First Claim
Patent Images
1. An apparatus comprising:
- logic, implemented at least partly in fixed-functionality hardware, to,determine a power consumption level of a platform based on at least in part power to be supplied by an input power supply;
determine a power limit of an integrated circuit in the platform based on at least in part the power consumption level of the platform;
apply the power limit to the integrated circuit; and
drive the integrated circuit into a low performance state if the power limit of the integrated circuit is less than a thermal design power level associated with the integrated circuit.

Abstract
Systems and methods of managing platform power consumption may involve determining a power consumption level of a platform based on at least in part a current supplied by an AC adaptor. A power limit of an integrated circuit in the platform can be determined based on at least in part the power consumption level of the platform, wherein the power level may be applied to the integrated circuit.
