I can confirm that with the generic 5.11 kernel shutdown works correctly - the laptop powers off completely.
Workaround: - Installation of Generic kernel sudo apt install linux-generic-hwe-20.04 Note: It may be necessary to also manually install the corresponding linux-modules and linux-modules-extra packages. - Reboot into the Generic (5.11) kernel from the GRUB menu - Removal + Purging of OEM kernel dpkg -l | grep linux-oem Perform a 'sudo apt remove --purge' on all listed packages (in my case there were three listed) as well as on the associated linux-modules package. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1940665 Title: Lenovo Carbon X1 9th gen no longer powers off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-oem-5.10/+bug/1940665/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
