Passwords

power-on password (POP), the hard-disk password (HDP), and the supervisor

Attention: 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 servicers 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.
Supervisor password:
A supervisor password (SVP) protects the system information stored in the BIOS

servicer, there is no service procedure to reset the password. The system board
must be replaced for a scheduled fee.
