My M650L mouse lost connectivity. [br]
New battery. It just stopped moving in the middle of operation.[br]
To my luck(?) I have another same model, and it functions as expected, on the same laptop.[br]
I had a chat with the Logitech support, and they promised me, they would help, but when all their usual basic guides didn't help, they stopped responding.[br]

Did anyone manage to fix the famous connectivity problem with this mouse?
