The computer screen is blank
If the screen is blank but you have not turned off the computer, one or more
of these settings may be the cause:
●
The computer may be in the Sleep state or in Hibernation.
To exit Sleep or Hibernation, briefly press the power button.
Sleep and Hibernation are energy-saving features that turn off the
display. Sleep and Hibernation can be initiated by the system while the
computer is on but is not in use, or when the computer has reached a
low battery level. To change these and other power settings, select
Start > Control Panel > System and Maintenance > Power
Options
.
●
The computer may not be set to display the image on the computer
screen.
To transfer the image to the computer screen, press fn+f4.
On most models, when an optional external display, such as a monitor,
is connected to the computer, the image can be displayed on the
computer screen or the external display, or on both devices
simultaneously. When you press fn+f4 repeatedly, the image
alternates among the computer display, one or more external displays,
and simultaneous display on all devices.
Software is functioning abnormally
If the software is unresponsive or responds abnormally, follow these
suggestions:
●
Restart the computer by clicking
Start
, clicking the arrow next to the
Lock button, and then clicking
Restart
.
If you cannot restart the computer using this procedure, refer to the
next section, “The computer is turned on but not responding.”
●
Run a virus scan. For information about using the antivirus resources
on the computer, refer to “Protecting the computer from viruses” in
Chapter 4.
