Question about ASUS ROG Flow X13

The pen does not need to be connected. It interacts capacitively with the touch screen, i.e. contactlessly via an electromagnetic field at the tip. Only one battery (AAAA) needs to be inserted or the battery already inserted in new devices needs to be activated. As a rule, the manufacturer places a small, insulating plate or foil on a battery pole for this purpose, which must be removed before the device is put into operation.
