Traveling With Your Computer

or in an overhead storage compartment.
Travel Tips
NOTICE:
Do not move the computer while using the optical drive to prevent loss of
data.

• Consider disabling wireless activity on your computer to maximize battery
operating time. To disable wireless activity, use the wireless switch (see
"wireless switch" on page 25).

operating time (see "Configuring Power Management Settings" on
page 50).
• If you are traveling internationally, carry proof of ownership—or of your
right to use the computer if it is company-owned—to speed your passage
through customs. Investigate the customs regulations of the countries you
plan to visit, and consider acquiring an international carnet (also known as
a merchandise passport) from your government.
• Find out what type of electrical outlets are used in the countries you will
visit, and have appropriate power adapters.
• Check with your credit card company for information about the kinds of
emergency travel assistance it offers to users of portable computers.

turn on the computer.
