Windows 10: "Firmware TPM - Enables PTT in SkuMgr. Discrete TPM - Disables PTT in SkuMgr. Warning!...

Hello,I have been having trouble with upgrading to Win11. It says that I don't have TPM 2.0 enabled and I have to enable it from my BIOS.I have a few questions:1. If my TPM device selection settings at Advanced -> PCH-FW Configuration have always been on "Discrete TPM", will changing it to "Firmware TPM" actually change anything?2. What is BitLocker? I keep seeing it mentioned in the TPM discussions and I don't know if I have it enabled or not, how can I know if I am using BitLocker? If my TPM had been disabled all this time does that mean I couldn't even use BitLocker at all?3. What is S

Reset TPM failed, resulting in slow login (have PTT not TPM)

I have a Lenovo Ideapad 710s. It has Intel PTT (Platform Trust Technology) rather than a dedicated TPM chip.

I got a Windows security center alert telling me that I needed to reset my security processor (clear TPM), so I did, clicking the "clear and restart" button. My computer rebooted, but I didn't get any prompt about clearing the TPM, and when I got to the
Windows 10 cover screen and clicked to get to the login screen, it took about 2 minutes for the login boxes to appear. It now does this every time I reset the computer. Further, the TPM security alert is still there, so the reset failed.

I have checked my bios and it's the latest version. I went into the bios to double-check that I don't have TPM, and the only related security option is one to turn PTT on or off. And when I go to tpm.msc, it verifies that this computer doesn't have TPM.

I don't really care about whether my PTT/TPM gets cleared, I just want my login screen to stop taking so long to appear. Please help!

Thanks,

Sarah

 

TPM support

The TPM 2.0 specifications can be implemented by a hardware chip, in which case it will be listed in the bios as 'TPM'. Newer processors can also support a firmware implementation of TPM 2.0. This is where it gets confusing as that may be listed in the bios as fTPM or PTT. All implementations of TPM 2.0, hardware or firmware, will meet the W11 requirements.

TPM 2.0 for Windows 11 - What about Intel PTT and AMD fTPM?

 

TPM update

Don't know if this is the right place for this thread but whatever, laptop informed me that " a firmware update is needed for you security processor (TPM)," now, i looked up what to do and from a microsoft support thing, the last step says to clear the tpm. it has a warning saying to back up my data, i would like to know what clearing the tpm does, and what measures i need to take to make sure nothing goes wrong.
