Same here on a Dell Inspiron 3593, Bios never updated, version V1.1.0, ubuntu 18.04. It started suddenly one or two weeks ago, previously running without problems.
Reboot always works, complete shutdown and boot within some seconds by power button mostly fails. On 2021-05-14 there was some updates, one of them probably causing this: grub-common:amd64 (2.02-2ubuntu8.21, 2.02-2ubuntu8.23) grub2-common:amd64 (2.02-2ubuntu8.21, 2.02-2ubuntu8.23) grub-pc-bin:amd64 (2.02-2ubuntu8.21, 2.02-2ubuntu8.23) grub-efi-amd64-bin:amd64 (2.02-2ubuntu8.21, 2.04-1ubuntu44) grub-efi-amd64-signed:amd64 (1.93.24+2.02-2ubuntu8.21, 1.167~18.04.1+2.04-1ubuntu44) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883785 Title: intermittent boot failure dell inspiron 3593 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1883785/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
