“GENERAL AND ELECTRICAL SAFETY PRECAUTIONS“ on page 58 and
“DETAILED SAFETY, ENVIRONMENTAL, AND REGULATORY INFORMATION“ on
page 60. 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 notebook. 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.
