Razer Deathadder v2 turns on but doesn't move cursor.

I am having similiar issue with my Deathadder Essential. It was fine untill yesterday, but now the mouse pointer wont move from the corner. Other mouses are working fine in my pc. Tried to clean install Synapse again but NOW even thats not installing no matter what I try. Help!

Only RMA if the mouse is not working on another PC.

What is “RMA”?

I completely removed everything and checked the circuit board but no damage to be seen at all in the Deathadder but in my Viper Mini 2 small components were burned. I tried plugging it into my computer and it started to burn and smoke.

seem to have the same issue for my DA essential, but my button still works and lights up. but it just doesn’t move after an update in windows 10 to my laptop. not sure what is the problem here.

Same here what worked for me is use the on screen keyboard go to ig you need it or use a different mouse in the meanwhile just for this settings>windows update>advanced options>recovery>advanced startup and chnage your restore point go back to what you where before the issue started and keep in mind the mouse should work while in bios since no apps have started yet unless its a hardware issue this is a good way to rule out if its a software issue.
