I have a Thinkcentre desktop. I wanted to enabled bitlocker, so I activated the TPM chip in bios, ran the bitlocker wizard. I checked the system check box, rebooted, and after the reboot I get an error: "Bitlocker could not be enabled. The TPM was unable to unlock the drive. Either the system boot information has changed after choosing bitlocker settings or the PIN did not match....".
At any rate, I have successfully enabled this on several machines and understand how it works overall. I'm at a loss, and Lenovo tech support isn't much help. Does anyone have any suggestions? And yes, I updated the BIOS as well.
