## Sleep/Suspend

S3 suspend will work out-of-the-box as long as Intel microcode is loaded.

### Touchpad

On kernel 5.3 and lower, the touchpad will stop working after waking from suspend. THis can be fixed by reloading the `i2c_hid` kernel module on wakeup.

## Graphics

As long as xf86-video-intel and xf86-video-amdgpu are installed, PRIME will work with the default configuration. The GPU will automatically power off completely when not in use.

All video outputs (HDMI, USB-C) are connected directly to the Intel UHD 620 Graphics.

Intel GVT-g is compatible with this laptop.

## Audio

Note: The 4-channel audio and microphone work out-of-the-box as of 5.6.14-arch1-1 using the latest git version of PulseAudio (version 13.99, soon-to-be released as 14). You can install that version using pulseaudio-gitAUR). For the released version of PulseAudio (13 and older), please use the indications below.

To get it working with PulseAudio 13 and older, follow those steps:

1. This laptop requires firmware in order for the soundcard to work. See Advanced Linux Sound Architecture#ALSA firmware.

2. Configure PulseAudio's to load Alsa modules with the correct `device` and `channel` settings, by adding these two lines to `/etc/pulse/default.pa`:

    /etc/pulse/default.pa

    ...
    load-module module-alsa-sink device=hw:0,0 channels=4
    load-module module-alsa-source device=hw:0,6 channels=4

Note that Alsa card numbers can change when adding more audio devices (like, connecting a USB headset or a docking station). To ensure that index '0' always maps to internal audio, add `snd slots=snd_soc_skl_hda_dsp` to your module loading options.

3. Reboot, then use `alsamixer` to increase the "master" channel level of the `sof-hda-dsp` sound card (use the `F6` key to switch cards). If you do not see `sof-hda-dsp` in `alsamixer`, you may need to add `blacklist snd_hda_intel` and `blacklist snd_soc_skl` to `/etc/modprobe.d/blacklist.conf` and reboot again.

4. If the output sounds tinny, try muting the "speaker" item in alsamixer.

## Function keys

Pressing and holding the fn key actually makes the function keys emit regular F* keysyms, so it works in a sort of inverted fashion for the top row keys. There is no physical 'Insert' key.

1. The key is visible to `xev` and similar tools
2. The physical key has a symbol on it, which describes its function
3. systemd handles this by default

Pressing the F11 (`XF86RFKill`) also results in:

    kernel: atkbd serio0: Unknown key pressed (translated set 2, code 0xf8 on isa0060/serio0).
    kernel: atkbd serio0: Use 'setkeycodes e078 <keycode>' to make it known.

    kernel: atkbd serio0: Use 'setkeycodes e078 <keycode>' to make it known.

Pressing the F13 (share screen) results in:

    kernel: atkbd serio0: Unknown key pressed (translated set 2, code 0x6d on isa0060/serio0).
    kernel: atkbd serio0: Use 'setkeycodes 6d <keycode>' to make it known.

    kernel: atkbd serio0: Use 'setkeycodes 6d <keycode>' to make it known.

Pressing the F14 (accept phone call) results in:

    kernel: atkbd serio0: Unknown key pressed (translated set 2, code 0x66 on isa0060/serio0).
    kernel: atkbd serio0: Use 'setkeycodes 66 <keycode>' to make it known.

Pressing the F15 (hang up call) results in:

    kernel: atkbd serio0: Unknown key pressed (translated set 2, code 0x65 on isa0060/serio0).
    kernel: atkbd serio0: Use 'setkeycodes 65 <keycode>' to make it known.
    kernel: atkbd serio0: Unknown key released (translated set 2, code 0x65 on isa0060/serio0).
    kernel: atkbd serio0: Use 'setkeycodes 65 <keycode>' to make it known.

## Touchpad

The touchpad itself and the lower pair of buttons are visible as the "SYNA3091:00 06CB:82F5 Touchpad"; upper pair of buttons belongs to the "PS/2 Generic Mouse", however. "SynPS/2 Synaptics TouchPad" and "SYNA3091:00 06CB:82F5 Mouse" are visible, but do not produce any events.

## Additional hardware

The laptop contains an M.2-2242 B-key slot, designated for the LTE modem. Alternatively, one could install an additional SATA SSD.
