SOURCE: how do I get to the CMOS battery on the sony vaio

Carefully open your laptop by unscrewing it.
Lift the back cover and you will see the mother board.
You will see a large flat round battery.
That is your CMOS battery.

SOURCE: Can you tell me where the cmos battery is located

If it is not where you can see a slot on the side or back, I would bet it's under the keyboard. The Sony support page may have the answer.

How to replace internal battery for Sony PCG-955A


If you mean the cmos battery you will probably need to take the laptop apart - if you are lucky it may be under the keyboard - look at the screws on the back and see if any show symbols for keyboards.

There is a vaio manual here.

CMOS battery Sony Vaio PCG-4G1L


Instructions
    • 1 Open the Vaio screen until you can easily access the keyboard.
    • 2 Locate the plastic bar that borders the top of the keyboard. Insert the flat head screwdriver at one end of the bar and gently pry it up until you can grip the edge with your fingers.
    • 3 Pry the other side of the bar up with the screwdriver and pull out the entire bar, being careful to mind the ribbon cord that connects the keyboard to the computer.
    • 4 Remove the two screws on either side of the keyboard that secure it to the computer. Slide the keyboard up and place it to the side.
    • 5 Remove the four screws on the exposed metal plate that covers the motherboard and remove it. You should now see the CMOS battery in the bottom-right-hand corner of the motherboard.
    • 6 Remove the battery by gently pulling it up and off the motherboard. Replace it with the same model battery (available at any computer store or online). Reassemble the computer the same way you took it apart.

I want to clear CMOS


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

you might get some more information from the manual

hope this helps

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.
