Abstract
Systems, apparatuses and methods may provide for technology that configures a computing system to be a power sink from an external display, detects an alternating current (AC) power failure with respect to the external display, and configures the computing system to be a power source for the external display in response to the AC power failure. In one example, the technology places the external display in a low power state after the AC power failure is detected.
Claims24
A computing system comprising:
- a port;
- a charger coupled to the port;
- a processing unit coupled to the charger;
- and
- a memory coupled to the processing unit, the memory including a set of instructions, which when executed by the processing unit, cause the processing unit to:
- configure the computing system to be a power sink from an external display that is coupled to the port,
- detect an alternating current (AC) power failure with respect to the external display, and
- configure the computing system to be a power source for the external display, as it remains coupled to the port, in response to the AC power failure.
At least one non-transitory computer readable storage medium comprising a set of instructions, which when executed by a computing system, cause the computing system to:
- configure the computing system to be a power sink from an external display that is electrically coupled to the computing system;
- detect an alternating current (AC) power failure with respect to the external display;
- and
- configure the computing system to be a power source for the external display as it remains coupled to the computing system in response to the AC power failure.
A semiconductor apparatus comprising:
- one or more substrates;
- and
- logic coupled to the one or more substrates, wherein the logic is implemented at least partly in one or more of configurable or fixed-functionality hardware, the logic to:
- configure a computing system to be a power sink from an external display that is electrically coupled to the computing system through an external port;
- detect an alternating current (AC) power failure with respect to the external display;
- and
- configure the computing system to be a power source for the external display as it remains coupled to the computing system in response to the AC power failure.
