i have an issue with my hi12
if i boot on battery in full charge, the tablet starts but it shutdowns just before android os
if i boot it with charger connected, it boots correctly but it shutdowns after few minutes.
it is the same with windows 10
android softwares battery health checker give no error.
i have already installed the bios random shutdown fix.
i have check the solds points of the - and + connector of the battery and its ok.
is there a solution without change the battery ?
