Abstract

A method for protecting a password of a computer having a non-volatile memory is disclosed. A password is stored in a non-volatile memory of a computer. The computer is then transitioned to a power saving state. In response to a detection of an unauthorized access to the non-volatile memory during the power saving state transition, a password input is requested from a user. The computer returns to a power-on state from the power saving state when there is a success in authentication of the input password.
