Hello, the samsung laptop in question is Samsung NP530U3B, it's a kinda an old work laptop which i use for software testing, but the interesting thing is that the keyboard works normally if I dont press (Esc, F1-F12, Fn lock, insert, delete, backspace and Left Shift) If I press these selected buttons the whole keyboard will
"shutdown" you wont be able to type nothing, but if I press the power button and then back on so basically sleep mode and then wake up, the keyboard will work unless I press the buttons as mentioned above.
First thing i would suggest you check is the keyboard settings in windows -
Click on the Start Menu. ...
Click on Settings.
Click on Time & language.
Click on Region & language.
If these are incorrect and pressing one of the keys is trying to input an unrecognised character thats where it could be causing a problem.
Did not change anything, but when I was testing the keys I accidentally pressed one key that was working and another one that didnt, what happened was the key that was working got "stuck" it kept on repeating the letter
