Embedded Numeric Keypad

As you work, you may want to use the embedded numeric keypad (see Figure 1) to enter numbers in spreadsheet or financial programs. The embedded numeric keypad shares some of the keys on your computer's keyboard. The number and symbol characters are marked to the right on these keys. To activate the embedded numeric keypad, press <Num Lk>. The Num Lock indicator lights up.

Figure 1. Embedded Numeric Keypad

Some key combinations can be used whether the keypad is off or on.

NOTE: On an external keyboard, use <Scroll Lock> with the appropriate keys if the External Hot Key option is enabled in the System Setup program.

Use the numeric keypad combinations in Table 1 to enable and disable several numeric keypad functions.

<Fn> + up arrow	Incrementally increases brightness.
<Fn> + right arrow	Decreases contrast, which has no effect on an active-matrix display. (Not supported on DSTN screens.¹ )
<Fn> + left arrow	Increases contrast, which has no effect on an active-matrix display. (Not supported on DSTN screens.¹)
<Fn><F5> (not supported on Dell Latitude CPx H-Series/J-Series)	Toggles the computer's display between regular video mode and reverse video mode (white on black). This key combination works only if the computer is in text mode; it has no effect if the computer is running a graphical operating system or application program. (Not supported on the Dell Latitude CPx H-Series/J-Series portable computer with ATI Mobility M1 video controller.)
<Fn><F7>	Toggles the computer’s display between expanded mode and regular video mode.
<Fn><F8>	Switches the video image to the next display in the following sequence: the display, an external monitor, or both displays simultaneously. This key combination may not be supported under certain conditions.²
<Fn><d>	Turns off the display. This key combination may not be supported under certain conditions.³

¹Contrast cannot be changed on an active-matrix (thin film transistor [TFT]) display.

To use key combinations on an external keyboard, enable the External Hot Key option in the System Setup program and use <Scroll Lock> instead of <Fn>.

² True Simul-mode (the ability to simultaneously display video of the same content and resolution on both the computer display screen and the external display) is not supported if the system is booted to MS-DOS®, using a full-screen MS-DOS session under a Microsoft® Windows® operating system, or the ATI Mobility M1 video driver is not loaded. This limitation may also be noted in operating systems other than Microsoft Windows.

³ Certain key combinations may not function with the Advanced Configuration and Power Interface (ACPI) or may require configuration with the Power Management Properties window in the Control Panel. See Power Management Settings.
