Original MacBook A2485/A2780 Power Button Cable With Button
This is the MacBook A2485/A2780 Power Button Cable W/Button - Original Pulled Quality, supplied as a complete button module with attached flex for a fast and predictable swap. This part restores reliable power on and sleep/wake control on MacBook Pro 16‑inch platforms where the original button or flex has failed, been torn during service, or shows intermittent response.
Each unit is an original pulled component taken from donor devices inspected for clean contacts, strong tactile click, and intact flex traces. You get a drop‑in assembly that seats in the top case’s power button position and mates to the logic board via fine‑pitch fpc, removing guesswork and cutting bench time.
Compatibility And Key Technical Data
This assembly is compatible with MacBook Pro 16‑inch A2485 (2021) and A2780 (2023) variants across storage and cpu configurations. The module includes the power button cap, integrated sensor board, and the dedicated flex cable terminating in an fpc connector designed for the corresponding logic board header.
The button provides system power on, wake, and sleep input as designed by Apple for these models. Touch id pairing remains bound to the original logic board/button pair, so biometric unlock will not function after replacement unless the matched original sensor is retained. The new module will operate as a standard power key. The flex uses a thin, shielded trace layout for low‑noise switching and is routed for the top right function‑row position used on 2021–2023 ‑inch units.
Reliable Choice For Repair Shops
Original pulled quality means the part comes from genuine MacBook assemblies, not aftermarket reproductions, giving you correct fit, correct connector pitch, and consistent actuation force. Every piece is visually graded, continuity tested end‑to‑end, and click‑tested to confirm tactile response before packaging in an esd safe sleeve.
This is an ideal stocking item for shops handling keyboard or top case replacements, liquid damage recoveries, and no‑power cases where the power key is suspect. The assembly helps resolve symptoms such as no response to the power key, random sleep events from a shorted flex, or cosmetic damage to the key cap after impact.
Installation Notes And Handling
You should disconnect the battery before connecting or removing the fpc to prevent line transients. You should open the bottom case, isolate the battery, remove the small bracket securing the button area, and route the flex in its original channel to avoid pinching. You should lock the fpc latch straight down and avoid bending the cable the pads to preserve trace integrity.
No screws or brackets are included unless explicitly stated by your bundle, so you should retain and transfer original hardware. You should perform a pre‑seal test before reassembly by reconnecting the battery and verifying that a single press triggers the boot chime and that the system sleeps and wakes on demand. You should finish by reseating any shields and replacing the bottom case with the correct torque on the pentalobe screws for a clean result.
