Laptop stops responding?

Hi, had my laptop in sleep mode for several hours, now the monitor shows me that it is not getting a signal. Have already removed the hdmi cable several times and plugged it in again. Now I wanted to restart the laptop, since I can't see anything on the laptop screen either, I have to switch it off differently. Unfortunately, it does not react when I press the switch-off symbol. What should I do?

"Wake up" laptop. Just briefly press the power button!

I did, nothing happened

Wait and try again tomorrow.

I had that a few weeks ago, arranged with the repairman that he would pick up the device in the evening, and when I cleaned it up shortly before, he suddenly left.
