Magic Keyboard 2 can not connect it via Bluetooth
My Magic Keyboard 2 can not connected via bluetooth, can only connected via usb, it just like dead totally after unplug usb cable.
Before this happened, I were cleaning it, and claped it a little bit, then it can not connected via bluetooth, usb is fine.
I wonder if the wire between battery and board is disconnected or something.
Is anyone knows what is going on ? Do I need to tear it down ?
