Motherboard with a smart charging function

A motherboard having a smart charging function and comprising:

• a connection interface configured to an electrical device;
• a switching circuit coupled to the connection interface and comprising a first transmission path and a second transmission path;
• a first controller coupled to the switching circuit and communicating with the electrical device via the first transmission path;
• a second controller coupled to the switching circuit and communicating with the electrical device via the second transmission path;
• a voltage converter circuit coupled to the connection interface, the first controller and the second controller,
• wherein in a standard charge mode, the first transmission path is turned on and the first controller directs the voltage converter circuit to generate first charge power to the electrical device;
• wherein in a fast charge mode, the first controller determines whether the electrical device has a specific operating system,
• wherein responsive to determining that the electrical device does not have the specific operating system, the second transmission path is turned on and the second controller directs the voltage converter circuit to generate second charge power to the electrical device,
• wherein responsive to determining that the electrical device has the specific operating system, the first controller determines whether the electrical device is a specific device,
• wherein responsive to determining that the electrical device is not the specific device, the first controller directs the voltage converter circuit to generate third charge power to the electrical device, and responsive to determining that the electrical device is the specific device, the first controller directs the voltage converter circuit to generate fourth charge power to the electrical device.
