Or, Error while enabling BitLocker in Windows 10 Acer laptop
“the Bitlocker encryption key cannot be obtained from the trusted platform
module (tpm)”.
Or, Enable Trusted Platform Module (TPM) option is grayed out in BIOS – Acer TMP 257-M-521.
Or, BitLocker encryption asking for PIN instead of password while
enabling BitLocker Encryption.
Or, How to force BitLocker to use Password instead of PIN?
Error Message Details:
Bitlocker could not be enabled
The Bitlocker encryption key cannot be obtained. Verify that
the Trusted Platform Module (TPM) is enabled and ownership has been taken. If
this computer does not have a TPM, verify that the USB drive is inserted and
available.
C: was not encrypted.
Descriptios:
Some of the articles suggested to go to tpm.msc > go to action
> Turn off TPM from there. and the most frustrating thing was, there was no
option available there to Turn off or Turn on TPM from this action menu. Tried
everything like, gpedit.msc to bypass TPM, Clear TPM, Change Owner Password
from TPM management page etc. nothing worked.
L
One thing more, this is one culprit which was forcing me to
enter TPIN instead of BitLocker startup password while enabling Bitlocker on my
laptop with Windows 10 OS.
What Worked well?
If you want to disable TPM completely for your computer, you
should do it from BIOS. In My case, I am using Acer TMP 257.
To disable TPM from BIOS of “Acer TMP 257” laptop,
please follow below steps.
Steps: Reboot
your PC > On the booting screen, press F2
to enter in BIOS > Go to Security tab > Set Supervisor
Password
Now Go to Change TPM
(TCM) State: > Hit Enter > Select Disable
Again go to “Set Supervisor
Password” > Hit Enter > Enter your current password > Leave other
fields blank and Hit Enter > Reboot your laptop and you are done with
Disabling TPM from BIOS of your acer laptop.
Now you can proceed with enabling BitLocker with password
configurations.
