Page 10 highlights

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 www.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 module 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. 1 Ensure that the work surface is flat and clean to prevent the computer cover from being scratched. 2 Turn off your computer (see "Turning Off Your Computer" on page 9). 3 If the computer is connected to a docking device (docked), undock it. See the documentation that came with your docking device for instructions. CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the cable from the network device. 4 Disconnect all telephone or network cables from the computer. 5 Press and eject any installed cards from the ExpressCard slot or the 3-in-1 Media Card Reader. 10 Before You Begin
