Power Conserving Battery Power Using the battery conservation procedures and settings described in this section extends the time that a battery pack can run the tablet PC from a single charge. Conserving Power As You Work To conserve power as you use the tablet PC: ■ Turn off wireless connections and exit modem applications when you are not using them. ■ Turn off the local area network (LAN) device when you are not using the LAN connection. You can turn off the LAN device with LAN Power Save mode by disconnecting the network cable. For more information, see the "Using LAN Power Save Mode" section in this chapter. ■ Disconnect external devices you are not using that are not connected to an external power source. ■ Stop or remove a PC Card you are not using. For more information, refer to Chapter 6, "Drives." ■ Use the fn+f9 and fn+f10 hotkeys to adjust screen brightness as you need it. ■ Use optional powered speakers instead of the internal speakers, or use the volume buttons to adjust system volume as you need it. ■ Turn off a device connected to the S-Video-out jack by using the fn+f4 hotkey or by turning off support for the device in Windows. ■ Run the tablet PC on external power while formatting a diskette. ■ If you leave your work, initiate standby or hibernation or shut down the tablet PC.
