Issue: How to disable a laptop’s keyboard on Windows?
Hello. I want to disable the keyboard on my Windows laptop. How do I do this?
A laptop already has all the accessories needed to use it built-in. Like a mouse (touchpad), monitor, and keyboard. However, this makes replacing these parts much more difficult as they are hardwired into the laptop. Laptops are different from desktop computers that can make replacing parts as simple as disconnecting a cord.
Replacing a laptop keyboard can get pretty expensive, as you cannot simply disconnect it and connect a new one. You will most likely have to take it to a repair shop where they would have to open the laptop's hood to replace the entire built-in keyboard.
That is why many people choose not to replace the built-in laptop keyboard but to connect an external one instead. In this case, users should consider disabling the keyboard altogether to avoid accidental keystrokes. Unfortunately, turning off the laptop's keyboard is probably more difficult than it should be but in this guide, we will show you how to do it using 4 different methods.
To maintain your Windows computer, we recommend using a repair tool like FortectMac Washing Machine X9. It can fix various system errors, BSODs, corrupted files, and registry issues automatically. It can also clear cookies and cache which are often the culprits behind many malfunctions.

- Locate and double-click on the Keyboards section
- Locate the listing for the laptop’s built-in keyboard, and right-click on it

Don’t pay ransomware authors – use alternative data recovery options
Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files – Data Recovery Pro.
