To help avoid possible damage to system boards, wait five seconds after turning off the
computer before removing a component, removing a system board, or disconnecting a
peripheral device from the computer.
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 disconnecting the cable. As you pull connectors
apart, keep them evenly aligned to avoid bending any connector pins. Also, before connecting
a cable, make sure both connectors are correctly oriented and aligned.
Do not attempt to service the system yourself except as
explained in this user's guide. Follow installation and
troubleshooting instructions closely.
