    Abstract: An apparatus for managing HDMI power is described herein. The method for managing HDMI power can include connecting a high definition multimedia interface (HDMI) of a computing device to a panel, where the computing device is inactive. The method can also include detecting, with the panel, a connection state and an energy request of the computing device through the HDMI. The method can provide power through the HDMI from a power supply of the panel to the computing device based on the connection state and the energy request of the computing device. The method can activate the computing device.
