Keyboard issue

Recommended Posts

Posted · Original PosterOP

Hello, I use external keyboard with laptops. Two keys 'c' and '3' print weird things. When I press 'c' it prints:




And '3' prints:


The keyboard was not somehow damaged. I have tried to use it with different laptops with MacOS, Linux, Windows and event with Samsung S8. The same problem for all the devices. Also i have tried to remap keys with SharpKeys and KeyTweak, no result. Both keys print above text.


On the screenshot you can find what happens when I press those keys. White means which keys are also pressed with 'c' or '3'. And the order in the top. Does anyone know how to fix it?

Membrane keyboardIt sounds like there is a short inside the keyboard causing many keys to trigger at once. 

Maybe open it up and clean it?

What kind of keyboard is it?

It is membrane keyboard from SpeedLink (https://www.speedlink.com/en/Gaming/TYALO-ILLUMINATED-GAMING-DESKSET-DE-LAYOUT.html)

I have already disassembled and cleaned it, but there is no result.

And if you goolge "536l4jk1-=`" you will find similar questions. For example this (https://forums.techguy.org/threads/my-keyboard-glitches.1224844/). I have tried to contact the guy who posted it, he does not reply.

So, I think it is not problem with keyboard itself. It is problem with its software like virus or something like this.
