This I can do, but I would like to avoid if possible, because of the time and wear. Regards, -- Nicolas George signature.asc Description: PGP signature

[1] This version doesn't require a product key or activation. Some BIOS\Firmware updates could be installed from WinPE (or WinRE) environment, but I doubt this one from Acer could run on WinPE, because it is bundled with a driver, along side with a few executable binaries and shared DLLs. Another viable option, because you've got a drive image of preinstalled Windows 10, is to save an image of current drive and restore from the image with preinstalled Windows OS. And after BIOS is updated, restore from the saved image with latest data. Clunky solutions, but I think there are no other options, because apparently Acer hates GNU-Linux. :\ [1] https://www.microsoft.com/en-us/evalcenter/evaluate-windows-10-enterprise -- With kindest regards, Alexander. ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ Debian - The universal operating system ⢿⡄⠘⠷⠚⠋⠀ https://www.debian.org ⠈⠳⣄

On my new Acer TravelMate Spin B3, running recent Bullseye, I have noticed a strange battery drain when the computer is powered off: it loses about 1% of the total battery charge every hour, which makes a quarter of the battery in a day. The drain happens when the computer has been powered down with poweroff or an equivalent. I have checked, and it does not happen if I power down with a long press on the power button (after halt). Therefore, it is a sign of something staying powered with the normal kernel shutdown. I have checked that wake-on-lan, wake-on-RTC-clock and similar features are disabled in the setup. Does anybody have an idea about what could be the culprit or how to investigate? Thanks in advance. Probably something to do with USB-Charger feature.
