver or power management may be enabled.

Fn + F2 to confirm whether the backlight of the LCD
screen has been turned off.
