DeathAdder V2 Pro not turning on / working in 2.4GHz mode, works fine wired

Hi everyone,

I am experiencing an issue with my Razer DeathAdder V2 Pro.

The mouse works completely fine when connected via the USB cable, but whenever I switch it to the 2.4GHz wireless mode, it does not respond, does not turn on, and shows no signs of power (no sensor light or LEDs).

Details & troubleshooting done so far:

  • Fully charged the mouse via cable before testing.

  • Tested on different USB ports directly on the PC (no USB hubs).

  • Synapse detects it normally in wired mode, but loses connection immediately once unplugged and set to 2.4GHz.

Has anyone experienced this before? Is there a pairing utility fix or firmware update step I should try, or is this likely a battery/hardware failure requiring RMA?

Thanks in advance for the help!
