Why is there a delay in input from the laptop keyboard?

Question

laptops

Good afternoon!
There was a problem, on the built-in laptop keyboard, there is an input delay after pressing a key, or vice versa, an additional same character is inserted. It turns out that the pressed key is either not printed or two letters are printed. It’s very inconvenient when you type quickly, it feels like some bus is busy at that moment.
With a keyboard connected via usb, this is not observed.
Comrades zhelezyachnikov, tell me, buy a new clave or is it some kind of controller?
The problem occurs regardless of the installed system. Claudia filled with nothing.

Have you tried disconnecting and connecting the keyboard (at the native cable from the connector, pull out-insert)? If yes, then the next step is to throw another.
