## Installation

Laptop works mostly out of the box with a recent Linux kernel (>6.1.x). Keyboard does not work in older versions.

## Audio

Its ALC294-powered headset/internal microphone port does not work out of the box. This workaround can be used to enable the headset microphone.

## WiFi/Bluetooth adapter

Its Mediatek MT7922 pcie card has some issues such as not being detected after a restart. Booting into Windows/disabling fast startup/modprobing mt7921e sometimes fixes the problem.

## Power management

The screen brightness is set to max after a restart/logout. This workaround can be applied to save/restore brightness.
