please HELP...this is a very similar issue to: How to perform a HP BIOS upgrade with only Ubuntu?

I've tried it all above, and can't seem to boot from exe. since my HP PC hardware Diagnositics UEFI doesn't give me the update option.The current version of BIOS is F.12... and the newest is from 2017 is F.20 for my product number. https://support.hp.com/us-en/drivers/selfservice/hp-pavilion-15-n000-notebook-pc-series/5401225/model/6453751

All I have on my laptop is Ubuntu, I recently upgraded to 20.04 from 18.04 .First I was missing a lot of RAM, I fixed that from 1.4GB to 5GB by switching places of my hardware RAM.guess that's a hardware malfunction. I'm much more happy with the speed and appreciate Ubuntu 20.04 all ready.I wish to keep it.

the reason I'd like to update BIOS is I can't seem to have any options select-able apart from time, date and system log. the rest is grey. any way I hope to fix a few issues regarding my Wireless adapter, the Wifi works, but occasionally just stops, so I turn it of and turn back on to connect again. but the Bluetooth says missing dongle, I recognize that the adapter for WLan and Bluetooth are the same adapter. and my dual graphics doesn't seem to be working.

all in all, i hope that update BIOS would fix this problem, and can't seem to boot the support packs in exe. . I'm considering booting free dos, and then installing the updates (btw would i need to install F.14 ,F.15,ect. or just the newest F.20 - i also see on hp support that the F.13 is missing.)?

Do i maybe have to update the hardware diagnostic UEFI, and how?

I'm new to the community, be gentle, I come in peace. I have some knowledge of I.T. but as you've probably noticed not that much. any help would do. I just need this as it is the only form of working from home I have right now. take care.

I just upgraded the BIOS on a HP 340s, which runs Ubuntu 20.04. I wasn't able to locate any "update BIOS" menus whatsoever, and didn't want to experiment with copying files manually to the EFI partition either. It seems that the BIOS .exe for that particular machine is packed in a way that can't be easily extracted under Linux, so sadly, I needed a windows machine. Below are the steps that should do the trick:

  • If you can get your hands on a Windows machine, prepare a USB boot drive with the BIOS installer .exe (I think it was the second option, install on a USB drive or similar).
  • Plug in the USB drive and restart the notebook to be updated. Hold ESC to bring up the system information/setup etc. options, then choose F9 (boot devices), then "boot from an EFI file".
  • You should be able to see the USB drive you created under Windows, named "Hp Tools" or something similar.
  • Go to the Hewlett-Packard/BIOSUpdate directory and choose the HpBiosUpdate.efi file.
  • The next screen will warn you to switch to AC power and will proceed with the BIOS update.

This did the trick for me. The USB drive was FAT32 formatted and I don't think that the BIOS (pre-?)installer did something special to it under Windows.
