Over this past week I had a job come in the shop of a Sony Vaio laptop that had a bad motherboard. I had searched on Ebay for a cheap buy and settled on someone who had the same motherboard for about $100 less than anyone else. When I received the motherboard I promptly installed it , upon powering it up I was faced with a password prompt. Dammit! The motherboard had a BIOS password that wasn’t mentioned in the auction. Now being that I know most known methods for bypassing BIOS passwords, Sony has no known method of removing the password. I talked to a few friends and was forwarded to http://spunlock.com .

I was a bit weary at first about paying for a service , but the customer needed their laptop back that day to go on a trip. So getting the customer’s O.K. I purchased the BIOS cracking service.In order to get the correct challenge response BIOS code for most laptops you needs to enter the password incorrectly 3 times, after the third time , the BIOs should spit back a challenge code, this is what they need in order to crack the code.

After sending the payment and challenge code,much to my amazement 1 1/2 hours later I was opening an email with my code to remove the BIOS password. I punched it in and I was now watching Windows starting up. Spunlock has BIOS cracking support for many laptop brands like Dell,Fujitsu,Sony (of course) and more. So for you Techs and others who got burned on ebay, or people who simply forgot their password , give them a shot, you have nothing to lose, Don’t forget to mention whatsmypass.com in your email to them

This python script generates master passwords which can be used to unlock the BIOS passwords of most Fujitsu Siemens laptops (Lifebook, Amilo etc.) http://dogber1.googlepages.com/pwgen-fsi.py

Toshiba laptops aren’t like most laptops where you can remove the BIOS battery and let it sit for a few hours to reset the BIOS. So what do you do? There are three forms of BIOS password removal being used currently by Toshiba:
1. Parallel port wraparound connector
2. Shorting a jumper, with power and with no power
3. Challenge/Response code

Here’s a .pdf by Fastback68 which appears to to compiled from qasimtoep’s old website explaining how to reset a Dell BIOS password using a paperclip.The laptop that was used in this demonstration is a Model 630 type PPX.

There are a lot of people who have a dell or similar laptop that they are not able to use because of a special password chip that can’t be cleared by resetting the CMOS using software or by removing the battery. (more…)

BIOS passwords can be add extra layer of security for desktop and laptop computers, and are used to either prevent a user from changing the BIOS settings or to prevent the PC from booting without a password. BIOS passwords can also be a liability if a user forgot their passwords, or if a malicious user changes the password. Sending the unit back to the manufacturer to have the BIOS reset can be expensive and is usually not covered in an a typical warranty. However, there are a few known backdoors and other tricks of the trade that can be used to bypass or reset the BIOS password on most systems.
