CHAPTER 4: INSTALLING AND REPLACING COMPONENTS
58
Before Working Inside Your Computer
Use the following safety guidelines to help protect your computer from potential damage and
to help to ensure your own personal safety.
WARNING: Before working inside your laptop, read the safety information that
shipped with your computer. For additional safety best practices information, see the
Regulatory Compliance Homepage at www.dell.com/regulatory_compliance.
CAUTION: Handle components and cards with care. Do not touch the components or
contacts on a card. Hold a card by its edges. Hold a component such as a processor by
its edges, not by its pins.
CAUTION: Only a certied service technician should perform repairs on your computer.
Damage due to servicing that is not authorized by Dell is not covered by your
warranty.
CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding
strap or by periodically touching an unpainted metal surface (such as a connector on
the back of the computer).
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.
