So I have an "Acer Nitro 5" laptop and it has always had a bug since I got it.
In fact:
If the laptop goes into standby / power saving mode after 10 minutes of non-use, you can no longer get out of standby, which means no matter what I press or something, it remains a black screen until I then press the laptop by pressing the off button for 10 seconds Switch off button. It is usually like this, in about 80% of cases, rarely you can get out of the standby mode by pressing the space bar.
What could it be?
Is probably because of poorly made drivers or a poor implementation of the drivers.
Try to update the chipset drivers.
Otherwise: disable the quick start

If none of this helps, I would simply do without the StandBy. With an SSD, such a system boots very quickly. So: better shutdown and restart.
I know the problem, the best thing to do is turn it off, set everything to 4h.
My age does that too, even a new installation didn't help.
