摘要： An exemplary electronic device includes a controller, a first convertor, a second convertor, and a switching unit. The first convertor is configured for receiving a first voltage from an external power supply and converting the first voltage into a second voltage. The controller is coupled to the first convertor for generating a start signal when receiving the second voltage. The second convertor is connected to the controller for receiving the first voltage, converting the first voltage into a third voltage to power an operating unit of the electronic device, and converting the first voltage into a fourth voltage to power the controller when receiving the start signal. The switching unit is coupled to the controller and the first convertor for disabling the first convertor when the controller receives the fourth voltage. A related power supply unit is also provided.

摘要： An audio and video (AV) apparatus includes a player module for playing audio and video files, generating audio and video signals, and an internal display and an internal speaker. The AV apparatus further includes: a first switch for generating first instructions; an output module for being externally connected to output the audio and video signals; and a control module connected to the first switch. The control module being configured for disabling the internal display and internal speaker at receiving the first instructions at a situation that the output module is externally connected to output the audio and video signals, and disabling the internal display while keeping the internal speaker enabled at receiving the first instruction at a situation that the output module is not externally connected. A method for controlling the audio and video apparatus is provided as well.

摘要： A power supply system for an electronic device includes a first and a second connector, a switch, and a controller. The first connector is used for connecting to a first power source. The second connector is used for connecting to a second power source, wherein the second power source is rechargeable. The switch establishes a connection between the first connector and the second connector so as to allow the first power source to charge the second power source. The controller detects a presence of the first power source and the second power source, and controls the switch to periodically establish the connection at the absence of the second power source, and to continuously establish the connection at the presence of the second power source.
