Using other services
If you travel with your computer or relocate it to a country where your desktop or
notebook computer machine type is sold, your computer might be eligible for
International Warranty Service, which automatically entitles you to obtain warranty
service throughout the warranty period. Service will be performed by service
providers authorized to perform warranty service.
Service methods and procedures vary by country, and some services might not be
available in all countries. International Warranty Service is delivered through the
method of service (such as depot, carry-in, or on-site service) that is provided in
the servicing country. Service centers in certain countries might not be able to
service all models of a particular machine type. In some countries, fees and
restrictions might apply at the time of service.
To determine whether your computer is eligible for International Warranty Service
and to view a list of the countries where service is available, go to
http://www.lenovo.com/support/, click Warranty, and follow the instructions on
the screen.

Packs for your preinstalled Microsoft Windows product, refer to the Microsoft
Product Support Services Web site at http://support.microsoft.com/directory/, or

as support for hardware, operating systems, and application programs; network
setup and configuration; upgraded or extended hardware repair services; and
