1. A method of thermal management in a computer system, comprising:
- receiving a power signal from a power source, the power signal indicating an amount of power furnished to a portion of the computer system;
generating a first signal based on the power signal indicating a thermal condition of the computer system portion; and
generating a second signal to effect a power management action based on the first signal.

Abstract
A method to manage power consumption in a computer system includes receiving a power signal from a power source (the power signal furnishing power to a portion of the circuit), generating a first signal indicating the power transferred from the power source to the portion of the computer system, and generating a second signal to effect a power management action based on the first signal. By way of example, the power source may be a switching or linear power supply, and the second signal may be a fan control signal, a processor halt signal, or a processor interrupt signal.

9. A method, comprising:
-
receiving a power signal from a power source, wherein the power signal is a pulse width modulated signal, the pulse width modulated signal indicating an amount of power furnished to a portion of a computer system;
generating a representation of a duty cycle of the pulse width modulated signal; and
generating a second signal to effect a power management action based on a state of the representation. - View Dependent Claims (10, 11, 12, 13)
