From what I've found, your computer has a Phoenix BIOS.
Most manufacturers have a master password to be used in
situations like you're in. The following can be found
on the web as having been used successfully:

phoenix

PHOENIX

bios

BIOS

CMOS

CMOSPWD

setup

If those don't work, the following pages discuss other
options, such as clearing the CMOS by temporarily 
changing a specific jumper setting on your motherboard,
or removing the CMOS battery, both of which erase the 
custom settings in the BIOS, including the password:

I have tried all backdoor passwords with no luck, and according to
password crackers " LAPTOP AND NOTEBOOK RECOVERY
 

Most laptop manufacturers have provided additional safeguards for
their computers. We are not aware of any simple BIOS recovery program
that works on laptops, nor are we aware of any simple backdoor
passwords for these machines. BIOS passwords in most laptops are
stored in a special chip on the motherboard and the only way to bypass
this password is to replace this laptop security chip. Laptop BIOS
passwords cannot be bypassed or reset by removing or shorting the CMOS
battery. Further, doing this may cause other system errors and
complicate the recovery or your system. "

Apparantly there is no easy fix....

That's certainly not good news, but I wouldn't be too quick
to give up all hope. Password Crackers is, after all, trying
to sell you a service, and while they're clear that pulling
the batteries and using backdoor passwords won't work, they
don't really address the idea of resetting dipswitches, as
is discussed in this article from LabMice.net with reference
to laptops as well as desktops:

"Using the Motherboard 'Clear CMOS' Jumper or Dipswitch settings"

"Many motherboards feature a set of jumpers or dipswitches
 that will clear the CMOS and wipe all of the custom settings
 including BIOS passwords. The locations of these jumpers /
 dipswitches will vary depending on the motherboard
 manufacturer and ideally you should always refer to the
 motherboard or computer manufacturers documentation. If
 the documentation is unavailable, the jumpers/dipswitches
 can sometimes be found along the edge of the motherboard,
 next to the CMOS battery, or near the processor. Some
 manufacturers may label the jumper / dipswitch  CLEAR -
 CLEAR CMOS - CLR - CLRPWD - PASSWD - PASSWORD - PWD."

"On laptop  computers, the dipswitches are usually found
 under the keyboard or within a compartment at the bottom
 of the laptop."

If that doesn't work out...

The other thing I'd suggest is to open up the laptop and
see if you can identify the precise manufacturer and model
number of the motherboard. Some laptop manufacturers will
use more than one motherboard manufacturer and/or model
in the same model laptop, so the best way to identify the
exact one you have is to eyeball it.

If the manufacturer and model number is not evident, you
might try calling Sony with the serial # for you PC and
see if they can tell you more about the motherboard, and
even how to reset the BIOS password.

Once you have the motherboard manufacturer and model number,
it may be possible to locate documentation for that board, or
boards made by that manufacturer, or to research a method
specific to that board, or contact the manufacturer for input.

Let me know where this takes you...
