    Hi There,

    I'm new on this forum.
    I'm totally not an Apple specialist, even a mac user.
    Fixing things that doesn't work anymore seems to be a challenge for me :D

    So, I have a macbook pro A1278 in front of me that won't power on anymore.
    What happened before ...
    There was a glass of wine spilled onto the 6 month old macbook.

    Now the macbook won't power on aymore.
    opened the device, cleaned everything (find no wine inside, only in the keyboard) and fixed back together.

    When I push the powerbutton, still nothing.
    When I plug in the magsafe plug, the macbook power on automatically and boots properly :eek:

    When I disconnect the magsafe, the macbook keeps powered on.
    When I close the cover it goes in sleepmode. Open the cover the power comes back on.

    When I shutdown trough the menu, it won't power on again until i disconnect and reconnect the magsafe. Then the macbook automatically startup again.

    Any sugustions ?
    Is there something to check on the logic board ?

    Sorry for my bad translation.
    Greetins from Belgium :eek:

    This same thing happened with my brother's old Asus laptop. He spilt water on the keyboard and after that it wouldn't boot unless plugged in. I think the motherboard was damaged. Luckily for him he was looking to buy a new laptop soon anyway.

    An Asus is not a :apple: :D

    I disassembled the logic board yesterday. Cleaned it well with isopropyl.
    Disassembled the layers of the keyboard and cleaned them also.

    Today I'm going to put everything back together and try to "hotwire" start the MBP with the powerpads or trough the pins on the keyboard connector.

    Fingers crossed :cool:

    I fixed the problem. The macbook is working again :eek: :cool:

    The problem was a shortcircuit in the power on button from the keyboard.
    I tried to "jumpstart" the macbook by shortening pin 5 & 29 on the keyboard connector.

    With this trick i could start the macbook on a normal way.
    The macbook was also charging normally with the keyboard disconnected.

    So i decided to order a new keyboard and replaced it with the faulty one, and voilla... macbook working again.
    Keyboard --> What a bad design ! Why so many screws ??

    So if you ever spill something onto the keyboard, try above steps to fix the problem.
