If the user HDP has been forgotten, check whether a master HDP has been set. If it has, it can be
used for access to the hard disk drive. If no master HDP is available, neither Lenovo nor Lenovo authorized
service technicians provide any services to reset either the user or the master HDP, or to recover data from
the hard disk drive. The hard disk drive can be replaced for a scheduled fee.
