Installation

The Realtek RTL8822CE network card and integrated AMD GPU graphics card require linux-firmware to be installed.

Accessibility

The BIOS setup is a simple, text-based interface, navigated with a keyboard. It does not expose many options apart from the standard time/date settings, and boot configuration.

To show a list of all available menus, press Esc.

To access the BIOS setup, press .

To access the boot menu, press .

Firmware

fwupd does not support this device.

Secure Boot

Secure Boot is untested, The device does not come with any Secure Boot keys installed from the factory, but there is an option in the BIOS to install HP factory keys.

Suspend-to-RAM

The firmware does not expose the necessary ACPI object () to support suspend-to-RAM, but it does have a similarly named object (), which is most likely patched at boot-time to enable this functionality (although there is no BIOS option to configure this). One can manually add support for suspend-to-RAM by doing the following:

First, get the iasl compiler by installing the package.

Then compile the following source using iasl <file>.asl:

And finally, tell the kernel to use the new ACPI table, and add the following option to the kernel command line to enable suspend-to-RAM: .

To check whether this worked, run the following command and confirm the deep memory sleep mode is selected:

Webcam

The webcam supports 720p, but this resolution is only available when not using the YUYV 4:2:2 video format (checked with OBS).

Function keys

By default, keys - perform their alternative functions, and is needed to press , but there is a BIOS option to change this behavior. The following table assumes this setting was disabled.

Key	Visible?¹	Marked?²	Effect
	Yes	Yes	`XF86XF86MonBrightnessDown`
	Yes	Yes	`XF86MonBrightnessUp`

The key is visible to and similar tools.
The physical key has a symbol on it, which describes its function.
systemd handles this by default, but does not consume it.

Additionally, Linux logs the following unknown key (what key combination triggers them is yet to be identified):

Kernel warnings

The kernel reports that the TSC timer is unstable:

[    2.611935] clocksource: timekeeping watchdog on CPU4: Marking clocksource 'tsc' as unstable because the skew is too large:
[    2.611947] clocksource:                       'hpet' wd_nsec: 504249213 wd_now: 22757d5 wd_last: 1b92cfa mask: ffffffff

[    2.611970] TSC found unstable after boot, most likely due to broken BIOS. Use 'tsc=unstable'.

The kernel also reports the following ACPI errors:

Despite these errors, the system is stable and operates correctly.
