The built-in display is blank
when you turn on your Life-
Book notebook.
(continued)
The notebook is set for
an external monitor
only.
Pressing [F10] while holding down the [Fn] key allows you to
change your selection of where to send your display video. Each
time you press the keys you will step to the next choice. The
choices, in order are: built-in display only, external monitor only,
both built-in display and external monitor.
The display angle and
brightness settings are
not adequate for your
lighting conditions.
Move the display and the brightness control until you have ade-
quate visibility. Pressing either the [F6] or [F7] keys while holding
down the [Fn] key also allows you to change the brightness level
of the display.
The notebook turned on
with a series of beeps and
the built-in display is blank.
POST has detected a
failure that doesn’t allow
the display to operate.
Contact your support representative.
The display goes blank by
itself after you have been
using it.
The notebook has gone
into Video timeout,
Standby, or Save-to-
Disk mode because you
have not used it for a
period of time.
Press any button on the keyboard, or move the mouse to restore
operation. If that fails, push the Power/Suspend/Resume button.
Check your power management settings, in the Power Options
control panel.
The power manage-
ment timeouts may be
set for very short inter-
vals and you failed to
notice the display come
on and go off again.
Press any button on the keyboard, or move the mouse to restore
operation. If that fails, push the Power/Suspend/Resume button.
(The display may be shut off by Standby Mode, Auto Suspend or
Video Timeout)
The application display
uses only a portion of your
screen and is surrounded
by a dark frame.
The application doesn’t
support native pixel res-
olution and display
compression is
enabled.
Display compression gives a clearer but smaller display for appli-
cations that do not support native pixel resolution. You can fill the
screen but have less resolution by changing compression set-
tings.
