Hung Computer
If the computer does not turn off when you press the power button, the computer may be hung. Press and hold the power button until the computer turns off
completely (this process may take several seconds). If the computer is hung and the power button fails to function properly, unplug the AC power cable from
the computer, wait for the computer to completely stop running, and plug in the AC power cable. If the computer does not restart, press the power button to
restart the computer.
Connecting an IEEE 1394 Device
IEEE 1394 is a digital interface that can move large amounts of data between computers and peripheral devices. IEEE 1394 is ideal for use with multimedia
devices because it speeds the transfer of data and large files, which enables a computer to connect directly to devices such as digital video cameras.
Your computer provides a standard IEEE 1394 connector as an add-in card. For information on adding a card, see " Installing a Card ."
TAPI
Your computer supports TAPI-compliant modem cards using the standard TAPI connector (the green connector labeled MODEM or TELEPHONY). If your modem
supports voice features, you can connect your modem to the TAPI connector and then use your audio speakers and microphone as an answering machine or
speakerphone. The microphone carries your voice into the computer and then through the TAPI system board connector to your modem card. The caller's voice
enters through the modem card to the TAPI system board connector and then out to the speakers. You can also use this configuration to record and play
audio files over the telephone by using third-party software.
Installing a TAPI-Compliant Modem Card
1. Shut down the computer through the Start menu.
2. Ensure that your computer and attached devices are turned off. If your computer and attached devices did not automatically turn off when you shut
down your computer, turn them off now.
3. Disconnect any telephone or telecommunication lines from the computer.
4. Disconnect your computer and all attached devices from electrical outlets, and then press the power button to ground the system board.
5. Open the computer cover .
6. Install the TAPI-compliant modem card:
a. Connect the 4-pin TAPI cable to the TAPI system board connector.
To locate the TAPI connector on the system board, see " System Board Components ."
b. Connect the other end of the cable to the TAPI connector on the modem card.
To locate the TAPI connector on the card, see the documentation for the card.
7. Close the computer cover .
8. Reconnect the computer and devices to electrical outlets, and turn them on.
the computer may result in data loss. Use the power button
to shut down the computer only if the operating system is
not responding.
