Traveling with the computer
For best results, follow these traveling and shipping tips:
■ Prepare the computer for traveling or shipping:
1. Back up your information.
2. Remove all optical discs and all external media cards, such as digital cards and
ExpressCards.
Ä
CAUTION: To reduce the risk of damage to the computer, damage to a drive, or loss of
information, remove the media from a drive before removing the drive from a drive bay, and
before shipping, storing, or traveling with a drive.
3. Turn off and then disconnect all external devices.
4. 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, and do not check it in with
the rest of your bags.
Ä
CAUTION: 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 will
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.
