Is there anybody who has successfully enabled the TPM on the XPS 13 9343 when using Windows 7?
I have 4 of these things. I installed Windows 7 x64 Enterprise on them from our MDT server after I imported the latest Windows 7 driver pack for this model. Now I'm finding that Windows is reporting that there is no available TPM chip.
I found like one thing on the internet about this, and it was for a different style of XPS 13. The guy was saying you can't use the TPM unless you are in UEFI mode with Secure Boot enabled. I've since tested and found out this isn't exactly true as I've installed Windows 8 without Secure Boot was able to initialize and change the password on the TPM. Take that same machine and put Windows 7 on it and the TPM doesn't show up anywhere in Device Manager, not even as an unknown device.
I called tech support and they tried to help, but it didn't go anywhere. They told me some of my machines didn't have a TPM chip and had supporting evidence that seemed to make sense at the time, but more testing disputes that. On the machines he told me have no TPM I installed Windows 8 and all of a sudden I have a TPM again. I installed Windows 7 on the machine he told me definitely has a TPM and Windows 7 didn't see it.
I updated the BIOS to the latest. I found the TPM listed in the BIOS. I couldn't find it when I was on the phone with tech support as I wasn't used to seeing it as Intel PTT. It's enabled.
I tried installing Windows 7 with no drivers injected to see if maybe a driver was getting installed for it and I just wasn't recognizing the name. Windows 7 still doesn't see a TPM. I installed Windows 8 with no drivers and Windows 8 does recognize the TPM and installs the Microsoft driver.
How do I get this TPM to work in Windows 7?
