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.
❖ Try adjusting the contrast and brightness controls on the
external monitor.
❖ Press Fn and F5 simultaneously to make sure the display
priority is not set for the built-in screen.
The screen does not look right.
You can change the display settings by clicking a blank area of the
desktop with the secondary control button, then clicking
Personalize. This opens the Personalization window. Click
Windows Color and Appearance to choose the colors for the
screen. Click Display settings to choose the screen resolution.
The built-in screen flickers.
Some flickering is a normal result of the way the screen produces
colors. To reduce the amount of flickering, try using fewer colors.
