The BIOS password can normally be removed by disconnecting your laptop from the mains supply and by removing your laptop battery and the BIOS lithium battery.
You can the short out the BIOS battery connections or leave the laptop alone for 1/2 hour or so. Then connect the mains supply only and power up your laptop, you should now be able get into your BIOS. Power down again and reconnect both batteries, power up laptop again and reconfigure your BIOS again.

Open your CPU cabinet after switching OFF the power and then try to locate the CPU battery which can be found very easily. Once you locate your battery you need to remove it once and restart your PC without the battery.
Note : Once you remove your battery from the mother board, you will find that all your time settings in your computer would be lost, and some softwares may stop working which are based on your computer time.

The BIOS password is probably the Power On Password.
This method may not work. Remove the BIOS battery for 20 mins until the charge in the BIOS is depleted. Insert the BIOS battery go into the BIOS setting and set the Date and Time etc.
If this does nor work then the BIOS password is stored on an EEPROM chip and removing the BIOS battery won't work and there is probable no backdoor passwords.
The Sony support maybe able to offer a solution, check the support WEB site..
