Abstract
In the event of a TDM failure, the associated computing device is either discarded or sent back to an original equipment manufacturer's facility for refurbishment. Field replacement of TDMs is typically not possible due to the lack of a secure process to recalibrate the touch controller to function properly with a replacement TDM. The presently disclosed systems and methods enable secure recalibration of a touch controller within a computing device to operate correctly with a new TDM field installed in the computing device. More specifically, the presently disclosed systems and methods provide a mechanism for detecting that a TDM has been field replaced, unlocking calibration data, performing a calibration process, and locking the new calibration data.
