1. A computer-implementable method for detecting whether a power adapter is coupled with an information handling system satisfies certain power requirements of the information handling system, the method comprising:

  • detecting when a power adapter is coupled to the information handling system;

    determining a power adapter power capacity upon detection of coupling of the power adapter to the information handling system;

    determining whether the power adapter power capacity satisfies the power requirements of the information handling system; and

    ,preventing the power adapter from powering the information handling system when the power adapter power capacity does not satisfy the power requirements of the information handling system via an adapter override circuit, the adapter override circuit being included within the information handling system, the adapter override circuit comprising a power detector control circuit and a switch, the switch of the adapter override circuit being located between the power adapter and power distribution of the information handling system, the power distribution comprising a layer of a printed circuit board, the power detector and control circuit activating a power adapter disable signal when the power adapter power capacity is lower than the power requirements of the information handling system, the power adapter disable signal causing the switch to stop powering the information handling system from the power adapter.
