Display problems
Here are some typical display problems and their solutions:
The screen is blank.
Display Auto Off may have gone into effect. Press any key to
activate the screen.
You may have activated the instant password feature by
pressing
Fn and F1 simultaneously. If you have registered a
password, press any key, type the password and press Enter . If
no password is registered, press any key. The screen
reactivates and allows you to continue working.
If you are using the built-in screen, make sure the display
priority is not set for an external monitor. To do this, press
Fn
and F5 simultaneously (once). If this does not correct the
problem, press Fn and F5 simultaneously again to return the
display priority to its previous setting.
HINT: Holding the Fn key and pressing the F5 key several
times will advance you through the display options.
If you are using an external monitor:
❖ Check that the monitor is turned on.
❖ Check that the monitor’s power cord/cable is firmly
plugged into a working power outlet.
❖ Check that the cable connecting the external monitor to
the computer is firmly attached.
