    Hi!
    Has anybody encountering some typing problem with the mac? in my case, i would type and the letters would move, as if the space key, back space, the cursor being placed elsewhere, etc are being pressed.

    thus, causing erratic typing.
    its very inconvenient. if not irritating.

    i've check my keyboard keys, and they are all functioning and responsive.
    i figured, this could be a software problem. your thoughts?

    help

    What Mac are you using and what is the OS X version?
    Any external hard drives you connected?

    in older laptops in general... this generally meant that the "keyboard ribbon" is either torn or broken...

    If you've used your macbook for more than a year this may still be a possibility...

    After you've done the normal "rebooting" processes and as suggested (external hard drive issue) it may just be a hardware failure...hope you've still got warranty on your unit if ever...try and bring it to an apple service center

    This happened to me with my old iBook. A keyboard replacement fixed everything.

    there seems to be a very slight bulge in the battery.
    and yes, the notebook is 1 year 8 months already.

    i have apple care. but will the battery be covered by it?
    its xmas, i hope the apple center are not full so i can i have it checked.

    Before anything else try to unmount and remove your external hard drive and see if the problem still there or gone.

    ive unmounted the battery... and everything seems to be working so far.
    as per the external drive, its not the cause..

    now, a trip to the apple center after xmas.. hopefully by new year, macbook is back with me.

    macbook scars to date.
    1. replace hard drive
    2. now this, battery bloating issue

    called apple and was advised that the battery is not covered anymore since cycle count is at 477++
    classified under diminished capacity. anyways, will still try to have it checked with apple service center. it's on thing that a battery has a high cycle count already, but another when the battery bulging is causing a hardware malfunction.

    haay.. your thoughts?



    however, the AppleCare Protection Plan for notebook computers does not cover batteries that have failed or are exhibiting diminished capacity except when the failure or diminished capacity is the result of a manufacturing defect
