I installed the most recent firmware update (fwdphb07) and run into problems with my T450s:
My displays (two attached via DP, the main display with DP 1.2) stay blank until the windows login screen shows up (no windows is starting screen). The problem is that I have a SSD password so the password dialog is not shown on the external screen.
I downgraded the firmware to fwdphb06 (installed fwdphb03 before, because fwdphb06 does not allow for a direct downgrade) and everything works fine again.
@Lenovo: can you please fix this issue - if you need more information please contact me
@other users with the same issue: try to downgrade the FW
Have a nice day
