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: 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).
CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the
cable from the network device.
3. Disconnect all telephone or network cables from the computer.
4. Disconnect your computer and all attached devices from their electrical outlets.
5. Press and hold the power button while the system is unplugged to ground the system board.
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.
