Bitlocker TpmandPin Encrypted X230 in Lockout State
We have a ThinkPad x230 with Bitlocker encrypted. Laptop is using TPMandPin is used. OS is Windows 8
The issue now, we reach the tpm wrong pin threshold and last Sunday laptop got lock and we are able to only open it after the lockout state Monday afternoon. To be honest I'm not aware of this TPM behavior. So the user really want to show me what happen so we reproduce and intentionally put a wrong pin.
Now, laptop is still not accessible until this time. The thing is, we cleared the tpm from bios. So even using the correct pin, it tells you that it's a wrong pin.
Apparently, the recovery password was taken forgranted and we don't have a copy.
I was hoping someone can provide more information on how to tacle this and ultimately be able to recover the laptop.
