If the notebook is in Hibernation, you must restore from Hibernation before you can initiate Standby. To restore from Hibernation or resume from Standby, briefly press the power button. For more information about using Standby and Hibernation, refer to the "Power" chapter in the Software Guide on the Documentation Library CD. 2­6 Hardware Guide Pointing Devices and Keyboard Switching the Display (Fn+F4) The Fn+F4 hotkey switches the image between display devices connected to the external monitor connector or the S-Video jack on the notebook. For example, if an external monitor is connected to the notebook, pressing the Fn+F4 hotkey multiple times will toggle the image between the notebook display, the external monitor display, and a simultaneous display on both the notebook and the monitor. Most external monitors receive video information from the notebook using the external VGA video standard. The Fn+F4 hotkey can also toggle images between other devices receiving video information from the notebook. The following five video transmission types, with examples of devices that use them, are supported by the Fn+F4 hotkey: LCD (notebook display) External VGA (most external monitors) S-Video (televisions, camcorders, VCRs, and video capture boards with S-Video-in jacks) Viewing Battery Charge Information (Fn+F8) Press Fn+F8 to display charge information for all installed battery packs.

To use the keypad keys temporarily as standard keys while the keypad is on: Press and hold the Fn key to type in lowercase. Press and hold Fn+shift to type in uppercase. Using an External Keypad Most keys on most external keypads function differently when num lock mode is on than when num lock mode is off. For example: When num lock mode is on, most keypad keys type numbers. When num lock mode is off, most keypad keys function like arrow, page up, or page down keys. When num lock mode on an external keypad is turned on, the num lock light on the notebook turns on. When the num lock mode on an external keypad is turned off, the num lock light on the notebook turns off. Hardware Guide 2­11 Pointing Devices and Keyboard If the external keypad is connected, the internal keypad cannot be turned on. Enabling or Disabling Num Lock Mode as You Work To turn num lock mode on or off on an external keypad as you work, press the num lk key on the external keypad, not on the notebook. Enabling or Disabling Num Lock Mode at Startup To set the notebook to start up with a connected external keypad in num lock mode, set your preference in Computer Setup.

To start up an external keypad with num lock mode turned off, clear the field. 5. Press F10. 6. To save your preference and exit Computer Setup, select File > Save Changes and Exit, and then follow the instructions on the screen. Your preference is set as you exit Computer Setup and is in effect when the notebook restarts. 2­12 Hardware Guide 3 Battery Packs Running the Notebook on Battery Power When the notebook is connected to external AC power, the notebook runs on AC power. When a charged battery pack is in the notebook and the notebook is not connected to external power, the notebook runs on battery power. The notebook switches between AC power and battery power according to the availability of an external AC power source. For example, if the notebook contains a charged battery pack and is running on external AC power supplied through the AC adapter, the notebook will switch to battery power if the AC adapter is disconnected from the notebook. You can leave a battery pack in the notebook or in storage, depending on how you work. Keeping a battery pack in the notebook enables the battery pack to charge whenever the notebook is connected to external AC power and also protects your work in case of a power outage. On the other hand, battery packs in the notebook slowly discharge when the notebook is turned off and not connected to external power. For this reason, the primary battery pack is not shipped inside the notebook and must be inserted before the notebook can run on battery power. Hardware Guide 3­1 Battery Packs If the notebook will be unused and not connected to external power for 2 weeks or more, remove the battery pack and store it as described in "Storing a Battery Pack" to prolong its life. For more information about leaving your work, refer to the "Power" chapter in the Software Guide on the Documentation Library CD. compatible AC adapters and battery packs should be Onlythe notebook.
