3. Remove the battery
4. Get flat screw driver then put it between two pins where the cmos battery attached.
5. Hold it for 10 to 15 sec.
6. Put the cmos battery back and the motherboard
7. Power it up and holla the bios setting has been reset to default.
restart the laptop HOLD the keys fn+f1 or f2 depend of your model, mark, and enter the BIOS setup, and make the restore password as indicated in the BIOS page. God bless you

How to remove and unlock hard drive password? Is there any software to recover hard drive disk password? Where to download hard drive password cracker? Is it possible to reset the hard drive password?
According to Lenovo and many other manufacturers' website, if you forget your hard drive or hard disk password, there is no possible way to reset your password or recover data in the hard disk drive. Basically the hard drive is unusable. Scary right? However, this is often not true.
Most people are not aware that most hard disk drives have the ability to set a hardware password, just like the Bios password for motherboards, thus making the drive completely inaccessible unless a correct password is provided during the BIOS POST test. Usually these features can only be found in laptops, this is when you set a password on your notebook, the hard drive together with the motherboard becomes locked.
Most experts would say if you forget the original HDD or Bios password, there is no way of restoring it by generic system tools. Unlike the Bios password where there is a master key or with the removal of the bios battery, the password is erased from the flash memory thus the settings is restored to factory settings without the password, however, this does not applies to hard disk.
To reset the BIOS password read the information from this link.
In case of your Lenovo laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.
go to safe mode and delete the user account or inactivate the pw. if still not successful push the One key recovery, that is the button beside on/off button. (full factory restore. all your files will be gone)
