Switching the screen image

Press fn+f4 to switch the screen image among display devices connected to the system. For example, if a monitor is connected to the computer, pressing fn+f4 alternates the screen image from computer display to monitor display to simultaneous display on both the computer and the monitor.

Most external monitors receive video information from the computer using the external VGA video standard. The fn+f4 hotkey can also alternate images among other devices receiving video information from the computer.

The following video transmission types, with examples of devices that use them, are supported by the fn+f4 hotkey:

●LCD (computer display)

●External VGA (most external monitors)

●HDMI (televisions, camcorders, DVD players, VCRs, and video capture cards with HDMI ports)

●Composite video (televisions, camcorders, DVD players, VCRs, and video capture cards with composite-video-in jacks)

NOTE: Composite video devices can be connected to the system only by using an optional docking device.

Enabling/disabling the TouchPad (fn+f5)

Press fn+f5 to enable or disable the TouchPad.

Viewing battery charge information

Press fn+f9 to decrease screen brightness. Hold down the hotkey to decrease the brightness level incrementally.

Increasing screen brightness

Press fn+f10 to increase screen brightness. Hold down the hotkey to increase the brightness level incrementally.
