HP Z420 Base Model Workstation - Seeking for a fix on Boot Secure Certificate

[Horatius]

Hi Guys,
I need some help here as my HP Z420 Base Model Workstation recently was prompted that it failed to perform a Microsoft Windows Update on Boot Secure Certificate.  I have noticed a slow boot up of my desktop and there are times when the desktop trying to recover from the "Sleep" mode, it was not able to recover quickly or successfully. I have tried to look for a HP BIOS update, but I noticed that the update there is not the latest version.  Nevertheless, I too downloaded it and installed it but it does not help to resolve the Boot Secure Certificate issue. 

Can anybody out there help me to get a fix on how to resolve this Boot Secure Certificate issue for my desktop (HP Z420 Base Model Workstation).  Thank you.

Hi @Horatius,

Welcome to the HP Support Community.
 

Thank you for providing the details of your HP Z420 Base Model Workstation.
 

The message you're seeing regarding the Microsoft Secure Boot Certificate is related to Microsoft's Secure Boot certificate update. HP has released BIOS updates for select commercial platforms to support this update.
 

For reference, please see the HP document below: HP Business PCs - Prepare for new Windows Secure Boot certificates | HP® Support
 

After reviewing your model, the HP Z420 Workstation is not included in the list of supported platforms for this Secure Boot certificate update. Additionally, the Z420 is an obsolete/end-of-support product, and there are no newer BIOS updates or firmware fixes available beyond those already published for this model.
 

Since you've already updated the BIOS to the latest version available for the Z420, there are no additional HP BIOS updates that can be applied to address this specific Secure Boot certificate notification.
 

Regarding the slow boot and resume from Sleep, these symptoms are not necessarily caused by the Secure Boot certificate message and may instead be related to Windows, storage health, drivers, or the age of the hardware.
 

If the Secure Boot certificate update is a requirement for your environment, you may need to consider migrating to a newer HP platform that is listed in the HP support document above.
 

I hope this clarifies the situation. Please let us know if you have any additional questions regarding your Z420, and we'll be happy to assist where HP support is available.
