Instructions to Update the BIOS/UEFI for an HP Laptop on Linux

To update the BIOS/UEFI firmware requires HP-specific files in the EFI System Partition, also referred to as ESP.

On a Linux system, the ESP is typically mounted on /boot/efi or /efi. Whithin you should also find a EFI directory, e.g. /boot/efi/EFI or /efi/EFI. This article assumes that the ESP is mounted on /efi and that the /efi/EFI directory exists. You can replace that with the mount point your system uses.

The HP-specific files are located in /efi/EFI/HP or /efi/EFI/Hewlet-Packard. These files typically come preinstalled in HP Windows PCs. If you have these files you could skip Install HP-specific files.

Swap Pause and Delete Keys for HP Omen 15 2020

This is an xkb_symbols option to swap the Pause and Delete keys for the HP Omen 15 2020 keyboard.

Following the instructions here https://unix.stackexchange.com/questions/212573/how-can-i-make-backspace-act-as-escape-using-setxkbmap/215062#215062 I was able to create a new symbol pause (see pause file in this gist), and add it to the evdev and evdev.lst files and then with the following command perform the remap:

setxkbmap -option pause:swapdelete

Technical information

Read manufacturer manual: http://h10032.www1.hp.com/ctg/Manual/c05819688 (archived link).

Tweaks

Monitor and improve power-saving, and increase battery life

Install PowerTOP (https://01.org/powertop/) and TLP (https://linrunner.de/en/tlp/tlp.html) tools.

sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install powertop tlp tlp-rdw

We install certutil and pk12util if necessary:

sudo apt install libnss3-tools

On Linux, Chromium uses the NSS Shared DB. Check if you have the ~/.pki/nssdb directory:

ls $HOME/.pki/nssdb

Reset root/admin password

Lost the root/admin password? You can reset it using the command-line. Recipe adapted from gitlab issue #308.

# start the console
sudo gitlab-rails console

This gist lets you keep IPython notebooks in git repositories. It tells git to ignore prompt numbers and program outputs when checking that a file has changed.

To use the script, follow the instructions given in the script's docstring.

For further details, read this blogpost.

The procedure outlined here is inspired by this answer on Stack Overflow.

	import ssl
	import socket

	# This script simply replays one side of an intercepted conversation between two Xiaomi
	# RB01 (International) AX3200 routers negotiating meshing.
	# In effect the script poses as a mesh slave, which causes the mesh master to enable netmode4.
	# Enabling netmode is needed as one step in unlocking the router and flashing OpenWrt.
	# The router should already have been taken through basic set-up before running this script.
	# Netmode4 can be confirmed with curl by requesting the following URL, where ${token} is the "stok"
	# variable from your admin session:

	//Override in your touch-enabled view (this can be differen than the view you use for displaying the cam preview)
	@Override
	public boolean onTouch(View view, MotionEvent motionEvent) {
	final int actionMasked = motionEvent.getActionMasked();
	if (actionMasked != MotionEvent.ACTION_DOWN) {
	return false;
	}
	if (mManualFocusEngaged) {
	Log.d(TAG, "Manual focus already engaged");
	return true;

	Sometimes after a hard reboot (power cut), if your synology cannot be logged in with DSM and it shows "System is getting ready. Please log in later" , please do these steps :

	#Admin login via ssh
	> synobootseq --set-boot-done
	> synobootseq --is-ready
	#optional
	> /usr/syno/etc/rc.d/S97apache-sys.sh start
	> /usr/syno/etc/rc.d/S95sshd.sh start
