Disclosed is a hybrid-system computer comprising a first system, a second system and a power supply unit, wherein the power supply unit is connected to the first system and the second system, respectively, and wherein power consumption in an operating state of the second system is lower than that in an operating state of the first system; the hybrid-system computer further comprises: a triggering unit configured for obtaining a switching command when the first system is in an operating state and the second system is in a non-operating state; and a switching unit connected to the triggering unit, the first system and the second system, respectively, and configured for receiving the switching command and controlling the first system to enter a non-operating state and the second system to enter an operating state based on the switching command. With the hybrid-system computer, in the case that only low power consumption applications are required, the first system is caused to enter a non-operating state, and the second system is put into an operating state. Therefore, the overall power consumption can be effectively reduced.
