RAZER BLACKWIDOW V4 PRO 75% Some keys are unresponsive | Razer Insider
Skip to main content

Hi, my Razer BlackWidow V4 75% has a problem where the number row with backspace, arrow keys, ctrl alt, function enter, and delete suddenly stopped working. I’ve tried replugging, different USB ports, testing on another PC, checking for stuck keys, and trying reset combos (though Fn itself is dead) — nothing works. Has anyone had this issue before? Is it worth opening up to check for a cracked solder or damaged trace, or maybe theres something i can do?

Hello there, ​@everAlloyOrangefuture333!

 

We’re leaning toward a hardware fault right here. Try to reinstall its drivers by following the steps below:

 

1. Press Windows + S on your device to open the Search bar.

2. Type in “Device Manager” and hit Enter.

3. Go to "Keyboards" or "Human Interface Device".

4. Right-click on the Razer BlackWidow V4 75% and select Uninstall device.

5. Restart your computer to completely uninstall the drivers.

 

The drivers will automatically reinstall after your computer restarts. If that didn’t do the trick, then shoot me a PM along with your device’s serial number so I can validate it and check for other workarounds.
