Why do some keys in the laptop not work (esc, tab, caps lock, ctrl, 1, q, a, z)?

Question

Keyboard

Hi, I'm a graphic and motion designer. Once I was working in cinema 4d and I had to render the work done. I had to wait a long time for this because my computer was not that good. I started rendering and went to bed. After 1-2 days, my keyboard sometimes did not work, and sometimes not. I didn't pay attention to it at first. After some time, this situation began to repeat itself frequently. Some keys sometimes work sometimes not. I checked by connecting a USB keyboard, all keys work there.
For more details laptop model: HP, 15-bs085nia, Core i7 7th Gen, Radeon Graphics
Thanks in advance!

Answer 1

It looks like one line has been knocked out in the keyboard matrix. It is treated either by reconnecting the cable (if you are lucky), or by replacing the keyboard (about 2-5k rubles)

Answer 2

It is possible that the laptop was loaded for a long time due to temperature, something happened to the keyboard
