Hi!
I just bought a ser8 8745 from Amazon.de. Everything worked fine, except the Windows installation seemed kind of broken as it did no updates.
I decided to upgrade the memory. I bought the exact same as you had on (Crucial), only 96GB.

Then the Windows installation stopped working right (problem with Graphics). I installed a copy of windows 10 that I already had on a USB stick. I then installed the graphics driver and it works excellent.

However, when I tried to update to Windows 11, it cannot detect the TPM 2.0.

I checked the Bios, and it’s all enabled and correct.

However the TPM device is not even visible in the Devise Manager.

What can be done?
