I decided to take out the logic board because I had a water problem. As you can problably guess all the componentes from both sides of the board, near the ventilation, were dirty with some green and white stuff so I cleand it all up with isopropilic alcohol. I assembeled it buck up and it turns on but it doesnt run the osx, screen doesnt turn on, you cant hear the welcome sound every time you turn on a mac and the only thing you can hear is the fan spinning faster and faster until it reaches its top speed and it stays like that. what can I do to fix it??

Three years later, the answer is that you need to reset your SMC.

ROBOLOBO -

is it possible to assemble the laptop completely without the unibody enclosure?

Grant Kendrick - 返信

Yes you can, but it would be unsafe for the macbook

Ryan -

Thanks for this!

Yesterday I embarked upon replacing the keyboard in mine for the 2nd time, and ripped out one of the connectors! After pouring over schematics, the board layout, etc. this guide told me exactly what connector it was; the webcam! This means I won’t be replacing it, since I run Linux the webcam drivers would not work anyway. This saves me a massive headache, microsoldering (Louise Rossman style) and probably breaking more things.
