Make sure that your program is currently selected for use. The device should be programmed for ‘front’ and ‘active.’ You can activate it by clicking anywhere inside the program. To make sure the program is responding to your commands, try typing.

There could be debris on or in the laser sensor.

Mouse LED lights aren’t working properly.
Launch Razer the razer application on you computer and check to see if the device needs an update. It is possible the device is behind software-wise and might need an update itself to allow the LED lights to work.
Plug mouse into different USB port, as it is possible the USB port is not recognized by the computer. If you try it plugging it in to another device and it works there, then the device you have originally tried to get the mouse to work with has a faulty USB port.
