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.

To break the bios password is no problem.

All you need to do is just to power off your laptop and remove the battery.

Get a screw driver to unscrew all the screw that will lead you to your laptop board. When you get to the board, remove the cmos battery and try to screw your laptop back, put your battery and power on without the cmos battery, leave for sometime to power up, your bios will go back to default and will never ask for password again.

After it has stay for a while, you can now unscrew back and put the cmos battery.

Makesure you screw back all the screws from where they are been removed.

After all this you can enjoy your laptop and still set the bios password if you want.

Please if you cannot do all this yourself, get someone who can help or a repairer in other not to complicate issues.

Take care.

Need one time bios password for sony vaio laptop, electrical storm jacked up the operating system lost bios password, need to run diagnostics model numbe vgn nr140e can you help

in order to reset the bios password you will need to remove the cmos battery and leave it out for about 15 minutes. This allows the stored up charge in the capacitors to dissapate, and after they discharge is should be reset back to original factory bios setting.
once into your bios, make any changes needed for specific hardware before you reboot computer and go into diagnostic testing mode.

On a desktop this is usually as easy as setting a jumper to reset it but on a laptop it is alot trickier. from what my research has told me Sony will help you with this issue with Tech support. You will need a valid proof of purchase for them to help you. If you registered the laptop when it was bought or if you have a warranty on it through who you purchased it from, even Sony this would make proof of purchase that much easier Click this link HERE for the 1800 number to Sony. There are instructions there. I hope this helps.

How to Change/Reset a BIOS password Posted on 30 December 2008
Tags: Tech News, Tutorials If you are a normal computer user who has forgot his BIOS password and you are unable to access to your BIOS, then you need a simple way to change your BIOS. Its not that hard because you just need a simple trick to reset your BIOS password.
Open your CPU cabinet after switching OFF the power and then try to locate the CPU battery which can be found very easily. Once you locate your battery you need to remove it once and restart your PC without the battery.

cmos-battery-check.png Note : Once you remove your battery from the mother board, you will find that all your time settings in your computer would be lost, and some softwares may stop working which are based on your computer time.

You need to shut down your PC again and now add back the battery which will enable you the time saving feature and also reset your BIOS password.
