Passwords

As many as three passwords may be needed for any Lenovo IdeaPad
computer: the power-on password (POP), the hard-disk password (HDP), and
the supervisor password (SVP).
If any of these passwords has been set, a prompt for it appears on the screen
whenever the computer is turned on. The computer does not start until the
password is entered.
Exception: If only an SVP is installed, the password prompt does not appear
when the operating system is booted.

Power-on password

A power-on password (POP) protects the system from being powered on by
an unauthorized person. The password must be entered before an operating
system can be booted.

Hard-disk password

There are two hard-disk passwords (HDPs):
•
•
Note: There are two modes for the HDP: User only and Master + User. The
Master + User mode requires two HDPs; the system administrator enters both
in the same operation. The system administrator then provides the user HDP to
the system user.
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.

The recovery process might take up to 2 hours.
User HDP—for the user
Master HDP—for the system administrator, who can use it to get access to
the hard disk even if the user has changed the user HDP
