Old method

• Reference: https://blog.frehi.be/2022/05/04/updating-hp-bios-firmware-from-linux/
• Get exact model of the system:

sudo dmidecode | grep "Product Name"    # or lshw

• Go to HP website, and download BIOS-System Firmware (file named like sp144565.exe).
• Unzip the file using 7zip

mkdir hp-bios
cd hp-bios
7z x ../sp144565.exe

• There are several *.bin files, for different models (see also History.txt):

ls *.bin
# T37_01120000.bin
# T39_01120000.bin
# T76_01120000.bin
sudo dmidecode | grep T76
#     Version: T76 Ver. 01.12.00

• Copy the file to EFI directory:

mkdir -p /boot/efi/EFI/HP/DEVFW
cp T76_01120000.bin /boot/efi/EFI/HP/DEVFW/firmware.bin

• Reboot the PC. In GRUB, select UEFI Firmware Settings. In HP menu, select Update System and Supported Device Firmware.
