Upgrade BIOS

[Gilberto3]

Hi all. I have a question: from HP Assistant I received indication about BIOS upgrading to a new version, F28. Present one is F22. When I try to update it, the procedure is closed correctly, without any alarm message, but after the required restart the BIOS is always displayed in release F22. I tried several times, always with the same result. I also tried to update it with earlier version, as well as F23 for instance, with the same result: it remains in F22. My laptop is a "Notebook HP - 15-ac085nl (ENERGY STAR)", featured by Windows 10 (64-bit) version 1809 and build 17763.253, serial number [edited] and product number N6A21EA#ABZ. Can anyone support me about the issue? Regards, Gilberto.

Hi KrazyToad. Thanks for your help. I downloaded the F.27 Rev.A BIOS from HP server as well as suggested, without any result. The situation is the same described in my original post. Thank you anyway for the support. The BIOS remained in F.22 as well as before. I tried in the past with F.23, F.27 and F.28 BIOS (last one shown by HP Support Assistant application, but on the HP server is not displayd yet). Nothing has changed. I do not know is it could depend on UEFI BIOS Modality. I attach here a "photo" of my System Information window. Anyway, thanks again. Regards.
