Method 3: Reboot your computer
Pretty basic fix and works most of the time. Try rebooting your computer and check if the issue is resolved. Most of the Logitech keyboards stop working for some unknown reason and rebooting the Pc will get them back working.
Reboot and Reset are two different operations. Reboot means restarting the device while resetting means deleting all the data on the device. So, make sure you reboot your device and not reset it.
Method 4: Change the USB port
Try changing the USB port and check if the keyboard is working. The USB port you are currently using might be damaged and due to that reason, the keyboard might not be turning on.
If any of the USB ports on your PC/ Laptop are not detecting the Keyboard, then try checking it on some other PC for clarification. If the keyboard is not working on any PC then it’s damaged for sure.
Method 5: Update the Keyboard Drivers
Keyboard Drivers are essential drivers because these are the one that makes the keyboard compatible with a PC/Laptop. Sometimes, if the keyboard drivers are outdated, the keyboard may not work or malfunction. To avoid these kinds of issues, always keep your keyboard drivers updated.
Steps to update Keyboard Drivers:
Type device manager in the Windows Search box and then open the application from the results or use the shortcut Ctrl+Shift+ESC
Once Device Manager appears on your screen, go to the keyboard category and click on it to expand.
Right-click on your keyboard device and click on Update driver from the list of options.

Select the first option Search automatically for updated driver software.
Now, wait until Windows finds and installs the latest version of the keyboard driver on your computer.
Don’t forget to restart your computer so that all the changes will be applied.
Method 7: Reinstall Windows
Sometimes the issue is not with your keyboard, but with Windows itself. So reinstalling Windows will be the best option if no other method works for you. You can also reinstall the windows manually, but that’s a very hectic task and time-taking process.
Note: Make sure you have backed up everything before you perform this action. Also, don’t interrupt during the whole process otherwise, the windows might get corrupt.
