- Wait for the scan to finish.
- Once the scan is finished, restart your computer. Try connecting the keyboard and check if it lights up. If it doesn’t, then move to the next step.
- Repeat Step 1 and type the command in the terminal and hit Enter: DISM/Online /Cleanup-Image/restorehealth
- Wait for the scan to finish.
- Once the scan is finished, restart your computer and check if the keyboard lights up.
Fix 6: Update your USB Port and Keyboard Drivers
If you are still facing the issue, consider updating your keyboard drivers. Drivers are responsible for the proper functioning of your keyboard. Outdated drivers can cause the device to malfunction, and your keyboard might even stop working. The same goes for your USB ports as well. If their drivers are outdated, the USB ports will not work properly. Therefore, it is essential to keep your drivers up to date. Follow these steps to update your drivers:
- Right-click on the start menu and select Device Manager.
- Find your keyboard driver in the list and right-click on it.
- Select “Update driver” and click on “Search automatically for drivers.”
- Then, expand the “Universal Serial Bus Controller” entry.
- Right-click on your USB drive and select “Update driver.”
- Click on “Search automatically for drivers.”
- Do the same for all your USB drivers.
- Finally, restart your PC for the changes to take effect.
- Once your PC boots up, connect your keyboard and check to see if the backlight is now working.
If you’re still having problems with your Razer Blackwidow keyboard not lighting up, then it might be a hardware issue. Contact Razer support and ask them for a replacement. You can even visit a service centre if that’s available in your locality.
