Abstract

A computer system warranty upgrade method and apparatus are provided. The computer system is programmed to detect a change in its configuration such as when new components are installed. When such a configuration change is detected, the computer system sends a warranty upgrade request including 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 quoted price is paid, the warranty server digitally signs 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 verified data is stored in secure storage by the secure processor.

Claims

1. A method of upgrading the warranty of a computer system including a plurality of components in a configuration, the method comprising:

receiving from a requestor a request to upgrade an existing warranty to cover a new configuration of the computer system;

detecting, by the computer system, a configuration of the computer system;

determining if the configuration of the computer system is different than an original configuration of the computer system;

asking, by the computer system, a computer user if a warranty upgrade is desired prior to sending;

sending, by the computer system, a warranty upgrade request to a remote warranty processor, the warranty upgrade request including configuration information for field replaceable units (FRUs) in the configuration;

determining a price to upgrade the warranty, using factors related to the configuration of the computer system, wherein one or more of the said factors are selected from the group consisting of;

field replaceable units in the configuration, warranty time remaining, reliability of components in the configuration, age of components in the configuration and replacement cost of components in the configuration;

communicating the price to upgrade the warranty to the requestor; and

sending a warranty authorization to the computer system after acceptance of price to upgrade the warranty, wherein the warranty authorization includes a unique identification number of the computer system.

2. The method of claim 1 further comprising:

receiving, by the computer system, the price to upgrade the warranty.

3. The method of claim 1 further comprising:

receiving, by the computer system, a warranty authorization including a warranted configuration describing the configuration to be warranted.

4. The method of claim 1 further comprising:

receiving, by the computer system, a digitally signed warranty authorizing including a warranted configuration describing the configuration to be warranted.

5. The method of claim 1 wherein the warranty authorization includes warranty type information.

6. The method of claim 1 wherein the warranty authorization includes warranty duration information.

7. The method of claim 1 further comprising:

authenticating, by the computer system, a digitally signed warranty authorization.

8. The method of claim 1 further comprising:

comparing, by the computer system, a warranted configuration in a warranty authorization with the configuration of the computer system, and storing the warranty authorization in secure storage if the warranted configuration matches the configuration of the computer system.

9. The method of claim 1 wherein a secure processor in the computer system performs the comparing and storing.
