Laptop Adapter Spark Causes Power Outage in Room: Troubleshooting Electrical Issues

The problem is as follows:
Yesterday, when connecting the laptop adapter to the contact, the plugs (automatic) blew out with a big bang, but the electricity in the sockets and the light in the whole room was turned off, which was a bit exotic for me. After switching the automatic plug (only one dropped) nothing has changed because there is still no electricity or light.

Using my very basic knowledge of electrical installations, I checked the socket when using it, it blew out the plugs and it was slightly sooty, but the cables seemed to be whole, I cleaned them a little and twisted, then checked the socket which is first in the row at the entrance to the room and there everything was already flawless.

What could be the problem that I missed? Thank you in advance for your response.

There are no fuses in the corridor outside the apartment?

There are fuses, probably 2 if I remember correctly, but there is electricity in the rest of the apartment.

Get an electrician from the cooperative and that's it. You have to open the cans and check them one by one. Is there voltage in front of security in the apartment?

Tension is everywhere, but not in one room, today I will contact the administration of the cooperative.

Laptop power supply OK?
It is possible that it is damaged, and causing a short circuit, the fuses were activated and the less tightened cable in the box burned at the same time.

I had a similar event once, i.e. after a short circuit, restarting the circuit breaker did not restore power.
It turned out that the fuse itself was damaged. I replaced it, it works.

I know a similar situation. Namely, the building is quite old, aluminum installation. Connecting the laptop's AC adapter caused a short circuit and the wires were burned out. At the same time, the fuse in the power supply has blown as I dismantled it later.
So the search should start with the room supply can.

The power supply works, I'm just waiting for the electrician, if I find the fault, I will let you know what it was about

I struggled with such a problem living in a block of flats from 1979. The circuit of the sockets was routed without cans, in the corner by the floor, from contact to contact, aluminum installation, the wire was burning in one of the sockets and there was no voltage on the further part of the line.
If you know the order of the sockets in the circuit, you only need to look at the cable coming from the socket with the voltage on and going to the next socket.
Make sure a working socket is on the same circuit where "S" fell.

It turned out that we had an additional external plug about the existence of which no one knew and it burned down, topic to be closed
