In connection with what, the following laptop keyboard keys can periodically turn off?

Question

Keyboard

There is an Asus N550JV used in stationary mode. After an unusual transportation for him, he began to turn off the same keys. The liquid did not spill, there was no strong mechanical impact.

The problematic keys are highlighted in the image with a red circle (" F8 ", " SHIFT (L) ", " * ", " - ", " 0/insert ", " UP ", " DOWN ", " SPACE ", " B ", " N ", " Z ", " CTR(L) ", " ALT(L) "
It is interesting that if you press one of these keys many times, then it starts working, albeit only after one time. The rest of the keys also start to work through time. If you give the laptop a "rest", then again all the keys stop working until you press one of them many times.
Using the shift and space as an example, I disassembled the keys, there was no debris under them.
In this regard, the following questions:
What binds these keys so that they behave the same way?
What could be the reason for such a problem?
What to do?

Exactly the same problem with the same model.
The bend of the cable from the keyboard, which is located under the battery, caused the failure of the group of keys. The issue was resolved by straightening the inflection and folding the cable in other places.
Everything worked!
