820-01987 Not detecting battery after changing keyboard

[Soji]

System was detecting battery before Keyboard was changed, after keyboard was changed, it won’t detect battery, system will come on with charger plugged, but without charger, there’s haptic feedback, the PPBUS voltage is 11.56V instead of 12.6V, but system won’t come on…
Immediately charger is plugged, it will come on by pressing power button. We could we have done wrong??

"PPBUS voltage is 11.56V instead of 12.6V"
Did you ever find a battery with 12.6V?
How can be fully charged then?

If you get 11.56V, battery is enabled, so probably battery bus has been damaged somehow, or the data flex is broken.
