Passwords - ThinkPad 390X / i 1700 - (2624, 2627)

  How to Disable the Passwords

There are three passwords used at a typical customer site:
the Setup password , the HDD password , and the Power On password .

•  Power On password reset:
  1.  Power off the computer.
  2.  Remove the battery pack and AC Adapter.
  3.  Remove the backup battery (RTC) for 20 minutes or use a screwdriver to touch the  backup battery (RTC) for 1 second.
  4.  Put back the backup battery (RTC).
  5.  Power on the computer and wait until POST ends.
  6.  Verify that the password prompt does not appear.

•  Supervisor and HDD passwords:

   The Supervisor password and Hard Disk password  (Hard Disk1 and Hard Disk2) are security features
   that are used to protect the system and the hard disk  drive data from unauthorized access.
  No overriding capability is provided, so it cannot be replaced if they are forgotten.

  •  If the customer forgets the Supervisor password, the system board must be replaced.
  •  If the customer forgets the Hard Disk password, the hard disk drive must be replaced.
