11th Gen BIOS 3.07 + Windows 10 and (11 Alpha) driver bundle

Installed 3.07 by EFI startup.nsh, up and running without immediately noticeable loss of function.

As other users have noted, my GRUB bootloader was lost by the firmware after the install.

Unlike the above, I avoided chroot (since that risks a mess and I prefer to be on my actual system when I can):

  1. boot to recovery medium with a UEFI shell (e.g. Ubuntu install image; note that this appears to be necessary since the shell doesn’t seem to be available through the BIOS interface)
  2. locate your ESP partition among the initial output of the shell
  3. type FS0: or FS1: or FSx: where x is the partition number of your ESP and FS is whatever disk it’s on, then ls/cd to your grubx64.efi file and execute it
  4. once back in your usual Linux environment, reinstall the bootloader (see erock’s post quoted above for that, or GRUB - ArchWiki, or force-reinstall grub and hope your distro’s install hooks work right)

Similarly unexpected experience: starting from a charge (100%) above the set charge limit (80%) resulted in battery discharge over time on Linux (Arch; was cursorily looked at on Ubuntu 20.04.3 LTS but not rigorously) and upower reporting discharge while the laptop was idle and connected to the stock charger.


The set-charge-limit-at 80% → see 81% appears to be likely an OS issue, at least on Linux. upower reports 80% on the dot while all my other indicators show 81%. It’s possible that upower is idiosyncratic, though.


I’ve seen some bizarre behavior in the side indicator lights’ blinkiness. Context is provided below; weird bits are in bold.

Notation:
< : my action
> : result from the laptop

< set charge limit 80%, run laptop from 100%
> laptop discharges to 80%, showing some forgotten indicator light pattern
< run laptop at 80% (seeing 81%)
> laptop blinks amber
< unplug laptop, run to 75%
< set charge limit 100%, run laptop charging to 82%
> laptop solid amber charge
< reboot, set charge limit 80%, run laptop
> laptop keeps charging from 82% to 85%
< disconnect laptop, reboot several times, run discharge to 80%
< plug laptop in, run laptop at 80%
> laptop shows solid amber light

I haven’t attempted to reproduce this yet.
