An information handling system touchscreen display detects touches at a touch detection surface as inputs to the information handling system based in part upon periodical calibrations performed by a touch controller. An embedded controller detects placement of a keyboard on the touchscreen display and in response commands the touch controller to cease the periodic calibrations for at least the portion of the touchscreen display on which the keyboard is placed. For instance, the embedded controller interfaces with a Hall sensor disposed under the touchscreen display that detects a magnet integrated in the keyboard. At removal of the keyboard, the embedded controller commands the touch controller to perform a calibration to update touch detection.
