Not sure where this post fits best, but I am sure it will be moved if better suited elsewhere.
Laptop is Thinkpad T430 2344-BZU with 1vyrain mod bios running linux mint 20 xfce
Since the bios mod, at boot,I have an "error communicating with TPM chip"
It continues to boot and everything seems to function properly.
Below is dmesg grep tpm info

Code:
[email protected]:~$ dmesg | grep -i tpm
[    0.537747] tpm_tis 00:05: 1.2 TPM (device-id 0x0, rev-id 78)
[    0.585818] tpm tpm0: TPM is disabled/deactivated (0x6)
[    0.673760] ima: Error Communicating to TPM chip
[    0.685758] ima: Error Communicating to TPM chip
[    0.693744] ima: Error Communicating to TPM chip

I have been reading what I can find about TPM, but am still quite ignorant about the scope and impact of disabled/deactivated TPM chip. This is a personal laptop and is not used in an enterprise IT network environment.

What happens if the TPM chip is disabled/deactivated ?
Are there any security concerns with this disabled/deactivated ?
Thank you for any shared insight
