HP Recommended
Product: OMEN by HP 875-1000 Obelisk Desktop PC (5MG70AV)
Operating System: Microsoft Windows 11

I'm having a TPM/Secure Boot attestation problem with Fortnite/Easy Anti-Cheat.

The error says: “TPM attestation failed: unable to verify secure boot. event missing from measured bootlog.”

I have already updated my HP BIOS and confirmed that TPM 2.0 is ready for use, Secure Boot is enabled, and Windows is running in UEFI mode.

Windows Measured Boot is reporting that Secure Boot is enabled on the computer but is not being recorded correctly in the TCG measured-boot log. Windows Event Viewer also shows repeated Kernel-Boot Event ID 292 errors saying: “Failed to update the SBAT value in FW.”

I’m looking for help determining whether this is an HP firmware/Secure Boot/SBAT issue and whether there is a recommended firmware fix.
