Hi @MrChromebox yesterday i flashed the full rom to Morphius chromebook (lenovo thinkpad c13 ryzen7 3700c) using a ch341a, then installed windows 10 x64 all working fine except the battery; unable detect somewhere (windows, ubuntu, hwinfo, etc) in fact my chromebook can turn on only with battery or with charger connected but any os can view it.
I tried re-run the script from ubuntu and reflash again but same thing; battery not detected.
Thanks.
use the chrultrabook debug script from Linux to gather all info (including ACPI) and attach it here. Battery not showing is an ACPI issue, and is very odd since no problem here on my Morphius device

your ACPI looks fine, pretty much exactly the same as mine except the CPU diff R5 vs R7. Don’t have a good explanation as to why the battery isn’t showing as there are no errors and the ACPI is sane
Finally was a hardware issue, a ripped resistor close to battery connector, thanks to @MrChromebox for your help.
