Hi depotLightKhakifirst452,

I’m here to help. Please check if the issue you are experiencing with your Razer DeathAdder V3 is happening while the Razer Synapse is closed or disabled. Were there any incidents that happened to your mouse before the issue? Is there any noticeable physical damage from the device or cable? PM me the device serial number to verify its model and provide a resolution. Let's continue this conversation in English so I can better assist you. All the best!
