Troubleshooting
The computer screen is blank
If the computer is on but the screen is blank: the computer
may be in Standby or in Hibernation, or the computer may
not be set to display the image on the computer screen.
Try the following suggestions to resolve the issue:
■
To exit Standby or Hibernation, briefly press the power
button.
Standby and Hibernation are energy-saving features that
can turn off the display. Standby and Hibernation can be
initiated by the system while the computer is on but not in
use, or when the computer has reached a low battery
level. To change these and other power settings, select
Start > Control Panel > Performance and Maintenance >
Power Options
.
■
To transfer the image to the computer screen, press
fn+f4
.
On most models, when an optional external display
device, 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
between the computer display, one or more external
display devices, and simultaneous display on all devices.
