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 passwords 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, hybrid drive, or solid-state drive with a scheduled fee.
