  • Patent number: 7093248
    Abstract: Alerts are targeted for display at an information handling system by associating conditions with alerts and downloading for display an alert only to information handling systems that meet the conditions of the alert. An alert list that includes alerts and associated conditions in an Extensible Mark-up Language file is periodically queried for retrieval at information handling systems and parsed to determine alerts targeted to the information handling system. Only relevant alerts are downloaded and displayed at each information handling system to minimize user distraction. Specific targeting is provided by logical expressions that may state conditional alert configuration parameters with precision to limit the number of information handling systems targeted for the alert to very specific configurations.

  • Publication number: 20050192817
    Abstract: Information handling system consumable orders, such as orders for printer supplies, are placed through a network, such as the Internet, by automatically monitoring consumable quantity to detect a consumable order trigger event for presentation at the information handling system. User initiated selection of a consumable order communicates order information to a consumable order server, which pre-populates a completed order form for display at the information handling system, such as an order form with consumable information, payment information and delivery information. For instance, the consumable order server is associated with the manufacturer of the information handling system and applies the payment and delivery information from the purchase of the information handling system to complete the order form so that a user need only confirm the accuracy of the completed order form to place the consumable order.

  • Publication number: 20040176964
    Abstract: A method and system are provided which substantially reduce the disadvantages and problems associated with previous methods and systems for resolving issues related to information handling system failures. A self-support application on an information handling system diagnoses failure issues not correctable by self-support and communicates a diagnostic code through a network to a service center. The service center determines the failure issue from the diagnostics code and refers the failure issue to an issue resolution source associated with resolution of the failure issue, such as automated support resolution for failure issues having a known resolution, or phone or electronic message support for failure issues not having a known resolution.

  • Publication number: 20040148223
    Abstract: Direct marketing subsystems associated with information handling systems download coupon lists from a direct marketing server, each coupon of a coupon list having one or more associated conditions and items offered for sale. A coupon relevance module analyzes the coupon list conditions to identify coupons that are relevant to the information handling system for display at the information handling system. Activation of a coupon initiates purchase of the item associated with the coupon by communication with the direct marketing server. A unique identifier of the information handling system associates selection of the coupon with an account for charging and delivery of the purchased item.
