Good Afternoon,   To cut it short I have read many forums and communities for this issue but to no remedy.  I have a macbook pro 13" unibody mid 2010.  It types in caps lock.  (stuck).  Cant login in...(caps...password).   I have ordered and replaced the keyboard.  After keyboard replacement it still types in caps.  External USB keyboard works fine.  What do I do now...???  Thanks ahead of time for your response.  p.s.  function key not enabled...shift,well  its a new keyboard.


MacBook Pro, Mac OS X (10.6.4)

    Have you had an Apple technician, such as at an Apple store genius bar, check the MBP?  Did you do the keyboard replacement yourself or did Apple do that?

     

    I would have an Apple tech check it out and see what they say, but sounds like something other than the keyboard is not functioning right...logic board is not reading the key input right.

    This idea may be a bit engrossing, but I imagine that by now you're probably desperate for anything.

     

    If you have an empty or emptiable external drive of at least 20GB, could try installing your OS onto it. Then boot from the external drive and see if the problem persists. If yes, then it is a hardware problem, yet unsolved even with the keyboard replacement. If no, then your system is corrupt and causing the phantom keypress.

    Thank you for your responses.  I fully understand when a request is made for an apple tech to get invovled.  I may do so, although....  I am sorta of a logic board ninja,  If I was to have another job other than the one I have now it would be a repair technician for these devices...  I did replace the keyboard myself.  I respect your answers fully,  I may see a tech for more information or ideas....general consensus if you will.  Now that I think about it... I am in Yuma, Arizona and there is no apples stores here.  I may have to call.  I was hoping for an SMC reset or dvd os repair.  Something software related.  I will keep researching.  In the mean time I am going to dissassemble and check the traces of the logic board with my o scope and component integrity.  Thank you for your responses.

    Mike, sounds like some confusion between the keyboard and logic board...unless there is a reason for two keyboards to have a faulty caps lock key.  Prime candidate would be the cable or connector to the board, the two primary points for confusion.  And since you used two keyboards, assuming different cables, I would start with the logic board connector.

     

    Just some thoughts.

    I recieved a defective keyboard as the space bar did not work.  So I took it apart again, I cleaned the logic board carefully with alcohol and a tooth brush.  Installed a new keyboard a second time and everything works.  Thank you for your responses.  Awarded everyine all the points I could give.

    Wow, two bad keyboards, but sounds great that you have it up and working again.
