2] Update or re-install the Keyboard driver
Maybe you need to reinstall the keyboard drivers. You can temporarily enable the on-screen keyboard or connect an external keyboard if you are not comfortable without a keyboard. You may read this post on how to use the Windows computer without a keyboard or mouse for further details.
Now to update the driver, open Device Manager from the WinX Menu. Now under ‘Keyboards’, you will find your laptop’s keyboard. Right-click on it and select ‘Uninstall’. If you are not sure about your laptop’s keyboard, you can uninstall all the keyboards.
Restart your computer and check if you see its driver installing automatically. If not, again open Devices Manager, right-click on Keyboards and select Scan for hardware changes to install it.
After the driver is installed, check if the keyboard starts working.
Alternatively, you may choose to directly download your Keyboard drivers from the manufacturer’s site and install it.
3] Run Keyboard Troubleshooter
Run the and see if that helps you.
4] Change the Repeat Rate
Open Keyboard properties > Speed tab > Locate Repeat delay setting.
This setting denotes the time Windows waits after a key is pressed to activate it again.
Move the slider a bit towards ‘Long‘ and see.
5] Turn off Filter keys
If you notice a short lag from the time you press a key and a character is displayed on the screen, then you need to disable Filter Keys. What Filter keys do is basically ignore repeated keystrokes to make typing easier for people with hand tremors. But it can cause problems sometimes for normal or fast typing speed. To disable filter keys, go to Settings and then Ease of Access. Select the keyboard from the left menu and find an option to disable filter keys. This might solve your problem.
These were a few tips that can get your keyboard working. Other than these you can try the hardware diagnostics tool that may have been installed on your laptop by your manufacturer itself. If nothing helps, then the best option is to carry the laptop to a certified repair center.

If the keyboard is working but not taking the inputs properly, you can perform a Clean Boot and check. Once there, you can check whether the keyboard is working fine or not. If it is fine, then probably there is some third-party software or service hindering with the keyboard in the normal state, which you will have to identify.
8] Reset the BIOS to defaults
Reset your BIOS to default and see if that helps you.
