So I definitly frown the charging circuit of my poor Z and now come to the big question :
I'm pretty sure repairal won't be covered by warranty as it's entirely my fault (accidentaly reversed polarity from my third party charger), so how much will sharp(brando) charge me for repairal ?
I'm actually thinking about buying an external charger and think I could wait with such a solution 'till I can buy a new Z if repairal cost is too expensive to be interesting (if half the price of a new unit it won't be interresting, better be using this one as a spare unit for testings and buy a new one)
