Hi Marius. I spent some time following the steps and testing them, but the phenomenon you describe didn't happen. After charging battery to 12% and updating by "fwupdmgr upgrade", computer restart -> show "Check power failure,please insert the power source or charge the power" -> power on normally.
Except for the information you provided, I'd like to confirm other details: Have you ever entered BIOS (or Setup) and pressed "F9". It will excute "Load default"(or "Setup default").Althrough it seem insignificant, that may cause the issue you mentioned. By the way, althrough you charge battery to 12%, the bios upgrades still failed due to low power. When the battery is above 50% ,bios will update successfully. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1900121 Title: firmware upgrades remove the ubuntu boot loader from EFI boot vars To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fwupd/+bug/1900121/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
