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
