No Power after upper case repair
I had spilled some liquid on a A1278 unibody MacBook 13". Immediatly shut off power and let it dry 2 days.
It did work fine but the keys on the keyboard got very sticky and it did not get better using them a lot. So I decided to clean the key board, but after taking it almost wholly apart, decided against that avenue and ordered a new upper case from ifixit.
So today I tried to exchange the upper case. It should be noted that I have the german version and of course I got an US upper case as spare part. After again taking it apart and putting everything in the new upper case, the thing won't start.
Battery is almost fully charged. MagSafe Adapter LED is green without battery inserted and orange once battery is put inside.
I tried the resetting thingy with 5s Power Press without any power attached (incl. battery taken out) and also the immediate PR-whatever reset with alt-cmd-p-r. To no avail - it won't start, just charge the battery.
Could it be that the US upper case won't work with the german logic board?
Is this a good question?
