Many computing device may now include two or more graphics subsystems. The multiple graphics subsystems may have different abilities, and may, for example, consume differing amount of electrical power, with one subsystem consuming more average power than the others. The higher power consuming graphics subsystem may be coupled to the device and used instead of, or in addition to, the lower power consuming graphics subsystem, resulting in higher performance or additional capabilities, but increased overall power consumption. By transitioning from the use of the higher power consuming graphics subsystem to the lower power consuming graphics subsystem, while placing the higher power consuming graphics subsystem in a lower power consumption mode, overall power consumption is reduced.

Many computing device may now include two or more graphics subsystems. The multiple graphics subsystems may have different abilities, and may, for example, consume differing amount of electrical power, with one subsystem consuming more average power than the others. The higher power consuming graphics subsystem may be coupled to the device and used instead of, or in addition to, the lower power consuming graphics subsystem, resulting in higher performance or additional capabilities, but increased overall power consumption. By transitioning from the use of the higher power consuming graphics subsystem to the lower power consuming graphics subsystem, while placing the higher power consuming graphics subsystem in a lower power consumption mode, overall power consumption is reduced. A processor executes application software and driver software. The driver software includes first and second driver components for respectively controlling operation of the first and second graphics subsystems. A further proxy driver component routes calls (e.g. API/DDI calls) to one of said first and second driver components, in dependence on which of the first and second graphics system is in use.

Driver architecture for computing device having multiple graphics subsystems, reduced power consumption modes, software and methods

A method of operating a device is provided. The method includes transitioning the GPU to a substantially disabled state in response to a first received signal, and generating, while the GPU is in the substantially disabled state, a response signal in response to a second received signal. The response signal is substantially similar to a second response signal that would be generated by the GPU in a powered state in response to the second received signal.

Method and apparatus for responding to signals from a disabling device while in a disabled state

A portable electronic apparatus includes first and second modules, and a control unit. The first module includes a first charging circuit to be coupled to a first power source, and a first battery unit coupled to the first charging circuit. The second module is connected removably to the first module, and includes a second charging circuit to be coupled to a second power source, and a second battery unit coupled to the second charging circuit. The control unit enables the first and second battery units to be charged independently and respectively through the first and second charging circuits using the first and second power sources when the second module is disconnected from the first module, and enables the first and second battery units to be charged through the first charging circuit using the first power source when the second module is connected to the first module.

Portable electronic apparatus including detachable system and expansion modules

A power supply system for supplying power to a load of an electronic apparatus includes first and second battery units, and a selector coupled to the load and the first and second battery units. The selector is operable so as to break electrical connection between the second battery unit and the load and to simultaneously make electrical connection between the first battery unit and the load when a remaining capacity of the first battery unit is higher than a predetermined reference value, and so as to break electrical connection between the first battery unit and the load and to simultaneously make electrical connection between the second battery unit and the load when the remaining capacity of the first battery unit is lower than the predetermined reference value. A controller coupled to the selector, is responsive to a first control command, which may be issued by the electronic apparatus, so that the controller overrides the detector and enables operation of the selector in the first state.
