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.
NOTICE: To help allow the computer to maintain proper operating temperature, ensure that you do not place the
computer too close to a wall or other storage compartment that might prevent air circulation around the chassis.
NOTE: Before you install any devices or software that did not ship with your computer, read the documentation
that came with the device or software, or contact the vendor to verify that the device or software is compatible
with your computer and operating system.
You must complete all the steps to properly set up your computer. See the appropriate figures that follow
the instructions.
NOTICE: Do not attempt to operate a PS/2 mouse and a USB mouse simultaneously.

Before Working Inside Your Computer
Use the following safety guidelines to help protect your computer from potential damage and to help
ensure your own personal safety.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product
Information Guide.
CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a
card by its edges or by its metal mounting bracket. Hold a component such as a processor by its edges, not by
its pins.
NOTICE: Only a certified service technician should perform repairs on your computer. Damage due to servicing

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.
