Touchpad Assembly
The capacitive sensor relies on a stable grounding path to the aluminum chassis to filter out electromagnetic interference (EMI). Over time, the conductive contact points or grounding clips lose tension or oxidize, causing the controller to misinterpret floating voltages as touch inputs. Replacing the module provides a fresh capacitive matrix and new grounding interfaces.

Internal Li-ion Battery
Lithium-ion cells located directly beneath the touchpad can undergo outgassing and volumetric expansion due to thermal cycles. This physical swelling exerts vertical pressure on the underside of the touchpad, causing erratic tracking and preventing the mechanical 'click' from registering correctly.
