Re: recovering password or reseting

Well the failsafe way to do that is to remove the CMOS battery from the motherboard. But that involves opening the case to the laptop and finding/removing it.

Opening a laptop is certainly not an easy thing to do, however.

Another option is to find your model number, go to the SONY website and find the manual. There may be instructions in the manual on how to clear the CMOS password.

Also, there is sometimes a RESET button on the bottom of laptops. (It'll usually require a paperclip to activate it.) If your laptop has that, then it'll most likely clear the CMOS password.

Good luck.

Sony vgn-bx540b bios master password

If you are not the one who set up the Bios password, your options are to keep guessing or reset the cmos.

To reset the cmos, open your laptop and look for a small, silver, circular battery. Make sure everything is unplugged and remove the battery. Then, simply place the battery back into the computer. This should reset the bios and allow you to access it.

Hope this helps!

I forgot BIOS password for SONY PCG-GRX520

The best way for the Sony is to remove the cmos battery for at least 30 minutes. Remove the main laptop battery and leave it out. Make sure the power adapter is not attached. The cmos battery can be reached after removing the keyboard and is attached to the motherboard vis a small cable. If you have a "jumper" that come equipped on hard drives to jump the pins on the back, you can "short" the pin connections on the cmos battery socket, power the laptop up using the ac adapter and letting the computer go through the bootup process. When this happens power the laptop back down, take the jumper off and replace the cmos battery. Power back on with just the ac adapter and boot the computer. If the laptop still askes for a bios password just hit enter and it should allow you to log in. Once in go into the bios and reset the date and time. Once that is done power down and replace the main battery. Reboot the laptop and let Windows load.

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.

Sony vaio VGN FJ290P password reset sony vaio VGN FJ290P

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.
