## 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

### Bluetooth

Bluetooth doesn't appear to work with the stock Qualcomm Wi-Fi 6E QCNFA765 modem. The modem is an M.2 2230 form factor and not soldered (on the AMD variant of the X13 Gen 2), and can be replaced easily with an Intel AX210.NGW.

### 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.

## Firmware

fwupd does not support this device yet.

### UEFI

It is recommended to run the latest UEFI version.

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. See #Power Management.

Note: According to Lenovo engineer, the Windows 10 setting may be preferred if the kernel supports it.

## Power Management

The UEFI provides two choices for the sleep mode in Config > Power > Sleep State. The Windows 10 mode (s2idle) is recommended, and results in about a 0.5%/hour drain while sleeping. Using the Linux mode (s3) may help if you are running an older kernel.

See Power management/Suspend and hibernate#Changing suspend method.
