Safety Instructions 11
CAUTION: Safety Instructions
Use the following safety guidelines to help ensure your own personal safety and to help protect your computer and
working environment from potential damage.
SAFETY: General
Do not attempt to service the computer yourself unless you are a trained service technician. Always follow
installation instructions closely.
If you use an extension power cable with your AC adapter, ensure that the total ampere rating of the products
plugged 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 by
shorting out interior components.
Do not store your computer in a low-airflow environment, such as a carrying case or a closed briefcase, while the
computer 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 loose
papers 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 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 inside a carrying case.
The AC adapter may become hot during normal operation of your computer. Use care when handling the adapter
during or immediately after operation.
Do not allow your portable computer to operate with the base resting directly on exposed skin for extended
periods of time. The surface temperature of the base will rise during normal operation (particularly when AC
power 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 wet
basement.
If your computer includes an integrated or optional (PC Card) modem, disconnect the modem cable if an
electrical 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 perform
maintenance or reconfiguration of this product during an electrical storm. Do not use your computer during an
electrical 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 minimum
wire 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 sure
you 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 their
continuous operation.
Before you clean your computer, disconnect the computer from the electrical outlet. Clean your computer with a
soft cloth dampened with water. Do not use liquid or aerosol cleaners, which may contain flammable substances.
