## Accessibility

The BIOS offers two modes of operation, GUI and Simple Text.

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

For full keyboard support switching to simple text would likely be better.

That can be accomplished by:

- Selecting and activating Config on the left side under Setup
- `Right` arrowing until the drop down to the right of Setup UI is selected
- active the drop down and select Simple Text
- `F10` (save and exit)

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

## Hardware

### Video

#### Brightness control

As of kernel 5.9 use the native brightness controller, use the `acpi_backlight=native` kernel parameter.

### Audio

PulseAudio seems to work fine without manual intervention, but the ALSA audio device chosen by default may not be correct. You may need to change the default device.

    /etc/asound.conf

    defaults.pcm.card 2
    defaults.ctl.card 2

You should remember to unmute the volume.

### Webcam

If the integrated webcam is not accessible as `/dev/video*` and does not appear in the output of `lsusb`, installing upd72020x-fwAUR may help.

## Firmware

fwupd does not support this device yet.

### UEFI

It is recommended to run the latest UEFI version, which is currently 1.36.

The "BIOS update" can be downloaded as an ISO image from the X13 support page and loaded to a USB stick.

Additionally, there is a UEFI option for customizing the Power profile that by default is tuned to `Windows 10` and is recommended to be set to `Linux`. This setting has been shown to reduce issues with #Power Management.

Note: According to Lenovo, the Windows mode may be preferred even under Linux.

## Power Management

Various issues have been reported with resuming from suspend. In order to mitigate them follow the best practices described in #UEFI.

On systems that use full-disk encryption with sd-encrypt it might be preferred to switch to using the `encrypt` mkinitcpio hook.
