Safety Instructions

Use the following safety guidelines to protect your computer from potential damage and ensure your personal safety.

ALIENWARE Aurora AAR4 - Safety Instructions - 1

WARNING: 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 dell.com/regulatory_compliance.

ALIENWARE Aurora AAR4 - Safety Instructions - 2

CAUTION: To avoid damaging the computer, ensure that the work surface is flat and clean.

ALIENWARE Aurora AAR4 - Safety Instructions - 3

CAUTION: To avoid damaging the components and cards, handle them by their edges and avoid touching pins and contacts.

ALIENWARE Aurora AAR4 - Safety Instructions - 4

WARNING: Disconnect all power sources before opening the computer cover or panels. After you finish working inside the computer, replace all covers, panels, and screws before connecting to the power source.

CAUTION: Only a certified service technician is authorized to remove the computer cover and access any of the components inside the computer. See the safety instructions for complete information about safety precautions, working inside your computer, and protecting against electrostatic discharge.
CAUTION: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the metal at the back of the computer. While you work, periodically touch an unpainted metal surface to dissipate static electricity, which could harm internal components.
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.

The procedures in this document may require the following tools:

  • Small Phillips screwdriver
