Where to start repairing MacBook
I have a Mid-2009 MacBook from a friend who asked me whether I could repair it as it has been damaged by spilling coca cola over it. I have repaired pc's and laptops but never a macbook but I want to give it a try. I have checked several Ifixit repair guides but before I start to try to open the macbook, I would like to know where to start in this situation :
I attached the macbook again to the electrical circuit. The led was orange and changed to green after some hours so it may be that the battery is still working. The machine does however not react when pushing the on/off button.
What would be the steps to detect whether one ore more parts are still intact (battery, motherboard, fan, ...) and which parts should I test first? I have no other macbook or spareparts available. I know a little of testing voltage etc on a circuit or electrical parts in case that is a starting point. As it may be that only the power socket has gone , how could I detect this and can I replace it?
Is this a good question?
