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 or solid-state drive with a scheduled fee.
