Ну так Power-On pass и убрал (можно было просто перемычкой как написано выше), а супервизора остался

The supervisor password is a tool provided for the system administrator to control many ThinkPad computers. The supervisor password is set by the system administrator and it is not required for users. Users can start the computer without providing the supervisor password. The supervisor password is required only to access Easy-Setup.

– The system administrator can use the supervisor password to access the computer even if you have set a power-on password. The supervisor password overrides the power-on password.
– The supervisor password has priority over the hard-disk-drive password. The hard disk is protected by the supervisor password so that unauthorized users cannot access data on the hard disk.
