10Before You Begin Before Working Inside Your Computer 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 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. 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 your 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: 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: 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. CAUTION: To avoid damaging the computer, perform the following steps before you begin working inside the computer. 1Ensure that the work surface is flat and clean to prevent the computer cover from being scratched. 2Turn off your computer (see Turning Off Your Computer on page 9) and all attached devices. CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the cable from the network device. 3Disconnect all telephone or network cables from the computer. 4Press and eject any installed cards from the 8-in-1 media card reader. 5Disconnect your computer and all attached devices from their electrical outlets. 6Disconnect all attached devices from your computer. book.book Page 10 Friday, April 13, 2012 2:02 PM
