Keyboard and Trackpad stopped working
The keyboard and trackpad on my MacBook (Early 2009) stopped working. They work fine if I press the option key while booting or do anything else before booting such as reset NVRAM but once the OS boots up completely they don't work.
I also tried using external keyboard and mouse but the issue persists.
Is this a good question?
You say you have also tried using an external keyboard & mouse. Is that to say they work without any issues? It's only the built-in keyboard & trackpad that has problems - Is that correct? And both external units are USB wired Vs Bluetooth correct?
