Bios Chip Where can i locate my bios chip off my laptop wich is a sony vaio 2002

The BIOS password, must be reset at a Sony Service center: View Document 0 185182553. I can't find locations, so contact Sony Technical Support for help: Sony eSupport - Electronics - Select Your Model.

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

The BIOS password is probably the Power On Password.
This method may not work. Remove the BIOS battery for 20 mins until the charge in the BIOS is depleted. Insert the BIOS battery go into the BIOS setting and set the Date and Time etc.
If this does nor work then the BIOS password is stored on an EEPROM chip and removing the BIOS battery won't work and there is probable no backdoor passwords.
The Sony support maybe able to offer a solution, check the support WEB site..

Hi,

To reset the bios password on your laptop, you will need to remove the cmos battery on your laptop for some minutes and insert back, the cmos battery is located on the motherboard of your laptop, once the cmos battery is removed from the motherboard for some minutes, the bios password will be reset, and that fix the problem.

Unlike desktop computers, they rarely make it so that you can delete or reset your BIOS password in a laptop. To do this usually requires an IC chip to be removed from your motherboard and then replaced. If you can find someone to do this, then it will most likely cost $150 or more. There are some who claim to have a Break or Work-around for removing bios passwords. I've very rarely had this work for me. Here's a link to a web page that puts it into steps to follow that you could try. Click here.

go to www.sony.com click on support and then drivers and then type in you model it will take you to the drivers page and it is concidered a driver

It should be located somewhere on the motherboard wich means pulling the computer completely apart which unless you know what you are doing may be a little difficult for some, but not inpossible.

Hello, if you have an intel m processor for your sony then u are somewaht out of luck. the base memory is 256 megs and it is not in the motherboard but rather integrated in one of the slots itself, that means if u put a 512 mb chip into that certain slot it will only read 256. a lot of people are mislead into thinking they can put two 512s and get a gig of memory, but not true, at least not with most of the sony intel processors. find the base slot by switching chips around, then leave the 256mb chip there. then u can add a 512mb to the expandable slot and get over 700bytes. if u can find a 1gb compatible stick,then try that the same way, leave the original hynix base slot chip in and add the 1gb, if u can find one, then u will have a little over 1280 of which u can up the video graphic usage up to 128 in the bios, and have your 1gb in memory. if u find a 1gb memory chip that work,drop a line as to what brand and size u used
