The display is blank when
you turn on your notebook. Something is pushing on the
Closed Cover switch. Clear the Closed Cover switch. (See Figure on page 8

The display angle and bright-
ness settings are not adequate
for your lighting conditions. Press the [Fn] + [F7] keys repeatedly until you have
the desired brightness.
The LifeBook 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
combination of 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 power management time-
outs may be set for very short
intervals and you failed to
notice the display come on
and go off again. Press any button or key on the keyboard, or move
the mouse to restore operation. If that fails, push the
Power and Suspend/Resume button. (The display
may be shut off by Standby mode, Auto Suspend or

does not allow the display
to operate. Contact your support representative.
Your system display won’t
turn on when the system is
turned on or when the
system has resumed. The system may be password-
protected. Check the status indicator panel to verify that the
Security icon is blinking. If it is blinking, enter your
password.
The display goes blank by
itself after it is used. Something is pushing on the
Closed Cover switch. Check the Closed Cover switch. (See Figure on page
8 for location)
The notebook has gone into
Video timeout, Standby mode,
Suspend mode or Save-to-Disk
mode because you have not
used it for a period of time. Press any button or key on the keyboard, or move the
mouse to restore operation. If that fails, push the
power/suspend/resume button. Check your power
management settings, or close all applications and go
to Power Savings in the setup utility to adjust the
timeout values to suit your operation needs.
