It's not a bluetooth mouse, maybe it's older iteration was as there are cutouts for bluetooth pairing but under the sticker. Also if the dongle is not provided any power(I mean that if your device is not switched on) then the mouse will not work(show red light) even if it's switch in underside is in the on position and in this case the mouse will try to search for the dongle providing such signal that it activates the mouse and will result in battery drain at a higher rate than usual.
