im also facing the same issue i tried various tried various things but it didnt worked When I try to shut down Ubuntu, the system goes through the shutdown process, the screen goes black, but then the computer immediately restarts instead of powering off completely.
This appears to be a firmware/BIOS compatibility bug. I have already performed extensive troubleshooting, and none of the following steps have solved the problem: Updated BIOS: The laptop's BIOS/Firmware has been updated to the latest version available via fwupdmgr. Tested Multiple Kernels: The issue occurs on the standard Ubuntu kernel (6.8.0-84-generic) and also persists on a manually installed newer mainline kernel (6.16.8). Tried Kernel Parameters: Numerous kernel boot parameters were tested in GRUB, including reboot=pci, reboot=force, acpi_rev_override=1, and acpi_osi=! 'Windows 2020'. None had any effect. Checked System Logs: The system shutdown log (journalctl -b -1) is clean and shows no errors. The operating system appears to be sending the correct power-off command. The issue seems to be that the firmware is not correctly executing the final shutdown command from the Linux kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1434978 Title: HP Zbook 14 G2: systems restart after shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1434978/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
