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. On these keys, the number and symbol characters of the numeric keypad appear in blue to the right of the main keypad characters. 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 or not the keypad is activated.
 |
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.
Table 1. Embedded Numeric Keypad Key Combinations
| When Keypad Is On | Function |
| <Num Lk> | Toggles the embedded numeric keypad off |
| <Fn><key> | Temporarily disables the embedded numeric keypad; enables the lowercase characters/functions of the keyboard |
| <Fn><Shift><key> | Temporarily disables the embedded numeric keypad; enables the uppercase characters/functions of the keyboard |
| When Keypad Is Off | Function |
| <Num Lk> | Toggles the embedded numeric keypad on |
| <Fn><Shift><number key> | Temporarily enables a number or symbol key in the embedded numeric keypad |
|
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 key combinations in Table 2 to adjust the computer's display.
Table 2. Display Key Combinations
| Key Combinations | Function |
| <Fn> + down arrow | Incrementally decreases brightness. |
| <Fn> + up arrow | Incrementally increases brightness. |
| <Fn> + right arrow | Has no effect on your computer. Decreases contrast on passive-matrix displays; has no effect on active-matrix displays. |
| <Fn> + left arrow | Has no effect on your computer. Increases contrast on passive-matrix displays; has no effect on active-matrix displays. |
| <Fn><F5> * | 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. |
| <Fn><F7> | Toggles the computer’s display between expanded video 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. |
| <Fn><d>* | Turns off the display. |
* This key combination may not be supported by future operating systems.
|
NOTES: Contrast cannot be changed on an
active-matrix (thin film transistor [TFT]) display, such as the display in your computer.
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>. |
|
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 key combinations in Table 3 to activate or turn off the computer's power conservation features.
Table 3. Power Conservation Key Combinations
| Key Combinations | Function |
| <Fn><d>* | Turns off the display |
| <Fn><h>* | Turns off the hard-disk drive |
| <Fn><Esc>* | Activates suspend or standby mode |
| <Fn><a> or <Fn><q> on French keyboards |
Activates suspend-to-disk mode |
* This key combination may not be supported by future operating systems.
|
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 key combinations in Table 4 to change the computer's processing speed.
Table 4. Processing Speed Key Combinations
| <Fn><\> * | Switches between the microprocessor's maximum speed and a slower compatibility speed |
| <Ctrl><\> | In full MS-DOS® mode or in a full-screen DOS box, switches between the microprocessor’s maximum speed and a slower compatibility speed |
* This key combination may not be supported by future operating systems.
|
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 key combinations in Table 5 to adjust the computer's speaker volume and to enable and disable the speakers.
Table 5. Speaker Key Combinations
| Key Combinations | Function |
| <Fn><Page Up> | Increases the volume of the integrated speaker and the external speakers, if attached |
| <Fn><Page Dn> | Decreases the volume of the integrated speaker and the external speakers, if attached |
| <Fn><End> | Enables and disables the integrated speaker and the external speakers, if attached |
|
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 key combinations in Table 6 to access MS-DOS, open the System Setup program, and open the Battery Status screen of the System Setup program.
Table 6. System Function Key Combinations
| Key Combinations | Function |
| <Ctrl><Alt><Del> | Restarts (reboots) the computer in MS-DOS mode. In the Microsoft® Windows® 95, Windows 98, and Windows NT® operating systems, click the Start button and click Shut Down. |
| <Fn><F1>* | Opens the System Setup program. |
| <Fn><F3>* | Opens the Battery Status screen of the System Setup program. |
* This key combination may not be supported by future operating systems.
|
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. |
To eject the CD-ROM or DVD-ROM tray, press <Fn><F10>.
