vSafety InstructionsAs you use your computer, observe the following safety guidelines:• Do not attempt to service the computer yourself. Always follow installationinstructions closely.• Do not carry a battery pack in your pocket, purse, or other container where metalobjects (such as car keys) could short-circuit the battery terminals. The resultingexcessive current flow can cause extremely high temperatures and may result indamage from burns.• Be sure that nothing rests on your AC adapter’s power cable and that the cable isnot 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, whenyou use it to run the computer or to charge the battery. Do not cover the ACadapter with papers or other items that will reduce cooling; also, do not use theAC adapter inside a carrying case.• Do not use your computer in a wet environment, for example, near a bathtub,sink, or swimming pool or in a wet basement.• Do not push objects into air vents or openings of your computer. Doing so cancause fire or electric shock by shorting out interior components.• Use only the AC adapter and batteries that are approved for use with thiscomputer as indicated in this document. Use of another type of battery pack orAC adapter may risk fire or explosion.• Before you connect the computer to a power source, ensure that the voltagerating of the AC adapter matches that of the available power source:— 115 volts (V)/60 hertz (Hz) in most of North and South America and someFar 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 peripheral power cablesinto properly grounded power sources. These cables are equipped with 3-prongplugs to help ensure proper grounding. Do not use adapter plugs or remove thegrounding prong from a cable. If you must use an extension cable, use a 3-wirecable with properly grounded plugs.
