- Back up your information to an external drive. - Remove all discs and all external media cards, such as memory cards. - Turn off and then disconnect all external devices. - Shut down the computer. ● Take along a backup of your information. Keep the backup separate from the computer. ● When traveling by air, carry the computer as hand luggage; do not check it in with the rest of your luggage. CAUTION: Avoid exposing a drive to magnetic fields. Security devices with magnetic fields include airport walk-through devices and security wands. Airport conveyer belts and similar security devices that check carry-on baggage use X-rays instead of magnetism and do not damage drives. ● If you plan to use the computer during a flight, listen for the in-flight announcement that tells you when you are allowed to use your computer. In-flight computer use is at the discretion of the airline. ● If you are shipping the computer or a drive, use suitable protective packaging and label the package "FRAGILE." ● The use of wireless devices might be restricted in some environments. Such restrictions might apply aboard aircraft, in hospitals, near explosives, and in hazardous locations. If you are uncertain of the policy that applies to the use of a wireless device in your computer, ask for authorization to use your computer before you turn it on. ● If you are traveling internationally, follow these suggestions: - Check the computer-related customs regulations for each country or region on your itinerary. - Check the power cord and adapter requirements for each location in which you plan to use the computer. Voltage, frequency, and plug configurations vary. WARNING! To reduce the risk of electric shock, fire, or damage to the equipment, do not attempt to power the computer with a voltage converter kit sold for appliances. 24 Chapter 6 Maintaining your computer
