Surface book 2 windows 116/25/2023 ![]() When recovery from flash drive completes, it clears TPM and the UEFI loop issue. I finally got Recovery to work when I used a different model of Kingston flash drive "DT Ultimate G2" rather then the "DT micro3.1" or Dell recovery/Silicon Power brand flash drive which I'd re-purposed for Win10 install. I'm sure that had I called MS for out-of-warranty support, they would not know how to fix this and would have offered the $600 mail in to repair/replace, at best. I couldn't disable TPM and got the same error when trying to change secure boot mode to none :( It's very weird that it will boot to the Eraser tool flash drive. It looped on this "failed to change" screen. The Surface Data eraser tool worked to clean the disk but I still couldn't get the device to boot to a Recovery flash drive. This happened to me after trying Linux Lite on my surface book SV7-00001 completely replacing Windows OS, not a dual boot, and then deciding to go back to Windows OS. Now it's also no longer possible to launch Bitlocker ("This device can´t use a Trusted Platform Module."). Eventually, I disabled Bitlocker so I wouldn't have to deal with the blue window anymore. This allowed me to access Windows, but it continued to show up every time I restarted my laptop. When I turned on my Surface Book 2 a few weeks ago, I was greeted with a Bitlocker screen prompting me to enter a recovery key. So the TPM is no longer accessible for me.ĭo you think it could be a hadware defect? ![]() On the contrary, now it doesn't even show up in the device manager under security devices. Please reboot the system to try again".Įven after a clean installation of Windows (older version) via USB stick, I was still not able to activate the TPM. Every time I get the error message: "TPM failure - The system failed to change the state of the TPM. ![]() So I tried to activate it via the UEFI BIOS, but without success. While trying to upgrade my SB2 to Windows 11, I noticed that my TPM 2.0 is not enabled.
