•When you disconnect a cable, pull on its connector or on its strain-relief loop, not
on the cable itself. As you pull out the connector, keep it evenly aligned to avoid
bending any connector pins. Also, before you connect a cable make sure both
connectors are correctly oriented and aligned.
•Handle components with care. Hold a component such as a memory module by
its edges, not its pins.
•When removing a memory module from the system board or disconnecting a
peripheral device from the computer, wait 5 seconds after turning off the
computer before removing the memory module or disconnecting the device
to help avoid possible damage to the system board.
•Before you clean your computer, turn it off, unplug it from its power source, and
remove the battery pack(s).
•Clean your computer and display with a soft cloth dampened with water rather
than with liquid or aerosol cleaners.
•If your computer gets wet or is damaged, follow the procedures described in
Chapter 3, “Basic Troubleshooting.” If, after following these procedures, you
confirm that your computer is not operating properly, contact Dell Computer
Corporation. (See Chapter 5, “Getting Help,” for the appropriate telephone
number.)
