Abstract: A metered-use computer is operable in a number of states or modes to accommodate manufacture, test, operation and end-of-life. During manufacturing, a security module may be set to a non-metered mode, where no measurements are taken. At the end of the manufacturing process, the security module may be set to an active mode where metering and measurement of the computer are enforced. When terms of a purchase contract or other user agreement are satisfied, the computer may be set to a non-enforcement state where all metering and metering-related security are disabled. A one-time reset of the active mode is supported to allow end-of-line quality assurance testing.
