Laptop doesn't turn on after it suddenly went off?

My Lenova laptop went out of nowhere a few minutes ago. I played something and everything went black out of nowhere. The LED lights also went out, and stayed off too.
I had the laptop on for a relatively long time because I played on it.

Then I went to eat (during which it was actually on) and when I came back it was suddenly out. However, I'm sure it was on. I switched it on again, but it went off again after about 20 minutes.

I have already tried to turn it on again by holding down the power button for a long time. Nothing happened.

I think it's overheated, but I think that's weird because it's a gaming laptop and I've left it on for a long time.

Can someone help me or explain how to get it working again?

Hmm, difficult

Have you already plugged it in?

And is it warm when you put your hand on it? So when it's warm, I would let it cool down completely. Then switch it on and just leave it on without you doing anything. What you can then do is monitor the temperatures, e.g. B CPU-Z or MSI Afterburner. If it then gets warm, the thermal paste may no longer be good: /

If you know something, just report again.

Thank you very much! Let it cool down overnight while it was charging, and now it's working again.

I'm glad, no problem.
