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.
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 strain-relief loop, not on the cable itself.
Some cables have a connector 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.
To avoid damaging the computer, perform the following steps before you begin working inside the computer.
1 Turn off your computer.
NOTICE:
To disconnect a network cable, first unplug the cable from your computer and then unplug it from the
network wall jack.
2 Disconnect any telephone or telecommunication lines from the computer.

power button to ground the system board.

NOTICE:
Before touching anything inside your computer, ground yourself by touching an unpainted metal surface,
