The Just Answer system is an honor system and you are not forced to accept an answer. That said, the only way I get paid is to answer your question and for you to accept it.

I have answered your question to the best of what is technically possible. If there was another option, I would have given it to you, but what you are looking for is not possible. To that end, I answered your question in that you asked how to reset the password and I provided you with the least invasive solution that will work.

There would be an easy way if you knew the password. Since you don't know the password, that is not an option. With a Sony Vaio, reseating the battery is not even a guarantee that it will work as different Vaios have different levels of security and some burn the password onto an EEPROM that you have to remove and solder a new one on. I know this is a pain, but there is no easy solution to this...if there was, the BIOS password wouldn't be much of a security measure.

I know you aren't going to pay me and that is entirely your choice. I responded because I simply want to help you as best is possible for this situation. You asked a question and you got an answer...the correct answer. There was no guarantee that you would get the answer you wanted, but you did get the correct and only answer. I have put time into this researching this for you and my time costs money and takes me away from other things. I am disappointed that you don't value that, but it is your choice.
