Most laptop bios batteries are not replacable. They require you to take the laptop to bits, and alot are soldered onto the motherboard.
It is very unusual for a laptop cmos battery to die.

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.

Sony vaio pcg-272l all in one with catv connection bios screen password can't get pass it is there a soloution


To reset the BIOS read the information from this link.

In case of your laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.

Cannot find bios for sony vaio PCG-K23


If you can't find it, how do you know it exists? I don't see it on the Sony Website
If you were instructed by Tech Support to upgrade the BIOS, then they should have provided information on how to obtain it.

Internal fuse need replacing


Sorry, but i don't think there is fuse on motherboard.
More likely its a loose DC socket cable to motherboard or faulty AC adapter.
If Dc - ok, AC - ok, then its a faulty motherboard.
