Using other services
If you travel with your computer or relocate it to a country where your desktop or notebook computer

entitles you to obtain warranty service throughout the warranty period. Service will be performed by
authorized Service Providers.
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.
