Abstract:
A computer-implemented method provides power to a fingerprint reader while the remaining components of the information handling system are held in a low power, non-operating state. Placement of a finger across the fingerprint reader is detected with the information handling system in the non-operating state. A fingerprint is read and a corresponding fingerprint image is generated. The fingerprint image is buffered and an embedded controller is triggered to start an authentication device having a secure storage. The fingerprint image is compared to a fingerprint template contained in the secure storage. In response to the fingerprint image matching the fingerprint template, the authentication device signals the embedded controller to activate a user authenticated wake-up cycle to provide power to the other components of the information handling system such that the information handling system activates an operating system and enters a fully powered and user authenticated, operational state.
