Can't enable TPM and Secure Boot simultaneously.

[Gabozz11]

Hi all!

I was trying to prepare my laptop for Windows 11 (even tough my CPU won't be supported officially), and at first the PC Health Check app said my PC won't be able to run it.
I checked if I have TPM enabled, and it was, so naturally I checked Secure Boot, which was turned off.
I turned it on, and now I don't have TPM enabled, the TPM Manager Tool says it "cannot load management console", with an error code 0x90080029. If i turn off Secure Boot, then TPM is still unavailable with the same error code.

 

If I reset the BIOS, TPM works again, and Secure Boot is turned off. (Though whynotwin11 states SB is supported, it is turned off)

 

Now the unfortunate problem is that I don't have any kind of settings in the BIOS to set TPM on or off.

Can you guys think of any kind of answer or troubleshoot for it? It would be appreciated a lot!

Laptop info:

 

Model: Asus GL502VT
BIOS version is 3.0.3 up to date as of 2019/06

 

If you need any more information hit me up! And thanks in advance!

P.S.: I won't install Windows 11 before it comes out later this year/early 2022, as this is my only PC for work and gaming, but I wan't to be prepared.

its possible that you get a bios update soon that can fix this issue. you said this bios is from 2019 so its at least a year old. if asus is planning on continuing support for it, and if this is a bug, its possible it will get fixed soon so your mobo is compatible.

WNW11 says that Secure Boot is okay as you only need a Secure Boot Capable system. It does NOT need to be enabled! Regardless, I would update your BIOS as it should support both being on.
