Abstract
A computer system warranty upgrade method and apparatus are provided. When a warranty upgrade is desired, the computer requesting a warranty upgrade sends its configuration information to a remote warranty server computer. The warranty server prepares a warranty price quote specific to the particular configuration of the requesting computer. When the price quote is paid, the warranty server encrypts and transmits a warranty authorization to the requesting computer. The warranty authorization includes warranty type, duration, the specific configuration warranted and an identification number unique to the requesting computer. These data are authenticated and validated by a secure processor in the requesting computer. After validation, the validated data is stored in secure storage by the secure processor.
