the Admin password?

Password which has the same digits is created in the Admin Mode cannot be
changed or deleted
Q: Why could I not create recovery media using the ThinkVantage Rescue and
Recovery software?
A: Ensure that your Secure Hard Drive could be accessed correctly. If you still
cannot create recovery media, format the Secure Hard Drive with NTFS file
system of your computer and try again.
Q: Why could I not initialize, partition or format the Secure Hard Drive?
A: Ensure that you have administrator privileges. You can use only the
administrator account to initialize, partition or format the Secure Hard Drive in
the Admin Mode.
Q: Why could the system not boot from the Secure Hard Drive after I entered
the User Password?
A: The Secure Hard Drive is a full disk encryption device that requires several
seconds to unlock after you enter the correct User Password.
1. Press F1 or F12 to pause the boot process to enable the Secure Hard Drive
several seconds to unlock itself.
2. Enter the correct User Password and the indicator light turns green.
3. Press Ctrl + Alt + Del and the Secure Hard Drive will remain in the User
Mode during the reset process and you can then boot from the drive.
Q: Why could the system not boot from the Secure Hard Drive when it is
attached in a dock?
A: As the dock will shut down the power of USB port during warm boot, the
Secure Hard Drive could not unlock itself in limited time. An easy solution is
to attach the Secure Hard Drive directly to computer (not the dock), and this
will enable the computer to boot from the Secure Hard Drive during a
recovery process.
