Computer never turns off when shutting down or suspending

Ever since yesterday, my PC never turns off when shutting down or suspending. The screen turns black but the fans are still on. I am using Ubuntu 18.04 LTS.

Hi @Magnusmaster

We done some troubleshooting one day with a other user :

Maybe something went out from this configuration after the upgrade.

I hope it can help you start troubleshooting

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"
didn't work.

I tried to update the kernel with the mainline kernel installer but the Nvidia driver failed to build with those kernels.

Hi :slight_smile:
Sad to hear that.
What is your motherboard ?

My motherboard is Gigabyte H55M-S2

If nothing from ACPI settings helped, i can advise you to update your BIOS or try to replace the motherboard battery.
