No response from keys on the keyboard

  1. Remove any connected peripherals and eject any ExpressCard.
  2. If only numbers show up, check if NUM lock (F6) is engaged. Note: This step does not apply to MacBook Pro (15-inch Early 2008).
  3. Go to Apple System Profiler and look under the USB Bus tab in the USB device section. If you see Apple internal keyboard / trackpad, go to step 6.
  4. Attach an external USB keyboard. If the external keyboard doesn't work, go to step 6.
  5. Turn off the computer. Check the keyboard flex cable connection to the trackpad and the trackpad flex cable connection to the main logic board (also check connectors for damage).
  6. Start up from the MacBook Pro Mac OS X Install 1 DVD that came with the computer (hold down the "C" key during restart, if possible) to verify that it is not a software problem.
  7. Replace the keyboard.
  8. Replace the top case.
  9. Replace the logic board.
