Make sure the cables aren’t fried before we dive into the fixes. Examine the keyboard, cable, and connecting port for signs of wear and tear. If the keyboard looks good from the outside, there are possibly some internal issues or some setting faults within Operating System.
However, an on-screen keyboard can be activated as a substitute.
Navigate to the All Programs menu by clicking the Windows logo.
Scroll down and click on Settings.
View Accessibility.
Under Interaction, select Keyboard.
Under the On-screen keyboard, access keys, and Print screen, enable the On-screen keyboard.
Now that you have enabled the on-screen keyboard, try the following solutions to fix your keyboard.
Replace Batteries
When a wireless keyboard’s batteries grow low, it may not register a keypress immediately. If you feel that the OS is not detecting the keypress, consider changing its batteries. You should always keep your rechargeable wireless keyboard charged.
Disable USB Power-saving Mode
After a predetermined amount of time, the operating system will off power to a USB port to conserve battery life. When this option is selected, the keyboard will periodically become inaccessible. If the keyboard has been inactive for a while, the USB port might not be active, but it will once you push a button.
Simply taking the USB connector out of the port and putting it back in will resolve the issue. To avoid using USB selective suspend altogether, you can turn off the feature.
To access the Run command prompt, simply press the Windows key plus the letter R on the virtual keyboard.
To access Power Options, type powercfg.cpl and hit Enter.
To modify your current electricity plan, go to the Settings tab and click Change plan settings.
Select the Advanced Power Options button.
Expose the USB options by scrolling down.
Add a selective suspend option via USB.
Choose to Turn it Off.
Select Apply, then OK.

USB selective suspend’s effect on a device’s ability to save battery life is similar to those of other power-saving methods. Having this feature activated means that the computer will power off any unused hardware. To stop your gadget from preserving battery life, do as instructed below.
To open Device Manager, right-click the Windows icon.
Improve Keyboards.
It’s a good idea to double-click the keyboard you’re using right now. If you’re still having trouble figuring it out, try unplugging the keyboard and seeing if the offending item reappears on the list. Put the keyboard’s plugin now.
If you want your computer to stop using its power when it’s not in use, you may disable this feature under the Power Management menu.
Disable Filter Keys
By turning on filter keys, your rapidly repeated keystrokes are disregarded. Users with mobility issues, such as those with Parkinson’s disease or arthritis, may benefit greatly from this. In general, it can prevent the operating system from registering key presses, creating the impression that the keyboard is unresponsive.
To access the system configuration menu, press Windows + I on the virtual keyboard.
Select the Keyboard under the “Accessibility” menu.
You may now turn off the Filter keys.
Turn-On-Off-Filter-Keys
Uninstall Companion Application
In addition, a keyboard’s functionality could be unexpectedly halted by a keyboard’s associated programme. These programmes are able to do whatever they want with the keyboard’s microcontroller. Any trouble with the keyboard could be the result of an incorrectly set app.
Try removing these programmes one by one to see if it corrects the problem.
To access the Run command prompt, simply press the Windows key plus the letter R on the virtual keyboard.
Tap in appwiz.cpl and hit the enter key.
Choose Uninstall after clicking the app you wish to get rid of.

Lower High CPU Usage
Even a basic task on a computer can take a certain amount of time depending on the CPU load. The processor continues to complete calculations even at heavy CPU usage. In addition, when the CPU is being intensively utilized, the computer may fail to register a keypress.
In order to have someplace on the CPU for additional instructions, the demanding process needs to be either completed or terminated. To minimise CPU utilisation,
Press Ctrl + Shift + Esc on the On-screen keyboard to enter Task Manager.
If the task manager only displays the active programme without the background process, you can view it by clicking More details.
Select the offending programme that’s using up all your CPU time.
Select End task.
Run Keyboard and Hardware Troubleshooter
Windows’ built-in troubleshooter will investigate and attempt to repair any problems it finds. Issues with the keyboard can be resolved by launching the troubleshooter for the keyboard and hardware.
Using the on-screen keyboard, you may access Settings by pressing the Windows key plus the letter I.
Go to System > Troubleshoot > Other Troubleshooters.
The troubleshooting for the keyboard should now be executed.
After it’s done, hit Windows + R to launch the Run window.
Launch the Hardware and Devices troubleshooter by entering msdt.exe -id DeviceDiagnostic and hitting Enter.
To launch the hardware diagnostic tool, select Next.

Update Necessary Drivers
When attaching a keyboard, it is essential that all of the associated drivers work properly. These include the USB driver, keyboard driver, and Bluetooth driver (if using a Bluetooth wireless keyboard). If these drivers aren’t up-to-date, they won’t be able to communicate with a current OS.
The keyboard can stop functioning inexplicably if this happens. To get the latest drivers installed, please read the instructions below.
To open Device Manager, right-click the Windows icon.
If you use a Bluetooth wireless keyboard, you should update the drivers for your computer’s keyboard, USB hub, and Bluetooth technology.
Clean the Keyboard
Dust under the keys is another common cause of a malfunctioning keyboard. The keyboard has a number of crevices via which dust might enter. The keyboard’s microcontroller could fail if dust gets into it.
Purge the entire keyboard and see if it helps. You may find articles here that show you exactly how to take the keys off and clean the keyboard.
Is It Time to Get a New Keyboard?
If you’ve tried everything else and the keyboard still won’t function, see if it will work on another computer. If it doesn’t fix it, you almost certainly have a broken keyboard. Buying a new keyboard should fix the problem.
