Do not respond when you move the mouse or click on the buttons. I have my laptop has Bluetooth, but there is no mouse or nano-receiver button sync with the laptop. I searched and searched the Internet to try to driver detective key find an answer, but nothing to see. Can someone please help me? My experience with Dell laptops, I also found that sometimes an external USB mouse not because of certain characteristics is detected with power and USB. Holiday on the mouse, turn off the laptop and remove the battery for two minutes. Machine turn on and see if the mouse on the magic appears. .
