Hi! I'm not sure if this is a problem in the classical sense (i.e. a bug), but for me it is in some ways.
I don't understand what is the function of the middle (off) position of the mode switch on the bottom of the Razer DeathAdder V2 Pro is, but maybe that's just because it doesn't work well for me. In this position, the wireless mode is supposed to be turned off, so it only works with a cable. This would make sense if it doesn't work in the other two positions, but it also works when the cable is connected. The reason I'm sure it's wired in this case is because I use the receiver with the additional dock, plug the cable into that (and the other end into the computer), and then transfer the cable from the dock to the mouse, so the receiver is not available in this case.
It could be that it is not charging in this [off] position, so I can use it with the cable without charging it unnecessarily. But not so, if the cable is in, the mouse is charging in all three positions of the switch.
This simply means that the middle position is redundant, but this could not have been the manufacturer's intention. But then what is the purpose? If it turns out, then so does the fact that the device is faulty.
Thanks in advance.
