An audio wake-up circuit for use to wake up a computer system from a sleep mode. Such an audio wake-up circuit comprises an operational amplifier (Op-Amp) coupled to receive an audio input from a user via an audio input device, and having a feedback network arranged to compare the input audio with an attenuated version of the output audio and make an appropriate amplification; and a switching device coupled to the operational amplifier (Op-Amp) and arranged to assert a power management (PME#) wake event so as to wake up the computer system from a sleep mode, when the input audio from the user exceeds a predetermined level.
