Safety Instructions

Use the following safety guidelines to help protect your computer from potential damage

and to help ensure your personal safety.

WARNING: Before you begin, read the safety information that

shipped with your computer. For more safety best practices

information, see the Regulatory Compliance Homepage at

dell.com/regulatory_compliance.

WARNING: Only a certified service technician is authorized to

remove the computer cover and access any of the components

inside.

CAUTION: To avoid damaging the computer, ensure that the work

surface is flat and clean.

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 or thumb-screws that you must disengage before

disconnecting the cable. When disconnecting cables, keep them

evenly aligned to avoid bending any connector pins. When

connecting cables, ensure that the connectors and ports are

correctly oriented and aligned.

CAUTION: To disconnect a network cable, first unplug the cable from

your computer and then unplug the cable from the network device.

NOTE: Ensure that you remove the security cable from the security-cable slot,

if applicable.
