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.
Claims18
A portable computer, comprising:
- a PCIe controller configured for attaching a PCIe device to the portable computer;
- a DisplayPort connector comprising a hot plug pin;
- and
- a combination switch connecting the PCIe controller to the DisplayPort connector, and comprising a selecting pin electronically connected to the hot plug pin, wherein when the DisplayPort connector is electronically coupled to a discrete graphics card, the hot plug pin outputs a first hot plug voltage signal, the selecting pin receives the first hot plug voltage signal, and controls the combination switch to electronically connect the DisplayPort connector to the PCIe controller.
A portable computer, comprising:
- a PCIe controller;
- a graphics controller;
- a DisplayPort connector comprising a hot plug pin, the hot plug pin being configured to output a first hot plug voltage signal if the DisplayPort connector is electronically connected to a discrete graphics card, and to output a second hot plug voltage signal if the DisplayPort connector is electronically connected to an external display;
- and
- a combination switch comprising a selecting pin electronically connected to the hot plug pin, the combination switch being configured to electrically connect the DisplayPort connector to the PCIe controller if the selecting pin receives the first hot plug voltage signal from the hot plug pin, and to electrically connect the DisplayPort connector to the graphics controller if the selecting pin receives the second hot plug voltage signal from the hot plug pin.
