1. A monitoring system capable of monitoring a central processor unit utilization in a computer, the system comprising:
a power supply for supplying a core voltage to the central processor unit; and
a comparing circuit for comparing a voltage proportional to the core voltage to a reference voltage and producing a sense voltage, a first input of the comparing circuit connecting to the power supply and a second input of the comparing circuit connecting to a reference voltage source that outputs the reference voltage, wherein the reference voltage is set at a level corresponding to a nominal off-load voltage value for the core voltage.
