Lenovo Yoga 3-14 80JH won't power up if battery connected

[pfrcom]

Only way this will power up is disconnect battery from motherboard JBATT1, attach charger, then while keeping Novo button pressed, switch charger on

Once it's going, if I reconnect battery it will charge, and Win10 will eventually show 100% charged

I can also reboot Win10, which happens normally

But if I shutdown Win10, I have to repeat above performance to get it going again

FWIW, Win10 is a clean install starting from secure erase of SSD:

MX Linux also booted without issue

Any tips? - I'll need handholding to troubleshoot

I've now removed the motherboard, to find it's a BTUU1 NM-A381 Rev:1.0

So now I'm following-up here: https://www.badcaps.net/forum/showpo...6&postcount=13
