An apparatus comprising a battery and a circuit. The battery may be configured to provide a persistent power source. The circuit may comprise a processor, self-test logic, internal storage and logic circuitry. The self-test logic may be configured to perform a status check to determine an operating status of the logic circuitry. The processor may be configured to enable a first portion of the status check to be performed during a shutdown of the apparatus and a second portion of the status check to be performed during a bootup of the apparatus. The battery may provide the persistent power source to the internal storage after the shutdown of the apparatus. Parameters generated during the first portion may be stored in the internal storage. The parameters stored in the internal storage may be used with the second portion to determine the operating status of the logic circuitry.
