If You Have Display Problems
If your computer is receiving power, but nothing appears on your display (such as light, text, or graphics) or
the display image does not appear as you would expect, try the following measures to resolve the problem:
1. If the display is blank, you may be in suspend or standby mode. Press the power button to resume from
suspend mode or standby mode. If the display is blank and the power light-emitting diode (LED) is on,
the display may have timed out. In this case, press any key on the keyboard or move the mouse to
resume normal operation.
2. If the low-battery light is blinking, connect the AC adapter to the computer or replace the battery.
3. Adjust the brightness.
4. If your computer is attached to an external monitor, press <Fn><F8> to switch the video image to the
display.
