The CMOS is a block of static RAM that will lose its data if power is removed.
most newer laptops are using a small block of Flash RAM (perhaps a block of addresses within the Flash BIOS chip itself) or other type of EEPROM chip to store the password.

No amount of removing batteries and pressing power buttons will change it

No access panel for that. That is located on the motherboard. You will have to take of the keyboard to get access to it.

I have set the password for administrator when i entered the bios set up. you can change its setting but not the configuration unless you've entered the password. you can't change the password with a new one if you cant enter the old password. Next time dont forget your password because laptops has its security even when stolen you cant open its bios set up if its protected by password. CMOS battery is in the mother board. You need a service technician to open your laptop to reset the bios setup battery.

HAVE TRIED CHANGE THE CMOS BATTEWHAT CAN I DO NXTRY TO REMOVE BIOS PASSWORD BUT IT COUDNT WORK,?

Sony Vaio PCG and some Vaio VGN Series use the last 7 digits of the laptop serial number to calculate the bios master password. The serial number for a Sony Vaio is often located on the bottom of the laptop on a white sticker. The serial number may also be found by removing the battery and checking in the battery compartment. The link to unlockbiosrecovery.com below works on the following models:
PCG-C, PCG-F, PCG-GR, PCG-GRS, PCG-GRT, PCG-GRV, PCG-GRX, PCG-GRZ, PCG-N, PCG-NV205, PCG-QR, PCG-R, PCG-SR, PCG-SRX, PCG-TR, PCG-V, PCG-VX, PCG-X, PCG-Z, VGN-B, VGN-FS, VGN-S, VGN-T, VGN-TX1, VGN-X
I use http://www.unlockbiosrecovery.com/Unlock_Sony_Bios.php
For $20 they use the last 7 digits of the laptop serial number to calculate the bios master password and then email it to you in an hour. They guarantee it to work and you can call them if you have a question.
