This file contains up-to-date information for your HP notebook PC on these topics:
> default infrared mode
> DVD and video file playback
> Fn hot keys on an external keyboard
> hibernate mode
> system goes to standby even when standby timeout is disabled

You can find additional current information about your computer on the HP notebook Web site,
www.hp.com/notebooks.

Default infrared mode

In the BIOS Setup utility, infrared (IR) communication is by default disabled. When you enable IR
communication, the IR mode selected by default is FIR (Fast Infrared).

Fn hot keys on an external keyboard

When using combination hot keys (shortcut key sequences) on an external keyboard—which is
equivalent to using the Fn key on the HP notebook keyboard--use the Ctrl and Alt keys on the left
side of the external keyboard.

Hibernate mode

Hibernate mode occurs automatically when battery power reaches a critically low level. It is
possible to change the battery power settings, however, HP does not recommend that you change
the defaults. Changing the default values could cause your unit to not suspend properly and could
result in loss of data.

Using Enhanced Video and Dual Monitors

Standard video drivers are installed on your Notebook for various settings of screen area and
colors, as well as for screen zoom capabilities.

To use two monitors in dual mode

You can use two monitors with your Notebook, either in dual mode, effectively expanding your screen real
estate, or in simultaneous mode, displaying the same screen twice.

The LCD monitor that is part of the Notebook is the primary display (Monitor 1), and a second CRT
monitor attached to the rear video port is the secondary display (Monitor 2). You can also switch from one
monitor to the other (using only one at a time) by pressing Fn+F12.

To enable the dual monitor for a 14 inch display.

1. Click Start, Settings, Control Panel.

2. Double-click Display.

3. Select the Settings tab.

4. Position the second monitor to the right or left of your Notebook display to match your monitor
location.

5. Select each monitor and set the colors and screen area to the desired values. The following
settings support dual display mode:

6. Click the Start Button and select Shut down.

7. Connect the monitor cable from the monitor to the VGA port on the rear of the Notebook or on
the port replicator.

8. Connect the monitor to a power source and turn it on.

9. Press the blue power button to turn on the Notebook. Windows will detect the second monitor
and attempt to load the proper display driver. Follow the onscreen instructions.

10. Click Start, Settings, Control Panel, Display, Settings Tab. Position the second monitor to the
right or left of your Notebook display to match your monitor location.

11. Make sure that the option “Extend my Windows desktop onto this monitor” is checked.

Here are some other limitations to be aware of as you choose your monitor settings:

• The sum of the video memory used by both monitors must be less than the total video memory
size. Your Notebook comes with 4-MB memory installed.

• Monitor 1 has to be in the same resolution as the panel size. For example, if the panel is
800?600, the resolution selected for the Monitor1 must be exactly 800?600 in order to enable
dual display mode.

• Monitor 1 can be set to 256 colors or High Color (16 Bit), not True Color (24 bit), since
Virtual Refresh can be supported only in 256 color and High Color (16 Bit) modes. Monitor 2
can be set to 256 colors or High Color (16 Bit) only.

• Monitor 1 and Monitor 2 cannot both be in 256-color mode.

• Settings cannot be changed on Monitor 2 if DirectDraw is enabled—for example, if video is

playing—since the display driver cannot reallocate the display memory for dual display
support.

• Under dual display mode, only the software cursor can be used. There is no hardware cursor
available under Virtual Refresh mode.

• Dual display mode is not available if you are currently in a special mode from the LynxEM
video control panel settings, such as Rotation or Stretch.

Games that use the DirectDraw API cannot run in dual display mode. You will be prompted to
disable Monitor 2 before running the game.
