SOURCE: Bios Password Reset
The only idea I have is to find and disconnect the CMOS back-up battery after removing main battery and unplugging the AC adapter. That SHOULD clear the bios completely, wiping out the password, the date, and everything else.
I know this works on desktops, and most laptops, but no promises, and the cmos battery may not be easy to access.
You should probably leave the battery unhooked for at least 1-2 minutes to be sure it clears.
Hope this is some assistance!

SOURCE: password for entring my bios
BIOS Passwords Basic settings on your computer such as how many and what kinds of disk drives you have which one are enabled and which are disabled and which ones are used for booting are held in a CMOS chip on the mother board. A tiny battery keeps this chip always running so that whenever you turn your computer off, it still remembers its instructions. A common method of entering the BIOS is pressing the Del key at Bootup other common methods are Ctrl +Alt +Esc and Ctrl + Esc. Most computers have a BIOS which can be configured to ask for a password as soon as the computer is switched on. If the Ask Password option is enabled then as soon as the PC is switched on a Dialog box welcomes you and asks you for the password. You cannot override this and there is no way of disabling this because to enter the BIOS you need to know the BIOS password. So what do you do? Disable it. Now to Disable the BIOS password you need to enter the BIOS. But as soon as you enter the BIOS the BIOS asks for a password. Now the most common method of overriding this password prompt is by trying out the default BIOS passwords. Some common passwords are: Lkwpeter j262 AWARD_SW AWARD_PW Biostar Many BIOS also have their default password that can be tried. "j262" opens most versions of Award BIOS it works about 80% of the time. "AWARD_SW" and "AWARD_PW" work on some computers as well, but much less often. In some BIOS shift+s y x z also works. The best way to find out the default passwords of various BIOS is to search at http://astalavista.box.sk which is the best search engine for security related matter Well if the default passwords did not work them get ready for some serious Hacking stuff. Now as the default BIOS password did not work we will try to reset the BIOS to its default settings so that it asks for no password at all. So to do following: First you have to open the computer and then look for a round lithium battery, it probably looks like a silver coin. So remove the battery and after 30 seconds or so put it back. Some computers may also require you to reset the jumper, so look for a 3-pin jumper and reset it. For example, on most machines you will find a three-pin device with pins one and two jumpered. If you move the jumper to pins two and three and leave it there for over five seconds, it will reset the CMOS. When you boot the machine some BIOS may give an error saying that the BIOS was reset or tampered with, but that is not such a big problem

First off is there two passwords one for bios one for gaining access to the O/s ?
If its a system startup password basically you need to take the battery out for a minute and replace ( Easier to do on desktops )
or Flash the bios can't promise that would work or be easy on a laptop either. Would have to google that.

The best way for the Sony is to remove the cmos battery for at least 30 minutes. Remove the main laptop battery and leave it out. Make sure the power adapter is not attached. The cmos battery can be reached after removing the keyboard and is attached to the motherboard vis a small cable. If you have a "jumper" that come equipped on hard drives to jump the pins on the back, you can "short" the pin connections on the cmos battery socket, power the laptop up using the ac adapter and letting the computer go through the bootup process. When this happens power the laptop back down, take the jumper off and replace the cmos battery. Power back on with just the ac adapter and boot the computer. If the laptop still askes for a bios password just hit enter and it should allow you to log in. Once in go into the bios and reset the date and time. Once that is done power down and replace the main battery. Reboot the laptop and let Windows load.

There are 2 ways you can reset your bios.
1. On the motherboard there is a small watch battery. Remove this battery along with the power cable from the power supply. Hold down the power button to fully discharge the system. Wait 2-3 minutes then reinstall the battery and plug in your system. Your reset is now complete
2. Some motherboards have a 3 pin jumper by the battery. Lets say that the jumper is on pins 2 and 3. Remove the jumper while the machine is OFF and place onto pins 1 and 2. Power on your machine for a minute. (Note: Your system will not POST). Shutdown your machine and put the jumper back to pins 2 and 3. Your reset is now complete
This is a great troubleshooting step for those of you having POST issues or no POSTing at all. Like other troubleshooting steps, this will not always work but usually will depending on the problem.
Please let me know if you have any further questions or concerns.
