Hi, My T410s was working fine with bitlocker, but now it is asking for the unlock codes every time I restart. Any ideas? I recently upgraded BIOS to 6UET42WW (1.22). Could that have caused it?

Cheers,
Brad

Yup. Just temporarily disable, then re-enable Bitlocker on the drive. (I believe it's under "Manage Bitlocker" in the Start Menu.)

Bitlocker decryption keys (in TPM) is invalidated once any hardware changes are made.
