BIOS upgrade

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.
