Windows 10: Keyboard alphanumeric characters stop working randomly

I have had this problem for some time already. Randomly, the pc stops anwering to alphanumeric characters; however, special keys enter, esc, shift, etc still work. I can't type anything on any search bar Windows or we browser or text editors I have only tried notepad, but I assume word and similar programs would do the same. When this is hapenning, it also blocks character reception in videogames namely I have had it happened in League of Legends, and I assume it would happen with other games, but I haven't tried it with other games specifically. I believe this is a software problem be

:)

 

Current active users that are friends

The other reason I suggested this is that users can add characters to their username that are not alphanumeric (e.g. user*). This confuses things somewhat when looking at the list.

 

Keyboard randomly stopped working

My built in laptop keyboard stopped working after the computer randomly turned off by itself.

(Laptop is a Lenovo Ideapad).

I have tried:

Uninstalling drivers and scanning for hardware changes to reinstall them.

Entering safe mode (computer wouldn’t even start in safe mode).

Entering the BIOS to see if there were any changes I could make there (there weren’t).

Now I am getting Code 19 and Code 12 errors for the keyboard in Device Manager.

I’ve tried all troubleshooting steps on many websites, and nothing works.

External keyboards work when I plug them in.

Please help!!

 

Keyboard randomly stops working after sometime

Hi,

The keyboard is working in BIOS mode however in the Windows mode it stops, this could be happening because the System files of the OS maybe corrupt. Run a SFC scan and check. Follow the below steps:

• Press Windows + X
• Choose "Command prompt (Admin)"
• Type " sfc /scannow"
• Press Enter.

Let us know if this helped to fix the issue.
