Okay, so after trying several different trackpads, none worked. I had somehow given up hope that the MacBook would work, but finally I connected the battery and suddenly everything worked again. I didn't have a battery in my Macbook the entire time I was testing it. But if I understand it this way, the system only runs at 100% when all components are installed.

The device are works now...

oh ok wow?! I'll test it after work. The battery has already been removed because it doesn't work. Would it work normally if no trackpad is connected?

Hi

I have now a 820-4924 (with a i7 and 16GB).
I would like to get the device working again for me.

The Problem is the Device comes to me with a "dead" ssd. I tested on a other 820-4924 (i5-8gb) board and the MAC OS Installation stopped working with this SSD.
Well i hope/guess its was a easy peasy Fix - New SSD And its working again.. But No!

I don't know exactly how the procedure should start. But the LCD panel goes dark - then the "chime"(?!) sound comes and only 2 or 3 seconds later the apple comes.

it doesn't...

The repair is done! Successfully.

I Take a Donor Board and use the R Area from this Board.

Now i wanna try to upgrade a 4GB modell to 8 GB ^^.. ( i have to buy now a BGA178 Stencil)


Thank you all!! Peace from Germany!!...
