SOURCE: 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.

I m having trouble with my SONY VAIO (VGN-FE770G). i forgot my bios password. kindly send me a solution.


The most common way that we know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing the Cmos battery for 30 minutes from the motherboard. Another way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the battery power, the BIOS/CMOS settings will be erased. Hope this helps

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.

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.
