Ergonomic Computing Habits - Dell Inspiron 3800 Reference And Troubleshooting Manual

•
When you move your computer between environments with very different
temperature and/or humidity ranges, condensation may form on or within the
computer. To avoid damaging the computer, allow sufficient time for the moisture
to evaporate before using the computer.
NOTICE: When taking the computer from low-temperature conditions
into a warmer environment or from high-temperature conditions into a
cooler environment, allow the computer to acclimate to room
temperature before turning on power.
•
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 with a soft cloth dampened with water rather than with
liquid or aerosol cleaners.
•
Clean the display with a soft, clean cloth and commercial window cleaner that
does not contain wax or abrasives. Apply the cleaner to the cloth; then stroke the
cloth across the display in one direction, moving from the top of the display to the
bottom. If the display contains grease or some other contaminant, use isopropyl
alcohol instead of commercial window cleaner.
•
If your computer gets wet or is damaged, follow the procedures described in
Chapter 3, "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.)
