I had a Razer DeathAdder Pro V3 (wireless) suddenly stop working—it was completely dead. No response when plugged in, no wired mode recognition, and pressing the power button did nothing.
After some trial and error, I found a fix that sounds strange but worked for me:
- Flip the mouse over and hold down the power button for 5–10 seconds.
- This seems to force a reboot or override mode.
- A white light started blinking, and suddenly the mouse came back to life.
- After that, I was able to charge it and use it normally again.
This issue happened randomly while I was using my computer. I stepped away for about 5–10 minutes, and when I returned, the mouse was completely unresponsive—no clicks, no lights, and no reaction in wired mode.
I'm not sure how long this fix will last, but if your DeathAdder Pro V3 suddenly dies, try holding the power button for 5–10 seconds. It worked for me!
Hope this helps someone!
