Before traveling internationally with the computer:
Check local customs regulations for restrictions and
requirements on traveling with your computer.
Purchase (from a Compaq authorized dealer, reseller, or
service provider) a power cord for the country where you will
be using the computer. These power cords are designed to
meet the voltage and frequency requirements of each country.
Follow these steps when shipping the computer:
1. Back up your data. Do not expose your backups to electrical or
magnetic impulses while stored or in transit.
2. If there is a diskette or compact disc in a drive, remove it.
3. Turn off the computer and external devices.
4. Close the computer.
5. Disconnect external equipment from the computer.
6. Close the connector cover and all exterior doors.
7. Pack the computer and external devices in their original
packing boxes, or in similar packaging with sufficient packing
material to protect them and prevent shifting or movement in
transit.
