Surface book 2 battery won't charge via keyboard

[aina_zo]

Hello everyone
I have a SB2, the battery on the tablet part charges only when plugged in directly with the connector
If it's in laptop mode and plugged in, it will say battery 1 30% (ie) and in use / battery 2 40% and charging
Even though it's on the charger, battery 1 will deplete and it will shut down with battery 2 fully charged
Anyone has a fix for this issue?
Thanks

Looks like thé charge won't go through
Everything else works fine (keyboard, dgpu, ports,...)
