I recently reset my Lenovo IdeaPad 1 15ALC7 running Windows 11, and now every time I start it up, I'm prompted for the BitLocker recovery key. While I have the key, I'm concerned because it seems my TPM (Trusted Platform Module) is disabled and not being recognized. Can anyone help me figure out how to resolve this issue?

I had a similar issue after updating my BIOS. What worked for me was downloading the manual BIOS update from Lenovo’s website, then re-enabling the TPM option in the BIOS setup. This fixed my problem, but keep an eye on it to ensure it stays enabled because it has a tendency to disable itself sometimes.
It sounds like a BIOS setting might be causing the problem. Before making any changes, ensure you have backups of your important data, as adjusting system settings can lead to data loss. If your laptop is still functioning, an alternative is to temporarily swap out the drive and do a fresh Windows installation. That way, you can sort out the TPM issues later without losing access to your files.
