The PC cant boot from any device, even if I disable secure boot and enable legacy.
So I search for a bios update, currently it is A0.12 (11/10/2015), on the HP support homepage are no downloads
There should be a update file called sp144131.exe
But nowhere to find, does anyone has a copy?
Thanks

I finally solved it after hours togehter with the AI 🤓
SP85633 creates only this files:
ODEA020E.exe
ODEA020L.exe
Opening or extracting with parameters and tools wont work - but - it does not work because of Win11 protection mechanism. Compatibility mode fails also.
Then I tried it on another old W7 Notebook and then I got all the options, extract the BIOS-image or prepair USB stick.
I decided for the second option and then I went to the damaged PC:
1) Disconnect Power
2) Connect USB stick to the rear USB socket
3) Hold togehter the two keys "Windows" + "B" and keep holding
4) Connect Power Cable and turn PC on, keep holding the keys until PC beeps
5) Update starts - do nothing until finished
Thanks for the initial SP-File and your efforts

There is no such file number and even if there was, it would be for PCs that are at least 7 years newer than yours based on the HP Softpaq file number range.

The parts list for your PC indicates that it comes with a HP 'Odense' motherboard which has a SSID of 2B47.
Below are the info and exe file links to the last BIOS update HP released for your PC's motherboard (A0.20):

Thanks - it seems to be the right BIOS, but the installer is for windows only.
And I can´t start windows and I can´t start from any secure boot usb or legacy cdrom.
I also did not find a way to extract a bin-file from the Windows-Installer

You're very welcome.
Unfortunately, there isn't a way to extract the BIN file from the exe file other than to use another PC with W10 on it to create a bootable USB recovery drive.
But it is kind of tricky for how to do it with this file and also something doesn't make any sense to me.
You run the exe file and it will unpack to a SWSetup folder.
Inside that folder there will be a sp85633 folder and inside that folder there will be two files.
Now this is the part I don't understand.
I expected one file in there with the BIOS file labeled 2B47.
But both files are labeled differently than I expected and the only difference is one ends in an 'E' and the other in a 'L'
You can run either of these files and insert a USB flash drive of 20 MB or greater and after a moment, a screen will pop up to create a USB BIOS recovery drive.
The question is why are they labeled differently and which of the two files do you use, or doesn't it matter?
The info page for the file number indicates it is for 2B47, so I don't know what to say other than that would be the only way to try and recover/update the BIOS.
Here is an info link for the process:

Yes, that is unfortunatelly very tricky.
As I found on the net the difference of this two files may be one 32bit and the other 64bit, but none of them is extractable or creates a usb stick or rom image.
But - I found this with google ai (sorry for german) - but that loops to the beginning - the search for sp144131.exe:
⬇️⬇️⬇️
- Stecken Sie einen leeren USB-Stick (am besten im FAT32-Format) in den Zweit-PC.
- Starten Sie die Datei sp144131.exe auf dem Zweit-PC.
- Der HP-Assistent öffnet sich. Wählen Sie diesmal nicht „Update“, sondern die Option „Create Recovery USB Flash Drive“ (Wiederherstellungs-USB-Stick erstellen).
- Wählen Sie Ihren USB-Stick aus und lassen Sie das Tool die BIOS-Dateien auf den Stick schreiben.
(Hinweis aus der Community: Sollte sich das Fenster auf einem modernen Windows 11 PC nicht öffnen, führen Sie es auf einem älteren Windows 10/7 PC aus, dort klappt die grafische Oberfläche des alten Tools immer). [1]
- Schalten Sie den HP-PC komplett aus und trennen Sie ihn vom Strom.
- Stecken Sie den soeben erstellten BIOS-Wiederherstellungs-Stick in einen der hinteren Anschlüsse.
- Halten Sie auf der Tastatur die Tasten Windows-Taste + B gleichzeitig fest gedrückt.
- Stecken Sie den Strom ein und drücken Sie (während Sie Win + B weiterhin gedrückt halten) für ca. 2 bis 3 Sekunden den Einschaltknopf des PCs.
- Lassen Sie den Einschaltknopf los, aber halten Sie Win + B so lange gedrückt, bis der PC anfängt laut zu piepen oder der Bildschirm anspringt.

Anytime.
Glad to have been of assistance and good to know you were able to update the BIOS.
I knew the file didn't work on W10 which is why I suggested you create the recovery drive on W10-.
As I wrote before, it created a recovery drive on W10 for me with either of the two files.
However, it seems like W7 is a better option to create the USB recovery drive with.
I have no PC's left with W7 on them anymore and I would have had to remove W11 from one of my old PCs to reinstall W7 on, which I was not willing to do.
