Error 2107-0114 and discharging fast

So, I bought a dead switch, after unplugging battery and plugging back in, left to charge for hours and it charged fine but sometimes turns off with the error 2107-0114. I left on sleep overnight at 70% and found it was dead in the morning. It has since charged fine but given me the same error and fast discharging. I have checked the capacitors around M92T36 and all seems good around that. I have read that reflowing the WiFi chip may help sort the error out? Any help would be fantastic.
