There can be several cases if the laptop keyboard does not work. First we must check if it is a physical  or hardware problem  or if it is due to software . This will be key to fix it.

How to fix it if it’s a software problem

Turn the laptop on and off

Sometimes the simplest solution is the most effective. For this reason, we recommend that the first thing you should do if the laptop keyboard does not work is  to restart the computer  to verify that it is not a specific problem.

Check Windows Components with Command Prompt

If our laptop doesn’t work because of the software, the first thing we should check is  that all the Windows components work correctly. To do this, we will do the following:

  • In the search bar at the bottom left of the screen, we write: CMD or Command Prompt  and run it as Administrator.
  • Once the window is open, we execute the following command: sfc /scannow
  • This process will check all Windows components. When finished we must restart the computer.

Update keyboard drivers or controllers

 To update the drivers or system controllers , we will do the following:

  • In the search bar at the bottom left of the screen, we type: Device Manager .
  • We access the  Keyboards or Keyboards section.
  • We select the devices that are within the section and by right clicking we give  Update driver. 

Reinstall keyboard drivers

If updating is not enough, we will try to reinstall the keyboard drivers. To reinstall the drivers, we must do the following:

  • In the search bar at the bottom left of the screen, we type: Device Manager .
  • We access the  Keyboards or Keyboards section.
  • We select the devices that are within the section and by right clicking we give  Uninstall driver. 
  • We reboot the laptop so that Windows will automatically install the  uninstalled driver  at the next power on/boot.

Check that the keyboard is configured in our language

The fact that the keyboard does not work well can also be because  it is not configured in our language. To check/configure it, we will do the following:

  • In the search bar at the bottom left of the screen, we write: Regional and language settings.
  • We check the language that is selected and if necessary we change it.

Install an antivirus os drivers or keyboard drivers

Viruses can affect all the components of a computer, so it will be essential to run the antivirus to check that there is no malware or malicious file   affecting the operation of our laptop’s keyboard.

How to fix it if it’s a hardware problem

If the problem is not with the software, it is probably a hardware problem (failing wiring or keys) and things get complicated here , because it will probably require a specialized service and professional technicians to solve the problem.

Check if it is a hardware problem: we enter the BIOS with the keyboard

To check if it is a hardware problem, the first thing we can do is enter the computer’s BIOS as follows:

  • We turn on the equipment and immediately press: DELETE + F2 , F8 or F12. If the laptop enters the BIOS, then the keyboard is fine and works properly and we surely need to format the computer. 
  • If we cannot enter the BIOS following the steps above, then surely the problem of the keyboard not working is due to a hardware error.

Two solutions if the problem is hardware

This is the most recommended option,  especially if the laptop is under warranty . Not only could we damage the computer, being able to take it to a specialized service at no cost , but when we open the laptop, we could lose the guarantee .

And if it is not under warranty, we should never open our laptop if we have not done so before, since it is such a delicate material, any error could render the rest of the equipment useless.

If we are not used to doing this kind of thing, our recommendation is that you leave it in the hands of an expert.
