Description
This Power Button with Touch ID and integrated fingerprint sensor is designed for the 2025 MacBook Air 13″ M4 (A3240). It controls system power functions while enabling secure biometric login and authentication. Replace this component if the power button is unresponsive or the sensor is physically damaged. Installing this part restores proper power operation.
Disclaimer: Touch ID functionality will not work, as the original fingerprint sensor must remain paired with its original logic board for biometric features to function.
