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):
- 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)
- locate your ESP partition among the initial output of the shell
- type
FS0:
orFS1:
orFSx:
wherex
is the partition number of your ESP andFS
is whatever disk it’s on, thenls
/cd
to yourgrubx64.efi
file and execute it - 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.
