I have an older Macbook Pro, the A1229, and I just recently replaced the backlit keyboard. Everything went well, except I cannot use the keyboard or trackpad upon startup until I use an external USB or Bluetooth mouse to "wake" (I suppose is a good word to describe) them up. Once I get the cursor moving with the external mouse, the trackpad works fine. Then I open a browser and click somewhere to type in order to activate the keyboard. I have done a few searches and tried to reset the "pram?" I think it's called... What can I do? Thanks!
