Preparing to Work Inside the Computer
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 System Information Guide 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: 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 scratching the
computer cover.
2. Save any work in progress and exit all open programs.
3. Turn off the computer and all attached devices.
