MacBook Air 13-inch A3240 IO Board (M4, 2025)

Description

The input/output component in a laptop handles audio and secondary data connections. If the computer shows missing sound from wired headphones, a loose audio jack, or an unresponsive side port, the MacBook Air 13″ A3240 IO Board may be faulty. This internal spare piece supplies a physical hardware solution to swap out the failing component. Once installed, it reconnects the internal circuits and brings normal audio port function back to the device.

Key Benefits:

• Connects wired headphones to the main logic board for clear audio output.
• Controls data transfer speeds for the secondary ports on the side.
• Swaps out a worn or physically broken headphone jack.
• Fits directly into the left side of the computer casing.
• Corrects issues with missing sound when using physical audio plugs.
