BIOS v90 1.7.0 not installing (UEFI issue) on Dragonfly G4

[OhOkay070]

The company I work for has a fleet of HP dragonfly g4's which are having issues connecting to screens via USB-C - long story short, we have identified that upgrading to the latest BIOS version (most of the fleet is currently on v90 1.5.5 or 1.6.3) fixes this issue. The only way we have successfully upgraded some test devices to v90 1.7.0 is manually - however, when we try and update the BIOS on test devices, the BIOS only installs successfully around 10% of the time. 

The issue is that when the BIOS updates, it displays in Device Manager as driver version 1.7.0 but comes up with an error icon against the HP V90 System Firmware display name and just defaults to the previous version firmware (either 1.6.3 or 1.5.5). 

Also, it's not going to be possible to install this manually for our entire fleet of G4s. We would normally use Intune autopatch to roll this out (and it has come up as an applicable update in Intune) however when it is rolled out via autopatch the BIOS update fails to install correctly in the same way when installed manually. Same deal when we try and package the update as an application in Intune and push out that way.

I initially thought that it was an Intune issue, however Microsoft came back and said that it is a UEFI error. 

Has anyone else had these issues installing v90 1.7.0.0?

Like you our company has a fleet of dragonfly g4's. 

We've not had any issues with USB-C connections to screens  but we have had 4 instances in the last 10 days where the windows update install of the 1.7.0 v90 bios firmware has not completed correctly and corrupt the BCD file. this leaves the device unable to boot windows.

the fix I've used to resolve is here https://www.youtube.com/watch?v=63nCXKxe9aw 

After getting back into windows, device manager v90 firmware shows the alert error and says the firmware is not installed correctly.

However on running a manual install of SP155927 from here https://support.hp.com/gb-en/drivers/swdetails/hp-dragonfly-13.5-inch-g4-notebook-pc/2101595419/swIt... its installs fine on the same devices and I've had no further issues. 

We've not attempted an automated deployment of sp155927 via Intune yet but I do now have control of the driver updates for subsequent HP firmware and BIOS updates via Windows update for business in Intune.

Incidentally have you had any issues with the G4 camera failing in teams / zoom calls or WHFB sign in's?

Luckily we haven't seen any corruptions of BIOS install - it fails at the first step of the BIOS installing and just drops the user back into log in screen. Thanks for the yt link though - if it does happen to us that will  be handy. 

We have been using that SP155927 install you mention below - that's the package that won't silently install (and doesn't deploy correctly via Intune), and only sometimes installs correctly for us when run manually. 

We haven't had any issues with cameras failing - either in teams/zoom calls or when doing WHfB. 

This tool might help ID the camera issue: https://ftp.ext.hp.com/pub/caps-softpaq/cmit/HPIA.html

I saw there is a new version  of v90 on HP site today 01.08.00 Rev.A https://ftp.hp.com/pub/softpaq/sp156501-157000/sp156777.exe

Hopefully this helps

Awesome - thanks for that link.

We are seeing issues on HP ProBooks latest BIOS where USB-C STOPS charging until the monitors power is reset then it'll work for a bit until the monitor needs resetting again

Hi,

I had a similar problem. In the Device Manager, near the BIOS firmware, there was an icon that the firmware was not installed. There were also problems with the camera. It periodically turned off during calls (Zoom, Skype...). In the end, it turned off completely (also after restrating notebook).
I used the link to update the BIOS to 01.08.00 and now the camera works.
However, in the Device Manager, there is still the same error near the BIOS firmware.

Thank you for advice.

what I'm seeing on my HP Dragonfly G4's running 24H2 and 23H2 is that windows device manager does not correctly display the BIOS version installed.

My device for example the device manager shows HPv90 System Firmware 1.7.0.0 dated 14/11/2024. It doesn't have an alert flag. 

However on running "msinfo32" System Information from within windows it shows its running v90  01.80.00 dated 8th Jan 2025 and this is confirmed by running into the BIOS set-up Basic System information which shows 1.8 as well.
