Updated BIOS and now Windows isn't detecting TPM.

[zeth07]

I had outdated BIOS and the page I saw said F.60 / SP149071 for the HP Pavilion 590-p0xxx, ROM family 8433, and Windows 10 64-bit was the one to use so I did that and then Windows no longer detected TPM. But now when I tried to troubleshoot again through your virtual assistant it is listing the BIOS as HP Consumer Desktop PC BIOS Update (ROM Family SSID 8433)  F.41 Rev.A for the specific model I inputted.

So what is the deal with the discrepancy between my exact product and the F.60 family package instead? And what am I supposed to do to recover the missing TPM or fix my BIOS since when I tried to use an older one the "Update" part wouldn't let me since it obviously detected one as the older version. Is there a way to rollback BIOS?

I have an HP Pavilion Desktop 590-p0xxx with motherboard/ROM family 8433 and AMD Ryzen 5 2400G.

Before updating the BIOS, Windows detected the AMD firmware TPM (firmware version 3.16.0.4) and Get tpm reported tpm present=true.

After updating from BIOS F.08 to F.60 (SP149071), Windows reports tpmpresent=false. The BIOS still shows TPM Device: Available, TPM State: Enable, and Clean TPM: No. The AMD PSP device appears in Device Manager and reports working normally, it says AMD PSP 10.0 Device.

I have already performed a full power reset and restored BIOS defaults, with no improvement. The F.59 installer (SP146846) blocks the downgrade because it is older than the installed BIOS.

Please advise on a supported procedure to restore firmware TPM detection or safely recover the previous BIOS version for this exact system. I do not want to clear the TPM or force-flash an older BIOS without a verified procedure.

EDIT: 

I am experiencing a recurring Secure Boot firmware update failure on my HP Pavilion 590-p0044 desktop (product number 3LA79AA#ABA, motherboard/ROM family 8433).

Windows repeatedly logs these errors:

• Event ID 1801 — TPM-WMI: Reports that the Secure Boot certificate authorities/keys need to be updated.

• Event ID 1796 — TPM-WMI: Reports that the Secure Boot update failed to update a firmware variable with error 0x800700c1.

These errors occurred on my previous BIOS version F.08 and continue after updating to BIOS F.60. The latest events occurred on October 22, 2026, and the same errors have appeared repeatedly throughout October 21–22.

The Secure-Boot-Update scheduled task is enabled and reports a successful task result (0), even though Event 1796 continues to report firmware-update failures. Windows reports that Secure Boot is enabled.

I also have a separate issue in which Windows no longer detects the AMD firmware TPM after updating from BIOS F.08 to F.60. The BIOS shows TPM Device as Available and TPM State as Enable, but Windows reports TpmPresent = False.

I noticed that the BIOS support listing for my exact product appeared to list F.41, while the F.60 package was available for the broader Pavilion 590-p0xxx / ROM family 8433. I would like HP to confirm whether F.60 is supported for my exact product and serial number.

Please advise on the officially supported way to resolve the recurring Secure Boot update failure and restore TPM detection. I do not want to force a BIOS downgrade or make manual changes to Secure Boot keys without HP's guidance.

Greetings @zeth07 

Your PC faces two BIOS problems:

1. A TPM 2.0 version problem that can only be fixed with a future BIOS update.

2. A Secure Boot (PK) database problem also requiring a future BIOS update.

The 8-25-2023 F.60 BIOS update may be the last BIOS update available for your PC.

The 590 series PCs predate an entire group of HP AMD PCs placed into "Legacy" status. Legacy status means HP will not be providing future BIOS updates.

The list of HP PCs placed into Legacy status can be reviewed at this HP Site.

Your PC is not on the above list. But it's pretty safe to assume the older 590 series PCs will not be getting future BIOS updates to fix EFI firmware issues.

There is nothing, I am aware of, that can be done to update your PC's TPM version at this time.

You will not be able to play games requiring the latest TPM 2.0 version.

You might be able to temporarily workaround the Secure Boot problem by following the steps described in this HP Forum Link.

Before I go messing with that, can you explain why it previously had the TPM listed in windows and now it is saying it isn't there at all?

Is it because the BIOS update expects a higher TPM and it can't do that? If so shouldn't I somehow revert the BIOS so that I can at least get the previous TPM?

I'm not necessarily worried about playing games that need TPM 2.0, I am worried about the TPM saying it was there and now saying it isn't even though the BIOS clearly says it is there in the BIOS itself as available.

I don't know why the TPM is now missing in action after doing a BIOS update. A BIOS update typically resets the BIOS to factory default settings; TPM is on, Secure Boot is on, Legacy support is off.

The TPM and Secure Boot are two distinct security functions.

A permanent Secure Boot problem will adversely impact Windows security as time progresses.

A permanent TPM problem will adversely affect certain games and other Windows functions (BitLocker) requiring an active TPM.

Maybe a different Forum member can assist.
