Keyboard issue: 3 simultaneous keys

Question

Hello,

I have a problem with my laptop keyboard:
I cannot press three keys simultaneously from two adjacent columns

Explanations:
I call a column for example: the row of keys, 1-A-Q-W
or even 5-T-G-B

My computer does not register the X key for instance if I am already pressing two keys from two adjacent columns like A and S.

This means I cannot press:
-A Z and X at the same time
-Y J and N
-Z E and C
-...

Is this normal? Is there a driver problem?
Thank you for your thoughtful advice.

Standard keyboards can’t handle more than 3 simultaneous key presses, so that’s completely normal.

However, if you have a gaming keyboard (Razer, Logitech G15 and G19), then it’s a driver issue.

Hello Choco,  Thank you for your reply, it is indeed a standard keyboard, which apparently can only handle a maximum of two keys pressed simultaneously.

Make sure you don't press ctrl + alt + del while typing.

yes  the only macros managed by these keyboards are Ctrl+Alt+Delete or Alt+Tab or Alt+F4 etc...

Hello
I had seen that the on-screen keyboard in Windows (accessibility options) allows you to perform Ctrl Alt Delete by clicking the keys one after the other, but I don't know if it can do that for other combinations.
