It might be able to turn of the CPU, but everything else would have to keep running. Graphics hardware does not deal well with frequent state changes. Network hardware would still need to run to keep its clock in sync with the signal. So, you get to turn off a handful of components, which is where we already are today - CPUs spend most of their time in deep sleep states. USB devices and chipsets implement sleep states. Graphics hardware clocks down significantly.
