NOTICE: 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.
NOTICE: 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.
NOTICE: 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).
NOTICE: 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.
NOTICE: 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.
