Troubleshooting
■ To switch the image to the notebook screen, press fn+f4:
❏ On most notebook models, when an optional external
display device, such as a monitor, is connected to the
notebook, the image can be displayed at any time on
the notebook screen, the external display, or on both the
notebook screen and the external display simultaneously.
When you press fn+f4, the image is switched among the
notebook, one or more external display devices, and
simultaneous display.
❏ On some notebook models, the function of fn+f4 is
determined by the software you are using. For information
about the fn+f4 functions on your notebook, refer to the
hotkeys section of the Hardware and Software Guide,
which is located on the Notebook Documentation CD.
Is Software Functioning Abnormally?
If your software becomes unresponsive or responds abnormally:
■ Restart the notebook:
❏ In Windows XP Home:
Select Start > Turn Off Computer > Restart.
❏ In Windows XP Professional:
Select Start > Turn Off Computer > Restart > OK. (On
your notebook, the Turn Off Computer button may be
called the Shut Down button, depending on your network
connections).
If you cannot restart the notebook using these procedures,
refer to the next section,
“Is the Notebook Unresponsive?”
■ Run a virus scan. For information about using the antivirus
resources on your notebook, refer to
“Protect the Notebook
from Viruses,” in the “Next Steps” chapter.
