back in the 90' I was using a software called "KillCMOS" what it does is reset the cmos/bios back to default manufacture, I don't know if it will work on your or not. But it is not hurt to try it.

A BIOS password on a modern system is very difficult to remove. If it was easy to remove it would be of little value. In most cases only the manufacturer will be able to do this, and then only if you can prove you are the original owner.

The utilities that worked on older system will not work, neither will flashing the BIOS.

SONY VAIO PCG-9w6l (VGN-bx546bw)

hi,

Here is my story about my laptop

i am using my VAIO PCG-9w6l (VGN-bx546bw) Laptop since 2-3 years with power-on password and BIOS password, and i try to remove password by changing password to blank (leaving empty) in CMOS security setting then password is changed but my laptop still ask for password, I try to unlock just pressing enter without any typing (leaving blank) but it doesn't accept and i tried to unlock with old password still it doesn't work. Now my laptop becomes locked.

I tried everything, what i know:
removing cmos battery (2 days), finding jumper but i couldn't find, even i can't use BIOS cracking softwares because power-on password is there.

Please, Can anybody help me? please .....

My laptop service TAG is C100YQBP

I've juts done this too on 2 laptops!

Sony laptop and another laptop.

I both set the bios passwords to blank. Saved settings, rebooted, and then they asked for the passwords.

Entering nothing <blank> still doesn't allow me to boot. I just made 2 expensive bricks.
