MacBook 2006 did not want to sleep when closing the lid
The laptop always had to be forced into a deepsleep because it never went into sleep and was draining the battery. The sleep button on the apple menu did not work either for some magic reasons.
The part matches exactly. Most of the time is spent talking the body apart until the keyboard can be removed.
The two plastic inserts in the connector in which the metal threads for the screws reside can not take much torque. Carefully tighten these or you may have to superglue the plastic back into the connector. All apple screws seem to have thread locker to prevent loosening. Anyway I notice that every screw I touched on that MacBook was loose. If you do not have thread lock you can use nail polish instead. After the repair I was not sure if this fixed the problem: It did. The clue is to actually be patient. It takes 10-20 sec before the white light in the front start pulsing indicating sleep mode. I was not aware of this after a long period of not working at all.
