So I'm having an issue with Zorin OS 16. When I try to shut my laptop down or put it on sleep the screen turns black but the power button light stays on and the fans keep going. The laptop stays in this state until either the battery dies or I long press the power button.
I first experienced this on the Core version which was installed but also experienced it on the Lite version on a Live USB.
I'm not having this issue with 15.3 Lite which I installed after the issues started with 16 Core.
It's an HP pavilion laptop with a dual core AMD APU (cant remember the exact model) and an AMD R7 M340 GPU
Did you try playing with the options under Settings -> Power?
If I recall, some of them are set to Suspend as the default outcome if you press your power button. Change that to shutdown and see what happens.
Note: I used a live usb with 16 Lite because I've reverted back to using 15.3 Lite since I dont have this problem. Even after pulling the live usb out the laptop stayed on (fans going, power light on) and after 5 or so minutes I had to hold down the power button
I have done a websearch which may help you for installed Z16, but running on Live USB may be different.
Have a look at these. The first will lead you to the second. I have no idea of knowing if this will help you or not.
Sorry to ping both of you like this but I was wondering if either of you could shed some light on this. A few people have been having this issue but made a post on the Zorin sub reddit instead of here
I've tried shutting the laptop down using systemctl poweroff, sudo shutdown and the shut down button in the menu and setting the power button to shut down.
Maybe unrelated, but i was having the same problem just a week ago. Zorin won't shutdown, no matter what. Been trying everything i could find, like turning off suspend, setting power button to poweroff, using 'poweroff -p' command, editing GRUB, but to no avail. Even livebooting Zorin 16 Lite failed to power off my laptop.
Turns out, for me, it was something to do with the latest Linux kernel. It was upgraded from 5.11.0-40-generic to 5.11.0-41-generic a week ago. Booting with 'Advanced options for Zorin' and selecting 5.11.0-40-generic kernel does the magic and managed to shutdown the laptop for good. Now i'm defaulting to boot with 5.11.0-40-generic kernel with Grub Customizer.
My laptop use AMD A4-9125 processor, might have something to do with that probably?
