1 Before Working on Your Computer This document provides procedures for removing and installing the components in your computer. Unless otherwise noted, each procedure assumes that: • You have performed the steps in "Before Working on Your Computer" on page 9. • You have read the safety information that shipped with your computer. • When replacing a component, you have already removed the original, if installed.
CAUTION: When you disconnect a cable, pull on its connector or on its pull-tab, not on the cable itself. Some cables have connectors 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.
