Hello together,
I found myself an old Mavic Mini that doesn't turn on at all anymore.
Batteries are fine and fully charged - i tested them with my own Mavic Mini.

Unfortunately the power button is broken off the mainboard and i can't seem to figure out how to re-wire the button to at least be able to test for further damages.


Is there any way to get technical information about this board?
Thank you in advance

At a guess put the switch in place and touch a soldering iron to what appears to be two blobs of solder at 5 to 5 but the solder tabs on the switch would need to be intact. Post photos of the bottom of the switch and
any contacts you can see and
the switch sitting in situ.

If it's a simple switch and the solder tabs are broken then you might be able to find a suitable replacement on the web, it would probably need to be "non latching".

Hi there. Sorry for this unpleasant experience. I'm afraid that you may consider sending the unit in for a proper diagnosis. You may contact our support team to start up a ticket at https://www.dji.com/support . Thank you for your understanding.

These are the requested images
As you can see two pads are ripped off the pcb.

Sending it in to technical support is no option for me

If the solder points have ripped off the circuit board then the only thing I can think of  is to trace the damaged tracks to their next solder point ( if there is one ) and solder 'flying leads' to each such solder point, then glue the switch to the board and solder the loose end of each flying lead to the appropriate contact on the switch.
However I think you would be very lucky to trace the remaining tracks reliably.
Unfortunately I think you will need to be very lucky to make a successful repair.
I would also suggest you use a multimeter etc. to check the connections between the solder points on the switch, I see what I think are three but there might be four. Check the connectivity with the button depressed and not depressed.

It might be better to
1) trace the circuits but mark their "next solder points"
2) solder the "flying leads" to the switch.
3) Glue the switch to the board and
4) solder the loose end of each "flying lead" to the appropriate "next solder point".
You will have to judge that for yourself.

I would also ask about this repair on an electronics repair forum ....... if you can find one. If you do find one include the photos shown in this thread.
The repair of this circuit board is probably more their forte than it is a 'drone repair'.
