Always followinstallation instructions closely.• If you use an extension power cable with your AC adapter, ensure that the total ampere rating of the productsplugged in to the extension power cable does not exceed the ampere rating of the extension cable.• Do not push objects into air vents or openings of your computer. Doing so can cause fire or electric shock byshorting out interior components.• Do not store your computer in a low-airflow environment, such as a carrying case or a closed briefcase, while thecomputer is turned on. Restricting airflow can damage the computer or cause a fire.• Keep your computer away from radiators and heat sources. Also, do not block cooling vents. Avoid placing loosepapers underneath your computer; do not place your computer in a closed-in wall unit or on a bed, sofa, or rug.• Place the AC adapter in a ventilated area, such as a desk top or on the floor, when you use it to run the computeror to charge the battery. Do not cover the AC adapter with papers or other items that will reduce cooling; also, donot use the AC adapter inside a carrying case.• The AC adapter may become hot during normal operation of your computer. Use care when handling the adapterduring or immediately after operation.• Do not allow your portable computer to operate with the base resting directly on exposed skin for extendedperiods of time. The surface temperature of the base will rise during normal operation (particularly when ACpower is present). Allowing sustained contact with exposed skin can cause discomfort or, eventually, a burn.• Do not use your computer in a wet environment, for example, near a bath tub, sink, or swimming pool or in a wetbasement.• If your computer includes an integrated or optional (PC Card) modem, disconnect the modem cable if anelectrical storm is approaching 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 performmaintenance or reconfiguration of this product during an electrical storm. Do not use your computer during anelectrical storm unless all cables have been disconnected and the computer is operating on battery power.• If your computer includes a modem, the cable used with the modem should be manufactured with a minimumwire size of 26 American wire gauge (AWG) and an FCC-compliant RJ-11 modular plug.• Before you open the memory module cover, fan covers, or Mini PCI card cover on the bottom of your computer,disconnect all cables from their electrical outlets and disconnect the telephone cable.• If your computer has both a modem RJ-11 connector and a network RJ-45 connector, which look alike, make sureyou insert the telephone cable into the RJ-11 connector, not the RJ-45 connector.• PC Cards may become very warm during normal operation. Use care when removing PC Cards after theircontinuous operation.• Before you clean your computer, disconnect the computer from the electrical outlet.
