    My internal display, keyboard and trackpad are not working. I tried reseting SMC and PRAM - it's not helping.

    When powering up without plugged external display - internal display flashes gray color (so I can assume backlight and led are okay) - then proceeds to starting with black screen. Keyboard is working, I can turn on caps lock, but can't do anything - since black screen. Attaching external display doesn't recognize him.

    However when I power up with external display connected from the begining - it boots up correctly (with only external display usable), i can type my password on external keyboard, but now internal keyboard and trackpad are not working.

    Macbook early 2011 17", I don't know if it matters, but I should replaced battery months ago, it lives for only about an hour now.

    Any hints what I can do? :(

    Open it up and look for a swelling battery I would suggest that some of your connectors on the logic board have been broken by a swelling battery!!

    It's probably not cost effective to fix anymore at that age you could well be looking at a new laptop.

    A 17" is worth salvaging, perhaps. If it is the logic board, a skilled circuit board repair technician may be able to repair it fairly cheaply. Could be cables too.

    To be honest, I bought a retina 15" 2 years ago.. And year ago switched back to 17". I just prefer it. Size, amounts of ports, 2 hard drives..
    However I just replaced keyboard (spilled water) on retina, so I have working computer. Still would like to rescue 17" - like that extra screen space. :)

    Battery is old, but would it be swelling jut because of age?
    I'll check later battery when I get back home.

    I don't think battery is swallen. Also in 2011 17" macbook battery is nowhere near connectors, so I don't think it could be it.

    Yes batteries swell due to age, if it shows no sign of swelling all good it's just what immediately sprung to mind. It doesn't have to be near the connectors if it warps the logic board.

    I removed bottom cover of to check battery, don't see the swelling, however while I had it removed - hour or two later, display in macbook started working again.
    So I'll go with this lead :) Now this macbook is turned off, I'll buy new battery in next days and see then.

    thanks guys! :)
