    Macbook keyboard is dead, but recognises SMC reset. Should this be possible?
    My Macbook's keyboard has been dead for quite a few months now and I've been using an external USB keyboard. Although it's a lot of work, i'm planning on taking it apart and replacing it with a new one.

    One thing that has me curious though is that when trying an SMC reset (Shift, Control, Option, Power), it recognises the input on the keyboard because my MagSafe adapter light changes colour like it is supposed to.

    My question is, if my keyboard really is dead, why does my MacBook recognise the SMC reset?

    The power button still works and so does the backlight. I've also tried a PRAM reset with no luck.

    My guess is...if the keyboard is definitely dead...when you do the 4-key combo of (Shift, Control, Option, Power)...your MacBook is only reacting to the pressing of the Power button (powering off)...and not really doing an SMC reset.

    Like you said with the PRAM reset...in the PRAM reset you don't press the power button...thus nothing is happing with a PRAM reset.

    That could very well be it. I thought the MagSafe light only changed colour when all 4 keys are pressed though.

    I have a 17" MacBook Pro with 4 keys not working (or partially working). I bought a used topcase via ebay...so I'm about to do the same project. I've been using an external keyboard most of the time as well.

    I've been putting it off...since as you said...it's a pretty involved project.

    I successfully replaced mine yesterday. I bought a new keyboard and plugged it onto the logic board to test it and it worked. So i just went for it and took it all apart. It's lengthy process but it was well worth it. Good luck with your repair!
