Hi, Today I had my tablet in a cold car trunk for like half an hour, the battery was already empty. After I arrived to work, I waited about 10 min. until the tablet was at room temperature and then connected the charger and tried to start it. Nevertheless, it worked for like 20 seconds and then suddenly stopped. Tried again, the same. I let the charger on for 5 minutes and then it started normally. My conclusion is that the charger (and the SP3 power system) cannot support running the SP3 without a battery having at least some minimal charge. The same thing happens with my Asus T100, only much worse. For once, I think that the charger connector of the SP3 is of lower quality than the SP2. Magnet is weaker and the pins are very thin, the SP2 had a strong magnet and solid pins. So choosing a possible alternative charger with higher current I'm not sure would solve this problem.
