    Check if your battery is swelling and pushing up on the keyboard.


    You probably have a Macbook with a removable battery (OS 10.4), so try removing the battery and running it on the power adapter. If the space bar etc. work with the battery removed, it's a sure sign a swelling battery is the cause.

    I can understand a swelling battery having an effect on the sace bar but not the back space key. Try resetting the SMC. And PRAM
