When I lock the case or write the "systemctl suspend" command, the screen turn off, the system freeze and the laptop keeps turned on. I need to force the laptop turn off and on again. There are some cases when it suspends without issues, but most of the time it freezes. There are some workarounds for issues like this one but they are mostly for laptops using nvidia graphics. I am not sure how to provide debug information about this issue, but I can give it if someone tells me how to do it.
