I bought the m650 mouse to use on both my personal and work laptop - using the usb connector on personal and bluetooth on work laptop. I turn off the personal laptop and turn on the work one. I expect the mouse to find the bluetooth connection, or by shortly pressing the connect button, for it to connect via bluetooth. However, it seems that switching between the two computers is not possible unless I add it as a new device. This is very inconvenient. Why make a mouse with two modes of connection if it can only be connected to a single device?
