Chosen Solution

I bought an XPS 13 9370 notebook with a CPU model of i7 8650u. I want to upgrade to windows11 system, but I am prompted that the TPM module is not found. Can I install a TPM module to solve this problem by myself? Thank you！

Sadly, with the ones which were originally shipped as “PRC” systems new have it completely removed, with a completely different motherboard. It cannot be added to the machines at all - even after purchase. The BIOS doesn’t support it and the motherboards are COMPLETELY UNIQUE to China (different DP/N and likely BIOS/Intel Boot Guard private keys), so you can’t swap them “like for like” outside of China, if it originated there.This list is not all inclusive, but it can be used as a baseline; if the model is related and lacks the TPM option, it might be another one with the TPM removed due to being destined to be sold as a “PRC” unit new. The rub about the “regulatory removal” Dells where they didn’t put a “TCM” module in is the laptop is 99% there but due to regulatory issues, the TPM had to be removed. This is not your fault, but sadly it means there is no official support from Microsoft! Yours checks all the boxes so it’ll run fine… but because yours lacks a HW TPM or fTPM, it will not be officially supported but it’s perfectly capable otherwise. The issue at play is a rather infamous “national security” law around TPMs which means non-homegrown TCM modules are banned, which rules out anything that isn’t from China as the TCM spec is a secret standard because (backdoored and almost certainly based on reversible encryption, which is frowned upon anywere else). NO NON-CHINA SPECIFIC MANUFACTURER TOUCHES THE “TCM” SPEC, or they have a Chinese subsidiary which is owned but keep a distance from the spec to avoid issues with literally any normal government.What Dell did was rather than deal with China’s “national security” TPM ban, Dell opted to remove the TPM on some of these systems until they could put a “TCM compliant” (known as a China TPM on spec sheets) or make the fTPM TCM compliant. As a result, a lot of these “PRC” laptops I can buy one bound for the US/Canada/any sane country has it, and yours lost it due to their regulatory nonsense around the matter. Now it’s possible it still has the fTPM, but they permanently disable it in the China BIOS, or use a China SKU part from Intel and sign the China BIOS with a different private key. For full support, you need a US motherboard you can program your ST onto to add the TPM back. The other options are the unofficial upgrade/whole unit replacement. If you replace the laptop and sell this one, its “PRC” origin gives it a permanent asterisk over this missing TPM. Warn the buyer so they know in advance! This is what you will see on a TCG complaint computer – Dell uses Infineon or Nuvoton (my 7490 is Nuvoton, while my E7440 was Infineon 1.2; fTPM computers will say AMD or Intel):

@eliauk take a good read on here and follow those instructions. See if your computer can run it. More instructions from Dell for the TPM are available right here
