trusted platform module

[js08820]

There is an issue with Trusted Platform Module data. I started to receive this after a bios update. It is prompting me to  press Y to reset whole TPM or N boot with current TPM data. It further says Note: Bitlocker may be require the recovery key to boot to windows. 

This message is more of an annoyance as when I elect N to boot with current TPM data it boots just fine. I do get an anoying sign in require notification for a former work Office 360 account. Don't know if the two are related.

I do have the recovery key. Will I loose any data stored?

Hi @js08820,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand the Trusted Platform Module (TPM) message you're seeing usually indicates that the BIOS update has caused changes to the TPM settings, prompting you to either reset the TPM or continue using its existing data. 

Here’s what each option entails and what you can expect:
 

Selecting "Y" to Reset the TPM:

• Resetting the TPM will clear any stored information on it, including encryption keys.
• Impact on BitLocker: Since BitLocker relies on the TPM, this reset will require you to enter the BitLocker recovery key the next time you boot up. You won't lose any data stored on the drive, but you’ll need to re-link the TPM with BitLocker, which may involve re-encrypting the drive if prompted.
• Impact on Office 365 Sign-In: If your work Office 365 account was managed by your previous workplace, the reset may trigger additional login requirements due to security changes. It’s worth unlinking or removing that account if it’s no longer in use to prevent ongoing sign-in prompts.

Selecting "N" to Boot with Current TPM Data:

• By choosing "N," you're telling the system to use the existing TPM data, which allows you to continue booting without resetting the TPM. However, this option will likely keep triggering the prompt every time you start your computer.

To proceed with minimal disruption: Since you have your BitLocker recovery key and no data will be lost on the drive itself, you might consider:

• Selecting "Y" to reset the TPM to remove the message permanently.
• Once you reset it, enter the BitLocker recovery key when prompted.

After that, BitLocker should work normally, and you’ll avoid the recurring TPM prompt at startup. Let me know if you need help unlinking the old Office 365 account if that prompt persists!

I hope this helps. 

Take care and have a good day.
