HP Recommended

Hello,

we need to update the secure boot certificates on our HP ProDesk 400 G5 Microtower PCs but there seems to be no BIOS update available for these machines (allthough we bought them in 2019).

 

According to

https://support.hp.com/us-en/document/ish_13070353-13070429-16

 

there is a way to manually upgrade the certificates if there is no BIOS update available:

For HP Commercial PCs that do not receive a BIOS update because they have reached their End of Service Life (EOSL) date (including select 2018 products and all HP PCs released 2017 and earlier), HP has developed a solution to allow you to update your system manually.

 

Could you please provide us with a description on how to update our system manually?

 

Thank you and best regards,

Toni
