Could a failing Steam Deck Touchpad cause the VALVE STEAM DECK LCD to have symptom: Not Vibrating?

The trackpad's vibration is generated by a Linear Resonant Actuator (LRA) integrated into the touchpad module. If haptics are missing but touch input remains functional, the failure is localized to the LRA coil or the haptic driver circuit on the touchpad's daughterboard. Replacing the entire touchpad assembly ensures a new electromechanical link is established, bypassing potential Flex Flat Cable (FFC) degradation or actuator fatigue.

// ENGINEER'S LOG

The failure involves the disruption of the haptic feedback loop. In the Steam Deck, haptics are not merely 'rumble' but are used to simulate the physical displacement of the trackpad. This is achieved via a voice coil and magnet assembly (LRA). A 'Not Vibrating' state suggests the LRA is not receiving the required Pulse Width Modulation (PWM) signal from the controller board, or the actuator's internal spring has shifted out of its narrow resonant frequency band. There is a high statistical correlation between this symptom and a software-induced state where the haptic intensity is set to zero in the configuration files, though a persistent lack of vibration after a factory reset indicates hardware continuity failure.
