SER8 Windows 10 does not detect TPM

jjsk

I have TPM enabled in the BIOS but it’s not detected by Windows.
I searched the forum and internet and do not see a solution that would work.
(even some missing resistors, but for a different beelink model)

what can be a fix for this issue?

I confirm, Windows 10 does not detect TPM, Windows 11 does, with the same BIOS settings.
Test it.

Hi there
Thanks for sharing , appreciated.!

It’s windows 10 which I need to migrate to 11. but it does not pass the readiness check because 10 does not seem to recognize Pluton based TPM 2.0. I have installed the latest chipset drivers .

device manager in win10:

the tpm driver is there as well but hidden (here is a pic with "Show hidden devices)

Hi, there
Please install Windows 11
Windows11 tutorial: https://url.bee-link.cn/74zu，
Windows 10 might not detect TPM

I guess whoever suggested a fresh win11 install did not see that i need to migrate the existing Win 10 system. a clean Win 11 install, would have wiped out all my data and applications. I did not want to go through this.

So I finally figured it out. Go to BIOS and disable the Pluton processor. Enable ASP fTPM under SOC options. (the default settings are auto - not compatible with Win10 for the in place upgrade).

After this the TPM 2.0 device shows up in the Device Manager and The Win11 upgrade check passes.

After the migration I can re-enable Pluton for whatever advanced functionality it offers.

Hi,
I have activated ASP fTPM and deactivated Pluton but Windows still shows no TPM. Is there anything else to do?

Hi,
I got it working! After enabling the ASP fTPM, simply restarting the PC doesn’t seem to be enough. After shutting down the PC yesterday and restarting it today, I discovered that the Trusted Computing setting in the BIOS was disabled. I suspect switching the TPMs disabled the feature, but I only noticed that today. I re-enabled Trusted Computing, and after another reboot, my Windows 10 now showed a TPM, and I was finally able to upgrade to Windows 11.

Afterward, I re-enabled MS Pluton, and now everything works perfectly.
