CAUTION:

Before you begin any of the procedures in this section, follow the safety instructions in the Owner's Manual.

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. Read and follow the safety instructions in the Owner's Manual that came with the computer.

CAUTION:

To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of

your computer's electronic components. You can do so by touching an unpainted metal surface.

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 microprocessor by its edges, not by its pins.

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.

NOTICE:

To avoid damaging the computer, perform the following steps before you begin working inside the computer.
