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

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.
