The lid angle sensor for the 2024 MacBook Air 13″ M3 (A3113) plays an important role in how the device responds when the lid is opened or closed. If your MacBook Air is not sleeping, waking, or adjusting the display properly when you move the lid, this part may be the cause. Replacing the faulty sensor restores the correct functionality, helping the system recognize lid movement and respond as intended.
