Special considerations
Follow the same special considerations as when traveling with the computer. In
addition, these tips are useful when traveling internationally:
•
When traveling in another country, check that the local AC voltage and the
AC adaptor power cord specifications are compatible. If not, purchase a
power cord that is compatible with the local AC voltage. Do not use
converter kits sold for appliances to power the computer.
•
If you are using the modem, check if the modem and connector is
compatible with the telecommunications system of the country you are

Securing your computer
Your computer is a valuable investment that you need to take care of. Learn
how to protect and take care of your computer.
Security features include hardware and software locks — a security notch
and passwords.
Using a computer security lock
A security keylock notch, located on the rear of the computer, lets you connect
a Kensington-compatible computer security lock.
Wrap a computer security lock cable around an immovable object such as a
table or handle of a locked drawer. Insert the lock into the notch and turn the
key to secure the lock. Some keyless models are also available.
Using passwords

passwords creates several different levels of protection for your computer
and data:
•
Supervisor Password prevents unauthorized entry into the BIOS utility.
Once set, you must enter this password to gain access to the BIOS utility.
See
"BIOS utility" on page 59
.
•
User Password secures your computer against unauthorized use. Combine
the use of this password with password checkpoints on boot-up and
resume from Hibernation for maximum security.
