    Dear all,

    I found myself with a problem that few mac owners have.
    The caps lock and num lock on the macbook have to be always on to get the proper behaviour of the keyboard.
    At booting time, caps & num are switching on automatically.
    I found the problem reported by googling a bit, but no solution.
    Do you know if it's a harware or software problem?
    Any solution?
    In that case, is this sufficient to call apple. I just saw it would cost a fortune to call support (3 months just expired)

    Thank you.

    I seem to remember this being a hardware issue, but there's a quick way to test:

    Boot up from the disc that came with the Mac and in the setup program test it. If it's still inverted, it's obviously not software, so you might as well call Apple. If it works fine there, maybe something in the OS got goofed up, so you might try an archive and install.

    I'm assuming you've tried the obvious resets of PRAM and power manager, and applied any firmware updates?

    If you are using a non-Apple keyboard, try pressing: Ctrl+Alt+Shift+Enter simultaneously then release, and see if that resets it. I just had to have an employee at work do that to reset theirs.

    Nope I did not try the PRAM NVRAM PMU reset.
    I just did a PRAM reset and it solved the problem:
    1. Shut down
    2. Command + Option + P + R until reboot

    Thanks for the replies. I hope this will help those I found to have the same problem on forums.

    numlock inverted

    I have a question. This happens only when you have the adaptor pluged in the macbook.

    Becuase it also happened to me, but I turn it off and deplug the magsafe, and i start the macbook again, and all returns to normal.

    Could some one explain me what is the problem ?

    Sorry to bring this back up, but this has started to happen to me too. I have a newish white macbook and, very often, the num & caps locks are inverted. Rather annoying. What do I have to do to permanently fix this?

    numlock inverted

    Same here with a brand new MBP. I had num lock and caps lock on and inverted at each reboot. I have re-installed, now I "only" have the num lock on and inverted.

    I called Apple to be told it is an unknown issue, and therefore there is no solution.
