How to remove the hard disk password

Attention: If User only mode is selected and the user hard disk password has been forgotten and cannot be
made available to the service technician, neither Lenovo nor Lenovo authorized service technicians provide
any services to reset the user hard disk password, or to recover data from the hard disk drive. To put the
system back to operational status, the only Lenovo and Lenovo-authorized service solution would be to
replace the hard disk drive or solid-state drive with a scheduled fee.
To remove a user hard disk password that has been forgotten, when the supervisor password and the master

New Password field blank, and press Enter twice.
