Safety Instructions

Use the following safety guidelines to help protect your computer from

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

avoid bending any connector pins. Also, before you connect a cable, ensure that
both connectors are correctly oriented and aligned.

you begin working inside the computer.

1

Ensure that the work surface is flat and clean to prevent the computer
cover from being scratched.
