Methods and apparatus to operate closed-lid portable computers are disclosed. An example portable computer includes a first display on a lid of the portable computer, the first display to be deactivated when the lid is in a closed position; a second display distinct from the first display, the second display to be visible when the lid is in the closed position; instructions; and processor circuitry to execute the instructions to cause activation of the first display in response to a user interaction with the second display while the lid is in the closed position.

Methods and apparatus relating to platform power consumption reduction via power state switching are described. In one embodiment, control logic causes a processor to enter a first low power consumption state (e.g., S0ix) instead of a second low power consumption state (e.g., S3) based on whether a threshold time period exists between a first wake event (e.g., corresponding to a first one of one or more awake requests) and a second wake event (e.g., corresponding to a second one of the one or more awake requests). Other embodiments are also claimed and disclosed.

The first graphics processing subsystem includes a first application processor, a first graphics processing unit, and a first memory. The second graphics processing subsystem includes a second application processor, a second graphics processing unit, and a second memory. The first graphics processing unit renders a first GUI. The screen displays the first GUI. The second graphics processing unit renders a second GUI, and the second GUI and the first GUI belong to different interface types. The screen displays the second GUI. A display processing method applied to the electronic device is also provided, wherein the first graphics processing subsystem can be switched to the second graphics processing subsystem based on complexity of a to-be-displayed GUI.

A control method of a power supply path includes detecting a plug-in state of a first connector through a configuration channel pin of the first connector; acquiring a plurality of rated voltages of a first power adaptor externally connected to the first connector and a rated current corresponding to each of the rated voltages; detecting a plug-in state of a second connector through a direct-current (DC) input pin of the second connector; acquiring a power quota of a second power adaptor externally connected to the second connector; selecting, from the plurality of rated voltages, the largest one that is not greater than an operating voltage, as a selected rated voltage; calculating a power quota of the selected rated voltage; and controlling a switching circuit to couple a power circuit to a power pin of one of the first and second connectors according to the two power quotas.
