Abstract: Systems, apparatuses and methods may provide for technology that detects a low battery condition in a computing system including an integrated graphics processor and a discrete graphics processor, wherein the low battery condition is detected during a pre-boot stage of the computing system. The technology may also disable a root port associated with the discrete graphics processor in response to the low battery condition, conduct an initialization of an integrated display while the root port is disabled, and enable the root port in response to a successful negotiation of increased power by a verified read write code of an embedded controller of the computing system.
