Razer DeathAdder V2 X Hyperspeed - Normal operations using bluetooth, but doesn't work via dongle

The mouse was working perfectly on the 2.4GHz dongle, but then it started dropping connection intermittently. Now it has stopped working on 2.4GHz altogether. Note the mouse is 6 months old.

Bluetooth still works fine, and Razer Synapse detects the mouse properly when connected via Bluetooth. However, when I switch the mouse to 2.4GHz mode, Synapse shows the device as turned off.

I have already updated the dongle to the latest firmware, but the pairing utility does not seem to do anything. It doesn’t complete the pairing or restore the 2.4GHz connection.

I also tested the mouse and dongle on another PC, and the issue is exactly the same, so it does not seem to be related to my computer or Synapse installation.

Could you please advise on the next steps? Is there a way to reset or re-pair the mouse and dongle properly, or could this be a dongle or hardware issue?

Thanks.

Hello there, ​@Hjudeh!

 

Thanks for alerting us about this. It seems like we are dealing with a hardware fault right here. When and where did you purchase your mouse? Let me know via PM along with your device’s serial number so I can validate it in our database and for proper documentation.
