Traveling with your computer
This topic provides information to help you work with your computer when you are traveling.
Use the following travel tips to travel more confidently and efficiently with your computer.
• When your computer goes through the x-ray machines at airport security stations, it is important to keep
your eyes on the computer at all times to prevent theft.
• Consider bringing an electrical adapter for use on an airplane or automobile.
• If you carry an ac power adapter, detach the ac cord from it to avoid damaging the cord.
Travel tips on airplanes
If you carry your computer onto an airplane, observe the following tips:
• Be careful about the seat in front of you on airplanes. Angle your computer display so that it does not get
caught when the person in front of you leans back.
• When taking off, remember to turn off your computer or put it to hibernation mode.
• If you intend to use your computer or wireless services (such as Internet and Bluetooth), check with the
airline for restrictions and availability of services before boarding the airplane. If there are restrictions on
the use of computers with wireless features on the airplane, you must abide by those restrictions.
