After Working Inside Your Computer

 

 

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 www.dell.com/regulatory_compliance.

 

CAUTION: 

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.

 

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: 

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.

 

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. 

NOTE:

 The color of your computer and certain components may appear differently than shown in this document. 

 

CAUTION: 

To disconnect a network cable, first unplug the cable from your computer and then unplug the cable from the network device.

 

CAUTION: 

To avoid damaging the system board, you must remove the main battery before you service the computer.

 

 

CAUTION: 

To guard against electrical shock, always unplug your computer from the electrical outlet before opening the display.

 

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: 

To avoid losing data, save and close all open files and exit all open programs before you turn off your computer.
