Abstract: A scheme for restoring a password-protected endpoint device (e.g., a memory device) of a computer system to an operational state from a low power state without requiring user input of a device password. A password received for unlocking the device during a boot process is stored in a secure memory. The password-protected endpoint device subsequently enters the low power state, causing it to lock. During a transition from the low power state to an operational state, it is detected that the password for the endpoint device is stored in the secure memory. The password is fetched from the secure memory and used to unlock the endpoint device, thereby restoring the endpoint device to an operational state.
