For a general overview of laptop-related articles and recommendations, see Laptop.

## Accessibility

The UEFI offers one mode of operation, GUI.

The GUI can be navigated to some degree via the keyboard. `Left` and `Right` arrow keys to move the selection and `Space` to activate.

Note Blind users may want to request the help of a sighted person to change UEFI settings

## Firmware

fwupd does not support this device yet and likely is not going to.

Lenovo support page for this model only provides .exe installer for UEFI updates. There is no option in the UEFI itself to select a binary blob from USB stick.

### Updating UEFI

Note Make sure your device is on AC power

A workaround is to install the UEFI from Windows PE. A common choice is Hiren's Boot CD. Boot into the live environment, download the update file and install it.

### Secure boot

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.

## 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.

## RDSEED32 is broken

With Linux ≥6.17.7 an RDSEED32 error message can be seen during boot:

    RDSEED32 is broken. Disabling the corresponding CPUID bit.

Error message is related to AMD-SB-7055/CVE-2025-62626 which affects AMD Zen 5 processors.

Fix will arrive in future UEFI versions: Lenovo Security Advisory: LEN-208435

At the moment of writing, UEFI version for Yoga Pro 7 14ASP9 is TBD with target availability 2026-02-27

### LUKS passphrase entry appears frozen

RDSEED32 error message causes Panel Self Refresh (PSR) timing issues so that it seems like it is frozen on the LUKS passphrase entry.

Disabling it fixes the issue.

## Panel Self Refresh

PSR can cause flickering and random freezes/crashes on AMD Ryzen AI 300 Series Processors and can be disabled to fix the issues.
