Out of the blue, battery 2 (the battery located in the keyboard) stopped charging and is now permanently at 0%. When the Surface book and the keyboard are connected bettery 1 (the battery located in the screen is charging normally).
I tried replacing the battery in the keyboard, but it didn't help. What do you think could be the solution? I tried to find a replacement GPU board without success.
Es esta una buena pregunta?

Hey. I’m not sure what you mean by gpu,but as long as the surface tablet works fine,you can probably get a new keyboard. It’s really down to the possibility of a power management issue in the keyboard. This can be a loose connection somewhere,a damaged component,etc. You may want to look into buying another keyboard for it.

As an electrical engineer i am trying to hunt down a similar problem. i have an undesirable voltage on my battery cells and my laptop charger is not propagating through the board. so i am trying to go through the chips to make sure things are turning on but some how 15V is creating a 3.3V rail. but my input protection mosfets are not turning on to allow the 15V to go to the battery charger.

Ok I have the same issue that the keyboard stopped working, so (don't laugh) I pulled the keyboard of the surface, spit on the terminals and rubbed very hard to kind of clean them, and walla my keyboard now works.... :-) Hope this works for others its worth a go...

Hi Luca, I have the same issue. Did you manage to find a solution?
Thanks!

Nope. It needs a replacement of the logic board inside the keyboard. Couldn't find a replacement logic board and a new keyboard is expensive considering that it's an old machine. You find from now and then second hand keyboards around, but didn't bother to look for it actively.
