Abstract
A system and method of modifying power use within an information handling system is disclosed. In one form, a method of managing power within an information handling system is disclosed. The method can include establishing a threshold power level of a first information handling system, and detecting a first power demand of a first operating state in excess of the threshold power level. The method can also include detecting a request to invoke a first forced reduced power state of the first information handling system, and determining a first alternative power state different from the threshold power level and the first forced reduced power state. The method can further include initiating the first alternative power state.
Claims18
A method of managing power within an information handling system, comprising:
- establishing a threshold power level of a first information handling system;
- detecting a first power demand of a first operating state in excess of the threshold power level;
- detecting a request to invoke a first forced reduced power state of the first information handling system;
- initiating the first forced reduced power state;
- receiving, from the first information handling system, a request to initiate a first alternative power state via an out-of-band network signal;
- determining the first alternative power state based on a first profile of the first information handling system, wherein the first profile includes a specific configuration of components to be powered within the first information handling system, wherein the first alternative power state is between the threshold power level and the first forced reduced power state;
- initiating the first alternative power state;
- releasing the first forced reduced power state of the first information handling system;
- detecting a second forced reduced power state of the first information handling system, wherein the second forced reduced power state is greater than the first forced reduced power state and the second forced reduced power state is in response to the first alternative power level exceeding the threshold level;
- and
- outputting a second alternative power level to the first information handling system based on a second alternative power state, wherein the second alternative power level is less than the first alternative power level, wherein the second alternative power level is in response to the detection of the second forced reduced power state and based on a second profile of the first information handling system.

A power management system comprising:
- a management controller operably coupled to a BIOS of a first information handling system, the management controller configured to manage allocation of power sufficient to satisfy a first power demand of the first information handling system, to detect a first forced reduced power state of the first information handling system, to output a first alternative power level to the first information handling system based on a first alternative power state, wherein the first alternative power level is less than a first threshold level, and to initiate releasing the first forced reduced power state of the first information handling system, to detect a second forced reduced power state of the first information handling system, wherein the second forced reduced power state is greater than the first forced reduced power state and the second forced reduced power state is in response to the first alternative power level exceeding the first threshold level, to output a second alternative power level to the first information handling system based on a second alternative power state, wherein the second alternative power level is less than the first alternative power level;
- a monitor accessible to the management controller, the monitor configured to monitor the first power demand;
- and
- a power distribution system coupled to the information handling system, the power distribution system configured to receive a first alternative power output generated in response to the detected first forced reduced power state, and to set the first alternative power state based on the first alternative power output and based on a first profile of the first information handling system, wherein the first profile includes a first specific configuration of components to be powered within the first information handling system, wherein the first alternative power state is set to a power level proximal to the threshold power level, to set the second alternative power state in response to the detection of the second forced reduced power state and based on a second profile of the first information handling system.

An information handling system comprising:
- a processor configured to receive a request to invoke a first forced reduced power state, the processor configured to reduce an operating state to a minimal operating level, to detect the first forced reduced power state of the first information handling system, to output a first alternative power level to the first information handling system based on a first alternative power state, wherein the first alternative power level is less than a first threshold level, and to initiate releasing the first forced reduced power state of the first information handling system, to detect a second forced reduced power state of the first information handling system, wherein the second forced reduced power state is greater than the first forced reduced power state and the second forced reduced power state is in response to the first alternative power level exceeding the first threshold level, to output a second alternative power level to the first information handling system based on a second alternative power state, wherein the second alternative power level is less than the first alternative power level;
- and
- a power distribution system coupled to the processor and responsive to the first forced reduced power state and the first alternative power state, wherein the first alternative power state is generated in response to a request to initiate the first forced reduced power state received via an out-of-band network signal and based on a first profile of the first information handling system, and wherein the first profile includes a specific configuration of components to be powered within the first information handling system, and the power distribution system is further configured to set the second at alternative power state in response to the detection of the second reduced power state and based on a second profile of the first information handling system.
