An apparatus, system, and method are disclosed for securely authorizing changes to a transaction restriction. A security module securely stores encryption keys for a payment instrument. The payment instrument electronically transacts payments and includes a transaction restriction. An authentication module receives an authentication from a user of the payment instrument. The security module validates the authentication with a first encryption key. In addition, the security module authorizes a change to the transaction restriction using a second encryption key if the authentication is valid. The security module resides on a computer that the user designates as authorized to validate the authentication.

A system, method, and program product is provided that manages a rental computer system by verifying installation of a secure time-day module in a computer system. The computer system is rendered inoperable if the secure time-day module is not installed. A current time-day value is retrieved from the secure time-day module and an end time-day value is retrieved from a secure storage area. The current time-day value is compared to the end time-day value in order to determine whether a rental period has expired. If the rental period has expired, then the user is prevented from using the rental computer system.

In the context of a notebook computer, multiple battery safety measures in the computer, battery pack, and individual battery cells. These battery packs include industry standard safety mechanisms as well as additional safeguards designed to increase safety. The additional safeguards can be categorized in the following ways. The first safeguard deals with multiple, independent levels of battery monitoring. The second safeguard employs abnormal condition detection methods. The third safeguard deals with improvements to mechanical and thermal design.

Hacking a rental computer to use it beyond purchased rental time is prevented by plugging a time card with internal counter into a DIMM socket of the motherboard and encrypting the register locations of the time card with the private key of the motherboard to bind the time card to the motherboard. Thus, if the time card is not detected at boot or if it is removed during operation the computer is disabled. The counter counts down the rented time period as it receives clocking signals, and at the elapse of the purchased period disables the computer.

Serial presence data in the EEPROM of a DIMM is encrypted with the private key of the motherboard with which the DIMM is intended to be used, so that only BIOS of the intended motherboard can decrypt the SPD to complete booting.

Hypervisors are a new technology in the industry that enable multiple Operating Systems to co-exist on a single client. The use of a hypervisor provides a novel approach to determining the operability of an Operating System. Each Operating System is a virtualized Operating System, with its own IP address. According to a preferred embodiment, the capability Operating System has an application that is a monitor program that runs and provides information that is sent to the maintenance Operating System. The monitor program sends a status packet at regular intervals, which contains system power state and is a confirmation that the system is not hung. If the maintenance Operating System does not receive a packet at a regular interval, or in response to a query, then the maintenance Operating System will be aware that the capability Operating System is hung and will take appropriate measures.

An apparatus, system, and method are disclosed for buffering write data. A motion sensor module senses the motion of a motion-sensitive storage device. A direction module writes data to a buffer if the motion exceeds a threshold motion. The direction module further writes the data to the motion-sensitive storage device if the motion does not exceed the threshold motion. In one embodiment, a write module writes the data from the buffer to the motion-sensitive storage device when the motion does not exceed the threshold motion.

A technique is disclosed for storing an electronic record of the existence of licenses available for use in a network of computers and the deployment status of programs covered by the licenses. License tokens are stored on a license server, and the stored license tokens are used to validate the deployment of applications stored on clients associated with the license server. The license server maintains the license tokens for all licensed applications used by the associated clients and maintains a license file for each client. Periodically, the license file containing token data is sent to the pre-boot environment of each client in the system, e.g., by a synching process. A license-maintenance application residing in the pre-boot environment of each client validates the applications stored on the client by comparing them with the token data in the license file upon the occurrence of a pre-boot process.
