> 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.
The error message give the impression that you had the power cable disconnected and battery at 12% while trying to update the firmware? When I tried this, the power cable was plugged in. (Possibly the error message is just misleading. I regret not paying close attention when I did that the first time, so I didn't notice any error messages that might have been displayed, as long as they didn't require a keypress to dismiss.) > Have you ever entered BIOS (or Setup) and pressed "F9". It will excute "Load default"(or "Setup default"). No, I haven't. > 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. Oh, that is interesting information and it explains one mystery at least! -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
