Installation

Note: Make sure you have the latest HP UEFI firmware installed.

Even if UEFI, Arch Linux and (e.g.) GRUB are correctly configured and with the correct UEFI NVRAM variables set, the system will not boot from the HDD/SSD. The problem is that HP hard coded the paths for the OS boot manager in their UEFI boot manager to \EFI\Microsoft\Boot\bootmgfw.efi to boot Microsoft Windows, regardless of how the UEFI NVRAM variables are changed. There are two workarounds:

Using the "Customized Boot" path option (recommended)

The latest HP firmware allows defining a “Customized Boot” path in the UEFI pre-boot graphical environment. Select the “Customized Boot” option in the UEFI pre-boot graphical environment under “Boot Options” and set the path to your OS boot loader on the EFI system partition e.g.:

\EFI\grub\grubx64.efi

Always verify the correct path to the .efi file. Also, adjust the device boot order (also in the UEFI pre-boot graphical environment) to boot this entry first.

Change the OS boot loader path to match the hard coded path

This article or section is being considered for removal.

Warning: This method is not recommended, as it will create conflicts in a dual boot setup with Microsoft Windows. Also, everytime you install GRUB, you have to remember to copy it to the hard coded path.

Change the UEFI application path of the OS boot loader to that hard coded path. On your EFI system partition; e.g. with esp being the EFI system partition mountpoint: 

# mkdir -p esp/EFI/Microsoft/Boot
# cp esp/EFI/grub/grubx64.efi esp/EFI/Microsoft/Boot/bootmgfw.efi

or 

# mkdir -p esp/EFI/BOOT
# cp esp/EFI/grub/grubx64.efi esp/EFI/BOOT/BOOTx64.EFI

Firmware

This notebook supports HDD FDE (SED). The HDD/SSD can be locked by setting a password in the UEFI pre-boot graphical environment under the option "DriveLock" (this requires setting a password for the UEFI pre-boot graphical environment first). If you replace the HDD/SSD, make sure to get a compatible one to make use of this feature.

Bluetooth

The default driver seems to work but cannot discover other devices. You need to either:

  1. Download the BCM20702A1-0a5c-21fb.hcd file from broadcom-bt-firmware and place it to the /lib/firmware/brcm directory. This is preferred.
  2. Use broadcom-bt-firmware-gitAUR but you will need to figure out conflicts with already installed firmware - beware that Bluetooth and WLAN are the on the same chip and you might easily break your existing setup.

Card reader

Use rts5227-dkmsAUR.

Function keys

The function key controlling the microphone does not work.

Power management

Resume on lid open feature needs to be enabled in the bios / uefi setup: Advanced > Built-in device options > Wake unit from sleep when lid is opened.
