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 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 certified 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.
