Hi,
Are you the one who set up the BIOS password? If not, unfortunately, there's no way for us to retrieved the password. The only way you can reset the password to default settings is to reseat the CMOS battery on the motherboard, its a circular thing that looks like a battery of a watch,sometimes a pin hold it, just detached it then wait for at least 30 minutes then connect it back again,
Note: Before you reseat the CMOS battery,make sure that everything is unplugged on the computer, like AC adapter,battery and all external devices...

Hope this will help...Your response is very much appreciated...

Method 1:-
1. BIOS passwords secure different levels of system access. Lowest level is access control for power management functions, next for BIOS access (BIOS password) and highest level is for PC access (Administrator password).
2. BIOS password is stored in a non-erasable part of the CMOS ('BIOS memory'). On desktop PC's this CMOS is buffered by an onboard battery. Depending on your mainboard layout you'll see a seperate battery or won't see it as it will be integrated in a multifunction chip housing battery, real time clock (RTC) and other components (usually a small black brick on the mainboard).
METHOD 2:

Remove password using common master passwords

Please be aware that most BIOS releases lock your PC completely after entering 3 wrong passwords !

Forgot My Pin Number. how do retrieve it .


Hola Sorry to say but if this is the right one i searched for the manual found
http://download.lenovo.com/UserFiles/UserGuide/en/User's%20guides%20and%20manuals/K1/Lenovo%20IdeaPad%20Tablet%20K1%20Hardware%20Maintenance%20Manual.pdf
IT said as following:

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.



Sorry hope this helps a little good luck

Supervisor password


A Supervisor password protects the system information stored in the BIOS. The user must enter the Supervisor password in order to get access to the ThinkPad BIOS Setup Utility in order to change the system configuration. If the Supervisor password is forgotten there is no way to reset it to enter the BIOS configuration. Setting a Supervisor password automatically sets the master Hard drive password. The following is the icon that comes up in the upper left corner if a Supervisor password is set:
A forgotten Supervisor password will prevent access to the ThinkPad BIOS setup utility. To regain access, the system will need to be serviced to have the system board and hard drive replaced. Proof of purchase is required, and this repair is not covered under the warranty.
