    The keyboard and trackpad on my 2023 M3 MacBook Professional (A2992) have stopped working. This laptop computer was working flawlessly, by no means had liquid spilled on it, and it spent 10 days tucked away in a dry drawer. After these 10 days, the keyboard and trackpad not work.

    The facility button nonetheless works – I can flip the machine on or off, and press the facility button a number of occasions to open the Accessibility menu on the lock display screen, however haven’t any manner of interacting with it.

    The keyboard backlight nonetheless works. The trackpad doesn’t do haptic suggestions when “clicked”, it is utterly useless.

    I’ve tried plugging in a USB keyboard utilizing a USB-A to USB-C adapter, which I can use to enter Restoration and Diagnostics modes. I’ve tried re-installing macOS Sonoma from Restoration to no avail.

    Apple Diagnostics returns these error codes:

    • Trackpad NDR006
    • Keyboard NDK001

    I can’t use the exterior keyboard from the login display screen – I get the immediate “Unlock to make use of equipment”, so I am caught and the laptop computer is successfully a paperweight.

    I wish to perceive:

    • What may probably have failed?
    • Is it one thing that might be fastened by cleansing corrosion or re-seating a cable?
    • Is there any manner I can proceed to make use of this machine with an exterior keyboard and mouse?
