Passwords<br />
When you use the recovery discs to boot your computer, the system will enter<br />
the user interface for system recovery automatically. Please follow the prompt<br />
to insert the backup discs to complete the whole recovery process.<br />
Note: The recovery process might take up to 2 hours.<br />
As many as two passwords may be needed for any <strong>Lenovo</strong> computer: the<br />
power-on password (POP) and the supervisor password (SVP).<br />
If any of these passwords has been set, a prompt for it appears on the screen<br />
whenever the computer is turned on. The computer does not start until the<br />
password is entered.<br />
Exception: If only an SVP is installed, the password prompt does not appear<br />
when the operating system is booted.<br />
Power-on password<br />
A power-on password (POP) protects the system from being powered on by<br />
an unauthorized person. The password must be entered before an operating<br />
system can be booted.<br />
Supervisor password<br />
A supervisor password (SVP) protects the system information stored in the<br />
BIOS Setup Utility. The user must enter the SVP in order to get access to the<br />
BIOS Setup Utility and change the system configuration.<br />
Attention: If the SVP has been forgotten and cannot be made available to<br />
the servicer, there is no service procedure to reset the password. The system<br />
board must be replaced for a scheduled fee.
