Battery meter always show 100% until dead

hello, i am on unlocked bios, 8100y europe version,
and i cannot flash the normal ec file and this patched ec file.

when charger unplugged, battery always show 100% until dead,
if i am charge to 90%, battery meter is normal.

from device manager, uninstall “microsoft acpi compliant control method battery” still not fix it.

i think my battery meter work normal, until i flashed bios from management to fix fan issue.
“(PS: If you think the minibook’s fan sounds too loud, you can try brushing the BIOS to improve it)”

What should I do ? and i want turn off the fan too.
thank you.

Contact service@chuwi.com , they will give you instructions how to fix it.

I’m a user of M3 version.
I had the same symptoms.
However, drain the battery completely, then charge it 100%.
Repeat 6 to 7 times, the current battery indicator starts normally.
Also, problems with fan can be helpful by looking at the links below.

all my problem is solved now.

i am successfully flash my EC.
my flashdisk is fs7

cd fs7:
and than
