I'm sorry to say that there is no better solution to your problem without the use of a password disk.

I'm assuming you mean the bios password. Turn off the computer. Remove the power supply. Remove the battery. Remove the CMOS battery. Hold the power button for 10 sec to drain residual charge. Plug the computer in and boot. The password should be disabled.

The laptop is Bios Password Locked, who ever you bought this from must know the administrative password, because the computer will remain locked until this is remedied and you will not be able to restore original settings without the password. If the seller can't provide it, I would return it expecting a refund. Sony charges $100.00 to correct this and you must be the original owner. There are other services that claim they can help and charge a fee.
