Installation

Before installing it is necessary to modify some UEFI Settings. They can be accessed with F2 when booting.

Dual boot

Please note that changing from "RAID" to "AHCI" can break the default Windows installation and require a complete reinstall. Usually running windows own startup repair utility however fixes this issue in most cases. Another alternative is to follow this guide.

The reinstall can be done through the Dell recovery in the UEFI if needed.

Once you used the startup repair utility or have reinstalled, Windows should boot normally in AHCI mode and without error. Then one can proceed with typical dual boot setup.

Audio

The device is equipped with 2 bottom firing speakers and 2 top firing speakers. The bottom firing speakers work out of the box, however the top firing speakers do not work. This is due to incorrect default pin output and DAC configuration - the pin 0x17 is by default disconnected.

As of August 2022 a kernel patch fixing this issue has been created, and it is under testing. It is confirmed to build with kernels 5.19.2 and 6.0. It will be committed to the main kernel tree soon as testing is finished and it is expect that the patch will be merged in kernel 6.1. Until release, the Patch which is accessible at this link can be applied during a custom built of a kernel. Even with the patch, the top speakers start playing sound with a ~0,5 second delay after the bottom speakers.

Sound from the headphone jack suffers from popping sound when audio starts and stops playing.Internal microphones and external microphones work with no issues.

Power Management

See Hibernation for kernel parameters & initramfs configuration.

S3 Sleep is not supported. S0ix however works reasonably, loosing roughly 0.5% battery per hour. "RAID" needs to be changed to "AHCI" for S0ix to work. Without S0ix activated the laptop looses around 2% battery per hour.

NVIDIA's open source driver reliably disables the NVIDIA card. It is possible to use the proprietary driver, however as of August 2022 when it is used the NVIDIA GPU sometimes randomly turns on, drawing approximately 8W of extra power.

Fingerprint reader

See fprint.

The fingerprint reader works well if it used in one operating system only. Attempting to use the device in several operating systems results in disconnection of the device and refusal to accept fingerprints.
