Reboot Your PC

After several hours of nonstop use, our computer will begin to temporarily cache information from all of the operations we perform. These files are essential to our PC’s operation, however, occasionally they become corrupted due to random flaws or malfunctions. It eventually prevents all of our hardware from working properly, so it won’t go away until you restart your computer.

As a result, please reboot your system once before attempting any of the preceding solutions to see whether the problem still persists. 

Uninstall Keyboard Driver

Have you lately updated the driver for the keyboard on your computer? If you have recently upgraded your keyboard driver, you should be aware that the change may have some unforeseen issues. And thus, until you corrected it, the Logitech MX keys weren’t lighting up or reacting. But to fix this, you should uninstall the keyboard driver or revert to the prior variant, and here are the steps you need to take:

When asked, select “Ok” and restart your computer. After the computer has restarted, the necessary drivers will be downloaded and installed automatically.

Restart the HID Human Interface Service

Human Interface Devices are a specific kind of system peripheral that is meant to be operated by humans. Therefore, it’s possible that you’ve accidentally turned off this feature on your PC and will need to restart the relevant service.

Update BIOS and Chipset Drivers

Keeping your BIOS up-to-date is vital since it determines how well your device functions. Many of us fail to realize the importance of keeping our BIOS and chipset drivers up to date. The BIOS system does get updated automatically while upgrading Windows, but it still has to do this manually on occasion.
