Hi @jicsoft,

Welcome to HP Support Community.  

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

If you're facing BitLocker issues after resetting the BIOS on your HP Laptop 15-dwxxx, there could be a few reasons behind it. Resetting the BIOS can sometimes result in changes to hardware settings, which can affect the way BitLocker works. Here are some steps you can follow to troubleshoot and resolve the problem.

• Check BIOS Settings: Make sure that the BIOS settings are correctly configured to support BitLocker. Some important settings to verify are Secure Boot, TPM (Trusted Platform Module), and UEFI/Legacy boot mode. These settings should be set to the recommended values for BitLocker to function correctly.
• Check TPM Status: BitLocker relies on TPM to store encryption keys securely. Verify that the TPM is enabled in the BIOS. If it was enabled before the BIOS reset, ensure it remains enabled.
• Clear TPM: In some cases, resetting the BIOS might cause the TPM to become non-functional. To resolve this, you may need to clear the TPM and re-initialize it. The steps to do this can vary depending on your laptop model, so refer to your laptop's user manual or HP's support website for instructions on how to clear the TPM.
• Recovery Key: If BitLocker is prompting you for a recovery key after the BIOS reset, it means that the encryption keys cannot be accessed. This can happen if there have been significant hardware changes or if the TPM is not functioning correctly. If you have a BitLocker recovery key, use it to access your system. The recovery key is typically a long numerical sequence that you might have saved during the initial BitLocker setup.

I hope this helps. 
 

Take care and have a good day.
