NOTICE: Only a certified service technician should perform repairs on your computer. Damage due to servicing that is not authorized by Dell is not covered by your warranty.

NOTICE: When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and aligned.

To avoid damaging the computer, perform the following steps before you begin working inside the computer.

1 Turn off your computer if it is not already turned off.

Setting Up Your Computer

CAUTION: Before performing any of the procedures in this section, follow the safety instructions in

Product Information Guide.

NOTICE: If your computer has an expansion card installed (such as a modem card), connect the appropriate cable to the card, not to the connector on the back panel.

You must complete all the steps to properly set up your computer. See the appropriate figures that follow the instructions.

1 Connect the keyboard and mouse.

NOTICE: Do not attempt to operate a PS/2 mouse and a USB mouse simultaneously.
