Bluetooth keyboard (Keychron K12) connected but not typing after hibernate/few sleeps

I recently got a Keychron K12. It's pretty nice. What's not nice though is that my laptop (ThinkPad X230 with stock BT daughterboard) doesn't like it after a certain amount of time. Symptoms appeared soon after getting it, so the culprit might have been there from the get go symptoms: None of the keys are registered by the laptop (modifiers, alphanumerical, Windows) Local macros (e.g. backlight off) still work Can type on phone with keyboard after stops working with laptop Goes away after a restart (once it did with a hibernate iirc) Problem specific to my w10 install (works with mint install
