Abstract
A power adapter comprises a power supply to output power for powering a powered device when the powered device is coupled to the power adapter. The power adapter further comprises a disable throttle indicator that, when the powered device is coupled to the power adapter, indicates to the powered device that the powered device need not reduce an amount of power used by the powered device in order to keep the power adapter within regulation.
Claims23
A power adapter comprising:
- a power supply to output power for powering a powered device when the powered device is coupled to the power adapter;
- and
- a disable throttle indicator that, when the powered device is coupled to the power adapter, indicates to the powered device that the powered device need not reduce an amount of power used by the powered device in order to keep the power adapter within regulation.
A power adapter comprising:
- a power supply to output power for powering a powered device when the powered device is coupled to the power supply;
- wherein, when the powered device is coupled to the power adapter, the power supply communicates, to the powered device, information indicating to the powered device that the powered device need not reduce an amount of power used by the powered device in order to keep the power adapter from entering a current limited state.
A powered device comprising:
- an interface to receive power from a power adapter;
- wherein the powered device comprises a power management function that, when performed, controls an amount of power used by the powered device so that a load current drawn by the powered device is below a maximum load current;
- wherein the powered device further comprises a disable throttle interface to receive an indication from the power adapter that the power management function need not be performed.
A powered device comprising:
- means for receiving power from a power adapter;
- means for using at least a portion of the received power to power at least one component;
- and
- means for receiving an indication that the powered device need not reduce an amount of power used by the powered device in order to keep the power adapter within regulation, wherein when the indication is received, the amount of power used by the component is not reduced in order to keep the power adapter within regulation while the powered device receives the power from the power adapter from which the indication was received.
