IdeaPad Tablet K1 Hardware Maintenance Manual

When you use the recovery discs to boot your computer, the system will enter 

the user interface for system recovery automatically. Please follow the prompt 

to insert the backup discs to complete the whole recovery process. 

Note:

 

The recovery process might take up to 2 hours. 

Passwords

As many as two passwords may be needed for any Lenovo IdeaPad computer: 

the power-on password (POP) 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.

Supervisor password 

A supervisor password (SVP) protects the system information stored in the 

BIOS Setup Utility. The user must enter the SVP in order to get access to the 

BIOS Setup Utility and change the system configuration.

Attention:

 If the SVP has been forgotten and cannot be made available to 

the servicer, there is no service procedure to reset the password. The system 

board must be replaced for a scheduled fee.
