Abstract: Systems, apparatus, articles of manufacture, and methods for external display power loss detection and sleep state recovery are disclosed. Example apparatus disclosed herein include first circuitry to set an output of the first circuitry to a first logic value after a determination that a compute device is to enter a sleep state, and set the output to a second logic value after a determination that the compute device is to exit the sleep state. Disclosed example apparatus also include second circuitry to switch control of a hot plug detect (HPD) input of high-definition multimedia interface (HDMI) circuitry between an output of power loss sensing circuitry and an HPD line of an HDMI port of the HDMI circuitry based on the output of the first circuitry.
