A device can include a processor; memory operatively coupled to the processor; a display housing that includes a display operatively coupled to the processor; a keyboard housing that includes a keyboard; a hinge assembly that operatively couples the display housing and the keyboard housing for transitions between an closed orientation, an open orientation and a folded orientation; and wireless communication circuitry that, in a wireless keyboard mode of the folded orientation, operatively couples to the keyboard.

A data report rate adjustment method for use between a computer host and a peripheral device is provided. According to the actual workload level of the computer host and/or the amount of the input data of the peripheral device, the priority or the report rate of the data to be transmitted from the peripheral device can be dynamically adjusted or set. More especially, the unnecessary data report can be avoided. Consequently, the workload of the computer host can be effectively reduced, and the power consumption of the peripheral device can be saved.

Methods and apparatus for scheduling and controlling power management activities are disclosed. An example method includes detecting, by a computing device, playback of video content at a frame rate that is greater than a predetermined threshold frame rate. The example method further includes, in response to the detection of the playback of video content at the frame rate greater than the threshold frame rate, overriding a screen dimming operation of the computing device.

It is provided it is provided a keypad comprising: a voltage bus configured to distribute power in the keypad; and a plurality of keys: a plurality of row key connections; and a plurality of column key connections: A wake-up signal causes a microcontroller to transition from a low-power state to an active state such that the microcontroller can detect which one of the plurality of keys was actuated. Each key is connected to a single row key connection and a single column key connection. Each row key connection and/or each column key connection is provided with a respective port circuit that is configured to connect the key connection with keys of the keypad when the wake-up signal is activated. Each port circuit comprises a respective port switch that is turned off in the low-power state to disconnect the column key connections/row key connections from the keys of the keypad.

A method is disclosed. In one embodiment, the method may include determining a state of an electronic device. In one embodiment, the method may include determining whether the determined state of the electronic device corresponds to a key input working state. In one embodiment, the method may include, in response to the determined state of the electronic device corresponding to the key input working state, operating an input acquisition unit of the electronic device in a key input working mode and displaying a key section on an input section of the electronic device.

According to one embodiment, an electronic device includes a keyboard, a backlight and a hardware processor. The backlight illuminates the keyboard. The hardware processor is electrically coupled to the backlight. The hardware processor is configured to gradually decrease brightness of the backlight during a period of time of which the backlight is continuously on.

A wireless keyboard, comprising a body, several keys, a first detection unit, a second detection unit and a control unit. The several keys are disposed on the body. The first detection unit is disposed on one side of the body. The second detection unit is disposed on the other side of the body corresponding to the first detection unit. The first detection unit and the second detection unit jointly detect a feedback signal therebetween. When the feedback signal corresponds to an activation signal, the control unit activates the wireless keyboard. In some implementations, the wireless keyboard can save power, and does not require users to switch on/off the power supply manually, thereby achieving the purpose of facilitating life.

The disclosure provides a motherboard including a first communication interface and a switch module. The first communication interface obtains a power signal from a second communication interface of a display, the switch module obtains the power signal, and the switch module controls a first power supply to power supply for the USB communication module. The disclosure also provides a computer control system including the motherboard. The motherboard and the computer control system control the computer to save energy via a display.
