Is the power supply interrupted again and again with the laptop?

The question relates to experienced electricians:

The power supply to my laptop keeps getting interrupted. At first I thought it was my old laptop, but now I have a new one for 1000 euro. And the problem is there again: the light suddenly turns orange to indicate that the laptop is charging. But it's plugged in all the time, it sometimes loses up to 40% of its power, do I have to worry and have an electrician come? I set everything to never with sparstrom and so on, so it can't be because of that.

Tried a different socket? ^^

I did it yesterday, but can't something go wrong with the other one at some point? What if she keeps cutting the power?

So my crystal ball is on vacation.

You give absolutely no information about where the device is e.g. Is plugged in.
Whether you have tested the power supply on other sockets.
Whether somewhere else flickering lights, power outages etc. Have already happened in your house…
How should someone help you over the Internet?

Then why should what you burn have the other socket checked by a specialist

Since this is probably a two-pin Euro plug that is sheathed with plastic on the rear section of the contact pins, pull it out a few millimeters until you feel a slightly increased resistance. - Then contact should be established.
If you take a closer look at the picture, you will also understand why this is so.
