EliteDesk 800 G2 DM - BIOS Updates vanished

[turntable]

On checking the product page for updates we found that the system BIOS we downloaded last year from the website and are using on a few hundred devices has vanished.

Strangely not only that release but also the previous 9 releases vanished form the product page.

Does anybody can shed some light on this.

Following the versions missing from the product page, which are listed in the revision history which came with the BIOS update SP we are currently using:

Version 2.47
Version 2.45
Version 2.44
Version 2.43
Version 2.42
Version 2.39
Version 2.37
Version 2.36
Version 2.35

The current version on the product page is 2.35

[TheOldMan]

Interesting.  I looked at the support page for the BIOS on the EliteDesk 800 G2 tower and SFF which have previous versions listed.  Not exactly as listed in your post but many more versions.

https://support.hp.com/us-en/drivers/selfservice/hp-elitedesk-800-g2-tower-pc/7633297

When the current BIOS version is clicked on (version 2.51), there is a "Previous version" tab beneath the "Associated files" tab.  Click on that and many previous versions will show up.

I see you are from Germany, so I do not know if what we see in the USA is different than in your area/region, but the link I posted is USA origin.

Hello TheOldMan.

THX a lot for you answer.

I have to apologize in being imprecise with my inital post.

We have the problem described with the Desktop-Mini variant.

Indeed the tower page shows newer BIOS versions but these are not compatible with the DM.

Have a look here for the DM version Link 

[TheOldMan]

Yes, the Mini has different BIOS and it seems that 2.35 is the latest.

You might want to check with the Business Class support.

Hi TheOldMan.

Thanks again for trying to help.

I tried to contact HP support but I gave up.

Strangely they even do not seem to be able to understand the problem or being of any help.

"The BIOS update on the website is outdated and the latest 9 versions have vanished".

Not to hard to understand I think.

Cheers.

And just for the record I post the revision history of the BIOS where it is quite easy to see that the version on the website is very very very very old.

Strange indeed.

Probably an error but who knows.  It would have been nice if the Business Center support was able to answer what/why they are missing when you have some documentation showing there used to be updates.

I suspect the files are still on the FTP server, I just do not know how to find them or even where the index files are located.

[letifosiferrari]

I noticed the same thing indeed. About a month and a half ago the web site did have the BIOS version 02.52, but as mentioned above it disappeared and I am only seeing 02.35.

If you install the HP assistant on the HP computer, it should still be showing the latest 02.52 BIOS update as being available (at least it is in my case), with the file name sp111858.

I did download the file sp111858.exe at the time it was available on the web site, but given that it is not shown on the web site anymore, I am unsure if I will apply this update in case it got pulled for a valid reason (even though it does look like a site issue given that the HP assistant software still shows it).

Side note: I did report this issue via the feedback form on the HP support web site about three weeks ago.

Hi Tifosi 👍.

Thanks for posting the SP number of the latest version, and also the information that it is still available via HP assistant. So it should be possible to download the SP via HP FTP-Server.

I opened a HP support case via telephone, and they have now escalated it to 2nd level. Registering an HP business support account failed due to bugs on their website. I remember the days where HP support was much more superior.

[turntable]

Today I received the information from second level support, that the product is no longer being supported.

Come on HP this is so embarrassing.

What has happened to your company which was a paragon in computer industry long time ago?
