CAUTION: Do not operate your portable computer for an extended period of time with the base resting directly on your body. With extended operation, heat can potentially build up in the base. Allowing sustained contact with the skin could cause discomfort or, eventually, a burn.
• Do not attempt to service the computer yourself. Always follow installation instructions closely.
• Do not carry a battery in your pocket, purse, or other container where metal objects (such as car keys) could short-circuit the battery terminals. The resulting excessive current flow can cause extremely high temperatures and may result in damage from burns.
• Be sure that nothing rests on your AC adapter's power cable and that the cable is not located where it can be tripped over or stepped on.
• Place the AC adapter in a ventilated area, such as a desk top or on the floor, when you use it to run the computer or to charge the battery. Do not cover the AC adapter with papers or other items that will reduce cooling; also, do not use the AC adapter while it is inside a carrying case.
• Do not use your computer in a wet environment, for example, near a bath tub, sink, or swimming pool or in a wet basement.
• Do not push objects into air vents or openings of your computer. Doing so can cause fire or electric shock by shorting out interior components.
• Use only the AC adapter and batteries that are approved for use with this computer as indicated in this document. Use of another type of battery or AC adapter may risk fire or explosion.
Before you connect the computer to a power source, ensure that the voltage rating of the AC adapter matches that of the available power source:
- 115 V/60 Hz in most of North and South America and some Far Eastern countries such as South Korea and Taiwan
- 100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
- 230 V/50 Hz in most of Europe, the Middle East, and the Far East
To help prevent electric shock, plug the AC adapter and external device power cables into properly grounded power sources. These cables are equipped with 3-prong plugs to help ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use an extension cable, use a 3-wire cable with properly grounded plugs.
If you use an extension cable with your AC adapter, ensure that the total ampere rating of the products plugged in to the extension cable does not exceed the ampere rating of the extension cable.
To remove power from the computer, turn it off, remove the battery, and disconnect the AC adapter from the electrical outlet.
If your computer includes an integrated or optional (PC Card) modem, disconnect the modem cable during an electrical storm to avoid the remote risk of electric shock from lightning via the telephone line.
To help avoid the potential hazard of electric shock, do not connect or disconnect any cables or perform maintenance or reconfiguration of this product during an electrical storm.
PC Cards may become very warm during normal operation. Use care when removing PC Cards after their continuous operation.
Do not dispose of batteries in a fire. They may explode. Check with local authorities for disposal instructions.
When setting up the computer for work, place it on a level surface.
When traveling, do not check the computer as baggage. You can put your computer through an X-ray security machine, but never put your computer through a metal detector. If you have the computer checked by hand, be sure to have a charged battery available in case you are asked to turn on the computer.
• When traveling with the hard drive removed from the computer, wrap the drive in a nonconducting material, such as cloth or paper. If you have the drive checked by hand, be ready to install the drive in the computer. You can put the hard drive through an X-ray security machine, but never put the drive through a metal detector.
• When traveling, do not place the computer in overhead storage compartments where it could slide around. Do not drop your computer or subject it to other mechanical shocks.
• Protect your computer, battery, and hard drive from environmental hazards such as dirt, dust, food, liquids, temperature extremes, and overexposure to sunlight.
• 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 an external 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.
• 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, see page 42 for instructions. If you drop or damage the computer, see page 43. If, after following these procedures, you confirm that your computer is not operating properly, contact Dell (see page 75).
