Before Working Inside Your Computer
Use the following safety guidelines to help protect your computer from potential
damage and to help to ensure your personal safety. Unless otherwise noted,
each procedure included in this document assumes that the following
conditions exist:
• You have performed the steps in Working on Your Computer.
• You have read the safety information that shipped with your computer.
• A component can be replaced or--if purchased separately--installed by
performing the removal procedure in reverse order.
警告: Before working inside your computer, 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.
注意: Many repairs may only be done by a certified service technician. You should
only perform troubleshooting and simple repairs as authorized in your product
documentation, or as directed by the online or telephone service and support team.
Damage due to servicing that is not authorized by Dell is not covered by your
warranty. Read and follow the safety instructions that came with the product.
注意: 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.
注意: Handle components and cards with care. Do not touch the components or
contacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold
a component such as a processor by its edges, not by its pins.
注意: 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.
メモ: The color of your computer and certain components may appear differently
than shown in this document.
