Abstract:
The portable computer includes a PCIe controller, a DisplayPort connector, and a combination switch. The DisplayPort connector includes a hot plug pin. The combination switch is connected between the PCIe controller and the DisplayPort connector. The combination switch includes a selecting pin electronically connected to the hot plug pin. When the DisplayPort connector is electronically coupled to a discrete graphics card using PCIe, the hot plug pin sends a hot plug voltage signal to the selecting pin, and the combination switch electronically connects the DisplayPort connector to the PCIe controller after receiving the signal.
