CONTROLLING THE VIDEO DISPLAY USING SPECIAL KEY COMBINATIONS

Special key combinations allow you to control the video screen display.
These key combinations activate software features built into the
computer.  The keys used are the [Fn] key in conjunction with either the
[F8], [F9], or [F10] function keys.  If you connect an external keyboard
that does not have a [Fn] key, you must use the [Ctrl] and [Alt] keys by
pressing them at the same time instead of the [Fn] key.  Press them and
the corresponding function key for the specific feature you want to
activate.

To control the video display, the three key combinations and their
functions are as follows:

a)  Press [Fn+F8] keys to switch back and forth between the notebook's
    LCD screen and an external monitor or dual scan (LCD and CRT used
    simultaneously).  When you turn off the computer, the system will
    default to the LCD screen the next time you turn the computer on,
    even if an external monitor is connected.

b)  Press [Fn+F9] to reverse the background and foreground screen.  If
    a mono-LCD is attached, the function of this hot key is to switch
    the display screen between a white character on the black background
    screen or a black character on the white background screen.  If color
    LCD is attached, this hot key does not work (the screen does not
    change).

c)  Press [Fn+F10] to stretch the screen display vertically.  In some
    display modes, the image displayed on the screen does not use the
    entire screen and some blank space is left at both the screen top
    and bottom.  Using this key combination will stretch the display
    vertically so the entry screen is filled.

    The keyboard option in setup has two settings, INSTALLED and NOT
    INSTALLED.  Both settings appear to have no effect on the keyboard
    detection on power up.  In other words no matter what the setting, if
    an external keyboard is detected on power up, the external functions
    and the system keyboard will not.

1.  If setup is set for Video Display External CRT, the LCD does not
    have an active display.  If the CRT is removed the LCD still will not
    have an active display.  The result is no video on the LCD. If the
    3900 boots into windows the [Fn] [F8] keys (to alternate video
    display) has no effect.

    Solution: After the HDD/FDD activity light goes out, press [ALT] [F4],
    wait 3 seconds, press enter, wait 3 seconds, press the [Fn] [F8] keys.
    At this point the LCD is active, the user can change setup, or
    continue working with out making changes to setup.

Note:
   A. If the unit is powered down with out changes to setup, the steps
      above will need to be repeated.

   B. If the unit does not boot into windows, press [Fn] [F8] after the
      HDD/FDD light goes out.

   C. If using the external keyboard, use the [CTRL] [ALT] key sequence
      to replace the [Fn] key.

   D. If there is a password being used on the 3900, wait approximately 10
      seconds after powering up the unit, type in the password, press
      <ENTER>, and continue with the above steps.
