Why does my laptop stop charging while playing games?

Question

Windows

When you start the game, endless sound alerts begin about disconnecting and immediately connecting the charging and the screen blinks. I would immediately understand that this is not enough charging power, but if it happened when I first bought it. But no, there were no such problems before, and yesterday I could still afford to play a rather voracious game like Arma 3.

Answer 1

I would immediately understand that this is not enough charging power, but if it happened when I first bought it. But no, there were no such problems before.

Strange logic.
What is the time of purchase?
Most likely the problem is in the connector or power cable.
