Keys on keyboard get pressed after a while. Delayed key press.

[Ruturaj Gole]

The keys 'j','k','l' and ';' only appear on the screen if they're pressed for a while. Sometimes it's a few seconds, 8-9 seconds at most. But weirdly, if for once one of those gets pressed, all of those keys start working properly until they're in use for that while. But only for the while until they're in use. After that, I again have to long press one of those to get them working.

For example: I've started the laptop. I open a text editor and try to enter the letter 'j'. But it doesn't get entered. So I keep it pressed for a few seconds and then it appears. Suddenly, 'k','l' and ';' start working properly as well. I type the document I want to and when I'm done, I wait for a few minutes. And then I find that those keys have stopped working again.

Things I've tried: Reinstalling the keyboard driver.

Model: Lenovo Thinkpad z570

Thank you for your assistance.

P.S I'm talking about the integrated keyboard that came with the laptop.

It is your keyboard and not the problem of software.
