Question about Sony VAIO CS VGN-CS220J/T Notebook
To reset the BIOS password read the information from this link.
In case of your Sony VAIO 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 and I wouldn't recommend doing it especially if it's under warranty.
