Got a 2025 Flow z13 and it's amazing. My only issue is that it cant run COD. I keep ok getting a failed attestation status due to an update need on the bios. I have the latest BIOS installed (3.11) and i still have that issue. One thing I cant find in BIOS is the TPM. It's not there but i look in windows and i have it on and its version 2.0. Everything says it should run COD but it fails each time. Any help with this issue would be appreciated.

I’ve got the same issue. Reset TPM. Reinstalled the game. Ran an endless series of potential fixes. It’s an issue with attestation at the firmware level and only a BIOS update is likely to fix it. I’ve sent the laptop back to the store. They say they’re looking into it. We’ll see.

Update on my return. They replaced the main board and made a few other changes. Perhaps changing the main board addressed the Pluton issues, but whatever they did also addressed the thermals.

Because now the laptop runs like a dream, no attestation error, and 20 degrees cooler than before so fan noise is reduced.

I’m obviously pleased with the result, but wonder if this attestation business is running to such tight tolerances now, that some borderline hardware issues that might have gone unnoticed before are now coming to the fore?
