My split x2 charges both batterys to 100%, but when i use the laptop only battery 2 drains, so battey 2 (in the keyboard) drops to 0 the keyboard stops working and battery 1 still shows 90-100%. Is there a setting to make it run both batteries down equally. plus i dont get a low battery warning because when battery 1 is 100% and 2 is 0% it shows 50% battery life.
