I just got this new mouse and while it works in wireless radio mode with the dongle, it will not pair via Bluetooth. I am running Windows 8.1 on a Lenovo Yoga 11s with Bluetooth 4.0. I'd rather not use the dongle obviously. Why do I get a driver error when trying to pair and why can't I find any drivers for this on the Lenovo website?
The mouse has to be in mouse mode and in wireless mode also! Press and hold the L,R and the middle button(not the windows one (the middle touch have 2 buttons underneath)) then switch to Bluetooth mode without releasing the 3 buttons, after 5-10 seconds you will see the orange light and after that the mouse will be able to pair.
