Windows 10: TPM Console Error 0x8007007A

I am facing the following error after replacing the motherboard in my laptop, when i run `tpm.msc`:


Loading of the management console failed. The data area passed to a system call is too small. Exception from HRESULT: 0x8007007A Try again.


I am running Windows 10 Pro 1909 on Dell M6400 ~11 years old legacy laptop.

The issue seem to be equal to this one.

The replacement Motherboard originally had some older bios version. Now I've updated BIOS to A13 latest available and tried to clear the TPM once again. Nothing changed.


The official troubleshooting guide only offers to "reinstall Windows" in this case. I've postedthis issue, asking to improve/justify this statement.

But that thread is hardly a good place for discussing possible workarounds for the issue I have.


Any other ideas?

Hi,



Thank you for writing to Microsoft Community Forums.



This could be the issue when the firmware is not upto date, you can try the troubleshooting steps provided below to further narrow down to the root cause of the issue.



Method 1: TPM console troubleshoot.



I suggest you to try the troubleshooting method provided by dell on

"Cannot load management console" opening TPM Management console in Windows 10 Version 1703 and check if this helps you.





Method 2: Update BIOS and firmware.



I suggest you to contact the
manufacturer and update all the compatible firmware drivers for Windows 10.



Disclaimer: Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft
cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.



Make the above changes and check if this helps you, if you still face the issue, reply to this post with more information.



Hope it helps,
