The HP 15s-eq1124nw is a laptop featuring a 15.6" FHD IPS display, 16GB of RAM (2x8GB, 2666MHz), 512GB NVMe SSD, and a AMD Ryzen 5 4500U with integrated graphics.
Installation
The Realtek RTL8822CE network card and integrated AMD GPU graphics card require
linux-firmware
to be installed.
Accessibility
The UEFI 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 UEFI setup, press
F10
.
To access the boot menu, press
F9
.
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 UEFI to install HP factory keys.
Suspend-to-RAM
See
Power management/Suspend and hibernate#Changing suspend method
for the general context in which this workaround applies.
The firmware does not expose the necessary ACPI object (
\_S3
) to support suspend-to-RAM, but it does have a similarly named object (
\XS3
), which is most likely patched at boot-time to enable this functionality (although there is no UEFI 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
acpica
package.
Then compile the following source using
iasl <file>.asl
:
DefinitionBlock ("ssdt.aml", "SSDT", 1, "HACK  ", "S3      ", 0x00000001)
{
	Scope (\)
	{
		Name (_S3, Package (0x04)
		{
			0x03,
			Zero,
			Zero,
			Zero
		})
	}
}
And finally,
tell the kernel to use the new ACPI table
.
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
F1
-
F12
perform their alternative functions, and
Fn+F
x
is needed to press
F
x
, but there is a UEFI option to change this behavior. The following table assumes this setting was disabled.

The key is visible to
xev
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):
[11654.430121] atkbd serio0: Unknown key pressed (translated set 2, code 0xab on isa0060/serio0).
[11654.430130] atkbd serio0: Use 'setkeycodes e02b <keycode>' to make it known.
[11654.555213] atkbd serio0: Unknown key released (translated set 2, code 0xab on isa0060/serio0).
[11654.555224] atkbd serio0: Use 'setkeycodes e02b <keycode>' to make it known.
Kernel warnings
The kernel reports that the TSC timer is unstable:

The kernel also reports the following ACPI errors:
