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
