Updating UEFI
Note
Make sure your device is on AC power
A workaround
is to install the UEFI from

. A common choice is
Hiren's Boot CD
. Boot into the live environment, download
the update file
and install it.

Warning
Installing with Microsoft vendor keys is recommended as there are not any reports indicating if it is fully safe yet. No Option ROMs in the below output provides some confidence, however it is up to the user as you risk bricking your device.
The firmware does not have any options to install keys through it, to install keys you can use tools such as sbctl. No Option ROMs appear to be present as per testing with:
# cp /sys/kernel/security/tpm0/binary_bios_measurements eventlog
# tpm2_eventlog eventlog | grep "BOOT_SERVICES_DRIVER"
See
Secure Boot
for more details.
Issues
Speakers
This laptop by default uses the wrong playback device,
defaulting to card 0
instead of card 2 which is the Realtek ALC287. This causes it to only use the bottom two speakers and not the top two woofers. We can fix this by manually changing the device used by creating
/etc/modprobe.d/alc287.conf
options snd-hda-intel model=(null),alc287-yoga9-bass-spk-pin
and rebooting.

Disabling PSR fixes the issue.
