Original Pulled Power Button Cable For MacBook A2442/A2779/A2918/A2992
Get dependable power control back with the MacBook A2442/A2779/A2918/A2992 Power Button Cable w/button - Original Pulled Quality. Original pulled assemblies deliver OEM fitment, crisp tactility, and precise alignment in the top‑right power key position.
The assembly includes the flex cable and integrated power button cap/switch, ready to drop into the top case cutout and connect the logic board FPC. The footprint and thickness match factory parts, so reassembly remains flush and stable under the keyboard deck.
Compatibility And Key Technical Data
Compatible models include MacBook A2442, MacBook A2779, MacBook A2918, and MacBook A2992. Functionality covers system power on, sleep/wake, and long‑press shutdown through the integrated tactile switch.
Part type is a power button flex cable with button. Condition is original pulled quality, inspected and function tested. Contents include the flex and button only, without top case, keyboard, or logic board. Connector type is board‑side FPC with latch. Location is the top‑right keyboard row position. Touch ID pairing is logic‑board bound, so fingerprint authentication will not transfer when the button assembly is replaced; power and sleep/wake functions operate normally.
Repair Scenarios And Installation Notes
Use this part when the power key does not click, the flex is torn after a top case swap, liquid ingress has corrod the switch area, or the system does not respond to press or long‑press. Replace it as preventive maintenance whenever the flex shows kinks, crease marks, or compromised adhesive near the button frame.
Disconnect the battery before handling the FPC to avoid transient damage. Open the bottom case, isolate the battery, release the FPC latch, and route the new flex along the factory channels to prevent pinch points. Retain or replace any foam pads and gaskets to preserve key feel and dampen vibration. Use ESD protection and avoid over‑bending the at the button hinge and connector ends.
Testing Checklist And Quality Assurance
Verify a clean tactile click with even travel before full reassembly. Confirm momentary press to wake, standard press to boot, and a 10‑second press for forced shutdown. Check that sleep and wake events register consistently and that the key sits level with adjacent keys.
Inspect the connector latch for full engagement and ensure the flex is not under tension when the top case is secured. Perform a final run test after thermal cycling to room temperature to confirm stable operation and repeatable actuation.
