Hello, I have a trouble with a MacBook white, late 2008. I have replaced the inverter and its cable, because the display remained all black (but with a light I noticed that the MacBook was working). Despite I had followed the guide with great attention, the MacBook never turns on. The LED of Magsafe is green (the battery was already drained), but when I try to power on the MacBook, there isn’t any sign of life: no sound, no fan… nothing. What can I try to fix it? I read that upper case cable can cut out even the power button: I remove it carefully, but I don’t know what else can be the problem. Can I turn on the MacBook without the power button, so then I can understand if the problem is the upper case cable? Any other suggestion? Thank you!
Most probably is the upper case to logic board cable not being correctly seated. I generally use a piece of Kaptan Tape o secure it in place. See step #5 of this guide. MacBook Core 2 Duo Upper Case Replacement
I’ve dealt with this problem before, and yes, I believe it’s caused by damage to the top case connector, specifically when reconnecting the top case to the motherboard. One particular page in the ASD manual (https://www.manualslib.com/manual/887401…) for the MacBook caught my attention, and I think it might explain why I’ve had issues with my keyboard or power button not responding after I’ve reinstalled my top case.
