The problem arises as a result of the design of the MacBook. The section of the board with the ports and the section near the fan slot are grounded via the metal shield on the lower case. Screws in these areas complete the ground circuit for the logic board. If a logic board is tested while not in the case with these screws installed, the result can be a short in the logic board.

If you lose firewire, USB, audio or ethernet, the only thing to blame is the logic board. Because there are many components of the logic board, numerous possible symptoms indicate logic board failure. Any one of these components can fail and leave the others intact. If you lose the use of another component of your computer, such as the display, battery, or even power, and replacing the apparently non-working part didn't fix the problem, it is possible that the logic board may need to be replaced Core Duo or Core 2 Duo.
My computer will run for about 10 minutes after the power adapter is unplugged but then it will shut off. Do I have a bad battery? Sounds like you do have a bad battery. How old is your computer?

But there is still a open question for me left. Logical spoken, to reassemble the hole MacBook Pro is just the reverse way how to disassemble it.
Okay so far so good concerning the clips and screws, but how do I fix the "protecting tapes" and "sheet" on the keyboard connection etc.? It would be very helpful, if I can have a hint ore even some further pictures "how the reassemble" the protecting parts "tapes" and "sheet"! Since early days it is not restarting when I choose too.

How can I tell if my iMac logic board is dead
I am normally force shutting it by that long press hold on power button, and then I power it back up. Now, at these few times that it is surprisingly restarting, it's not coming up with airport on. So I normally shut it down again, but properly, and then up again, and when I make shore that the airport is there, and I simply continue working: Never checked this thing in a lab, did all different kind of test and updates, checks, repairs and tricks It works fine for last 2 years and half except heating and a slow cooling fan, and some slow performance from now and then, and those cracks in the the body and the battery life Well I guess i need to replace something, and i would love the self home made solution: Bueno, many thanks in advance if you take your time to answer that even read that , cheers, long living and prosperity.

Voted Undo. Score 6. Can you get into single-user mode by hitting command-s during boot? I cant boot into any mode at all I have tried all the PMU resets I could find online and no joy It wont even start up - it is like pressing the power button with the electricity in the house off From what I can find out, this model iMac is not covered by any extended logic board warranty like the G5 iMacs, so this is now an ex-computer.
