Abstract:
A restart controller for an information handling system includes a first latch and a second latch. An output of the second latch is coupled to an input of the first latch. The restart controller is configured to detect that the information handling system has been shut down responsive to a first disorderly shutdown, and in response to detecting the shut down, to set the first latch, initiate a first startup of the information handling system to enable a remote wake mechanism of a chipset of the information handling system, and determine, at the second latch, that a basic input/output system (BIOS) of the information handling system is operational. In response to determining that the BIOS is operational, The restart controller is further configured to initiate an orderly shutdown of the information handling system, and clear the first latch.
