## Installation

See #Accessibility on how to change UEFI settings, disable Secure Boot and boot an Arch installation medium.

System boot and everything works, see #Video for possible visual glitches.

## Accessibility

The UEFI firmware settings can be entered by pressing `F2` repeatedly during boot.

### Navigation

The interface can be fully navigated and controlled with a keyboard and mouse. Up and down arrow keys let the user choose categories, settings items within each category and values for settings. Left and right arrow keys let the user leave and enter a category, settings item or value picker. The enter key can also be used to enter a category or enter and leave an item's value picker. Settings can be saved and the system restarted by pressing `F10`.

### Secure Boot

In order to boot an Arch installation medium, Secure Boot must be disabled in the UEFI settings. Once disabled, press `F12` on the next boot to enter the boot device menu and select your Arch installation medium.

## Firmware

This laptop is not supported by fwupd. You need a Windows installation in order to update UEFI.

## Video

If you see sporadic graphic glitches, add `amd_iommu=off` as a kernel parameter.

## Power management

### CPU performance scaling

This laptop's AMD Ryzen 7000 series CPUs support the new AMD P-State performance scaling driver, which is driven by the `amd_pstate` kernel module. However, currently the generic `acpi_cpufreq` driver takes precedence when booting the linux kernel. In order to activate the `amd_pstate` module, the `acpi_cpufreq` module has to be blacklisted and the `amd_pstate` module has to be explicitly loaded.

### System performance mode

There are 3 modes available: Intelligent Cooling, Extreme Performance and Battery Saving.

## Audio

The factual accuracy of this article or section is disputed.

Reason: Editing files in `/usr` will break on each update as the file will be overwritten: provide a proper `/etc/asound.conf` configuration. (Discuss in Talk:Lenovo Yoga Pro 7 14APH8)

This laptop has 4 speakers: 2 tweeter and 2 woofer, by default only the tweeters work.

The volume switch only on-off, to correct that you can edit:

    /usr/share/alsa-card-profile/mixer/paths/analog-output.conf.common

    [Element Master]
    switch = mute
    volume = ignore
    ...

From kernel 6.6.7 this workaround are not necessary due this kernel patch officially merged:

https://lore.kernel.org/all/20231207182035.30248-1-tiwai@suse.de/

## Keyboard

The built-in keyboard does not work with kernels before `5.20`. Linux `5.20` and `6.0` include a patch that fixes the keyboard on all AMD Zen systems.
