HP Firmware update via Windows Update on HP ZBook Firefly not installing

[MarkG2506]

Hello, 

I'm the IT support manager for our company. We have a mix of HP laptops and most of them update fine via Windows Update, even the firmware updates that HP now rolls out via Windows Update.

However we also have 30 ZBook Firefly 14 G7 laptops. Specifically on these devices the HP Firmware updates aren't installed automatically. Users see a message popping up on the taskbar saying they need to reboot in order to apply the HP Firmware update, for instance the HP S73 System Firmware, but when they restart, they see a text 'A system update is being installed' (roughly translated from Dutch) for about two seconds after the restart, after which the laptop boots into Windows, but the Firmware update isn't installed. 

After a couple of days or so, another message asking the user to restart to apply the same S73 Firmware update appears, but again the restart doesn't apply the update. 

We have installed the HP Client Management Script Library, which allow us to disable the BIOS function 'Prompt for Admin authentication on Capsule Module'. This prevents the BIOS password prompt on applying an update. Still, to no avail, the update isn't applied. In Device manager the System Firmware has a yellow warning indicating the update isn't installed.

Has anyone come against this issue and does anybody know how to resolve this? Thank you in advance.

Best regards,

Mark

I am not sure if it's ESP(EFI System Partition) size problem.

You can check how large size remaining on your ESP?

1. Open command prompt with admin

2. Type in command : mountvol z: /s

3. Change Partition to Z: 

4. Use command Dir to check size

Hi RobinChen,

Thank you so much for your reply. I have checked the volume, and it's quite small, only 25 MB. According to the information I found here:  https://support.hp.com/au-en/document/c06466416 this does appear to be too small. HP says the volume should be at least 260 MB. So, this could be the cause of the problem. 

What would be the best way to enlarge this partition?

I tried DiskPart, DiskMgr, Powershell but all cannot adjusted size of ESP.

3rd party tool EaseUS can achieve it but need by Pro license. 

There is other way on Linux can achieve it but I didn't try on it since I am not Linux expert. Sorry :'(
