Fast charging less than 3H but limited autonomy, I do not see why ... Asus K53SV / Seven Family / Core I5 / 8GB ram, on the train, WiFi connected via my mobile, I see only 2.5 episodes Gears therefore slightly less than 3H autonomy, damage (So a star in less). Obviously the original battery was not much better! I wish all TGV do not offer every time a tap (that works), but I'm off topic ...
