The PC does not switch back on after standby

This morning I was taking notes on my lenovo yoga 520, I left it unused and then went on a black screen. So far so normal. To turn it on I press the power button and he first goes into standby, and then reignited (I do this because I have the screen turned and I can not touch the keyboard, so the only key is the power button). Now it is already the second time that the LED is on, but the screen does not light up ...
Obviously to turn it on again, I had to press the power button brutally.
So I searched journalctl and 10 minutes before the mess happened I found this -> https://hastebin.com/enedehokak.sql
Can someone help me understand what happened?

I am far from an expert in these matters, but from looking at your posted outputs my first thought is your video drivers have not been set up correctly.

Please post the output of:

inxi -Fxxxz

Another thing that often causes issues with suspending correctly is your wifi adapter. If you can disable your network adapters in your bios temporarily you could at least rule that out as a cause.

I can not disable the wifi from bios, but in any case I could not try, because the problem does not always manifest...

Intermittent problems are very difficult to troubleshoot. That will make finding the cause much more difficult. Hopefully someone may have some suggestions for you.

The only suggestion I can think of is to install and test kernel 4.18 to see if there is any improvement on a newer kernel.

I'm having a similar problem on my desktop after upgrading to 4.18.9. Most of the time system wakes up fine after suspend but sometimes it's dead frozen and I have to do a hard reset.

If it's your network components read this thread where I've been helping to try and get this problem resolved for another user. The best way to resolve this problem is by writing a service.

Read this thread:

The problem is not suspending but to wake up after suspend, I would've thought it was a different issue?

Resuming from suspend problems are often related to issues with the video driver or network driver/ network components.

It can affect either the ability to enter sleep or resuming from suspend.
