Re: sony vaio VGN FJ290P password reset sony vaio VGN...
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.

Remove the battery, remove the power cord and start taking the laptop apart. You will need to remove the CMOS battery located on the motherboard and let it sit for an hour or two. Then but it all back together. The CMOS battery is a silver battery about the size of a nickel.
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
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.
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.
To reset the BIOS password read the information from this link.
In case of your Sony VAIO 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 and I wouldn't recommend doing it especially if it's under warranty.

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.
