Travel tips
Use the following travel tips to travel more confidently and efficiently with your computer.
• Although it is safe to allow your computer to go 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 in 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 into an airplane, take note of the following tips:
• 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. If
necessary, disable wireless features before boarding.

caught when the person in front of you leans back.
• When taking off, remember to turn off your computer or put it into hibernation mode.
