Some laptop keyboard keys do not work, or different combinations of characters appear when typing, what solutions can there be?

Question

Keyboard

A couple of weeks ago, I didn’t flood the laptop much, I don’t remember what, but I didn’t disassemble it and wiped what was on top. Everything worked and I no longer paid attention to drying.
But yesterday the keyboard started behaving strangely. Namely, to print numbers together / after letters, for example: ts2v5, etc., when you click on the capslock, a unit was printed, spontaneous input began.
I decided to remove the keyboard, check the cable, I didn’t see anything suspicious, wiped the cable with alcohol, returned everything to its place and, it seems, everything started to work as it should.
But today, when I turned on the laptop, the keyboard did not work at all. I took out / stuck the cable many times, the keyboard worked every other time, but for a short time.
As a result, I noticed that everything works when the keyboard is connected, but not inserted into the slots, i.e. rests only on the train. If you assemble a laptop, then it again works for a small amount of time with periodic lags in the form of inoperability of some keys and combinations.
Actually, everything. Are there any options other than replacing the keyboard or contacting the service?
Thanks in advance.

Answer 1

Disassemble the keyboard (and they are usually non-separable in laptops). Repair yourself, close (see item 1). Rejoice.
