Important notes about Touch ID and safety The Touch ID sensor is uniquely paired to the logic board at the factory. Always move the original Touch ID sensor from your old A3240 board to the new one, or Touch ID features may be disabled. Always disconnect the battery first and discharge residual power before unplugging or reconnecting flex cables. Work on an ESD safe surface and avoid metal tools on logic board components whenever possible. If your A3240 has heavy corrosion, burnt components, or data you cannot lose, consider TEKDEP professional data recovery instead of attempting chip level repair on your own. #MacBookAirM4 #A3240Repair #LogicBoardReplacement #TekDep #AppleRepair #MacBookAir2025
