Occasional keys are not synonymous after change (laptop)?

I've already swapped the keyboard for a new one, but some do not work again. The funny thing, though, is that the two keyboards are different. Some that did not work with the old one work now and vice versa.

What can I do, thanks.

Go under devices manager and search the keyboard, then try to update the driver times

So with me sometimes many keys did not work, then I have all cables that went off the keyboard carefully pulled out everything cleaned with my compressed air spray can, reconnected. Then I have everything updated and tada Funzt, except when I make benchmarks from higher temp. Then strike the Numpad
