Chapter 9: Routine care ■ Taking along a backup of your information. Keep the backup separate from the computer. ■ When traveling by air, carrying the computer as hand luggage, and do not check it in with the rest of your bags. Ä Avoid exposing a drive to magnetic fields. Security devices with magnetic fields include airport walk-through devices and security wands. The airport security devices that check carry-on luggage, such as conveyor belts, use X-rays instead of magnetism and do not damage a drive. ■ In-flight computer use is at the discretion of the airline. If you plan to use the computer during a flight, check with the airline in advance. ■ If the computer is unused and disconnected from external power for more than 2 weeks, remove the battery pack and store it separately. ■ If shipping the computer or a drive, use suitable protective packaging and label the package "FRAGILE." ■ If the computer has a wireless device or a cell phone device installed, such as an 802.11b/g device, a Global System for Mobile Communications (GSM) device, or a General Packet Radio Service (GPRS) device, the use of these devices might be restricted in some environments. Such restrictions might apply onboard aircraft, in hospitals, near explosives, and in hazardous locations. If you are uncertain of the policy that applies to the use of a particular device, ask for authorization to use it before you turn it on. ■ If you are traveling internationally: ❏ Check the computer-related customs regulations for each country 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. Å 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. Notebook Essentials 38
