Good afternoon, I was researching and I did not find a safe solution for this tablet so I was willing to experiment. take a Chinese battery that had stored and remove the tablet where the regulator goes and perform the same action with the inflated battery remove the card where the regulator goes and temperature sensor by undoing the battery and solder the original card to the Chinese battery , when checking with the multimeter this did not give me voltage but still connect it to the tablet and connect the charger and this began to load when I turned it on the charger this gave me a 60% charge compared to the old battery that always told me that it had 100% even when I just plugged it so I removed the charger and the tablet did not turn off was kept on. I hope my invention does not have consequences for the tablet or if someone already carried out this action and I do not happen to orient me. thank you and best regards to all !!
