Like any reasonably developed system, HDD and BIOS systems on laptops/notebooks need enormous protection. Systems that are using password generators in order to protect their security are using different algorithms. Algorithms can vary based on their difficulty level. Current generation laptops require good password generators in order to make their systems as safe as possible.Majority of all laptops are using master passwords (which are unique in each laptop) in order to protect their systems. In order to penetrate the BIOS system one should find a way to disable BIOS passwords. Sometimes it can be very important for the laptop users to know the master passwords of their laptops. However the algorithms to figure out the password are not available to every user.

When a laptop is locked with password, a checksum of that password is stored in FlashROM - this is a chip on the mainboard of the device which also contains the BIOS code and other settings, e.g. memory timings. For most brands, this checksum is displayed after entering an invalid password for the third time. The dramatic 'System Disabled' message is just scare tactics: when you remove all power from the laptop and reboot it, it will work just as before. From such a checksum (also called 'hash'), valid passwords can be found by means of brute-forcing. The bypass mechanisms of other vendors work by showing a number to the user from which a master password can be derived. This password is usually a sequence of numbers generated randomly.

This software generates and calculates the Master Passwords of HDD and BIOS systems of ACER, Dell and Sony VAIO laptops according to their license numbers. The program takes the license numbers of those laptops(which are unique for every laptop) as an input and gives themaster codes of HDD and BIOS as an output. The algorithm was figured out by multiple testing and collecting data from different Internet sources.

This software has been written by Rafayel Mkrtchyan. To try the beta version of the application you can download Password Recovert Tool 1.0.exe file from this repo. To read about the algorithms that different companies used for protecting their Master Passwords download Description.pdf file. I started researching the mechanics of BIOS and HDD password in current generation laptops in 2012. My goal was to create a set of master password generators to disable Basic Input /Output System (BIOS) passwords. After understanging the general algorithm for generating Master Passwords I tried to test them from collected data from different Internet sources.

Generating Master Passwords of different laptops is a constantly developing research field. I originally started my research after reading Dogbert's blog about Master Passwords of HDD and BIOS systems(look at the 'Technical Doc' section). Some groups even suggest for paid services for cracking those passwords(you can find one website if you click on 'Tech Support' section). However my goal was to make this field of research more popular and through open-source development make widely advanced functional tools.

The same goes for new features - it might be best to check the project's direction, existing pull requests, and currently open and closed issues first. Here's some examples of things you might want to make a pull request for:

At some point of time, it happens most often that we forget administration password of our Sony VAIO laptop. Due to this reason, accessing the Windows is almost impossible. You may want to take your laptop to the nearest service center and restore it back to the later factory settings. However, there are some alternatives you can get it back without losing your precious data on your computer. In this guide, we will discuss how to reset Windows password you forgot or lost on your VAIO machine.

Basic Reasons You May Have to Reset Your Sony Laptop Password

Password is often set to secure a Sony laptop but you have to reset it because :

1) Your login password has been hacked by an unauthorized person and your data security is compromised.

2) You forgot your password because of frequent change.

3) You are entering the password you have never set.

Today, we are going to discuss the three important ways to get your VAIO laptop unlocked.

Part 1. Using Password Reset Disk to Reset Sony Laptop Password

Windows offers in-built capability to create password reset disk in User Account option which falls under Control Panel if you have lost your password on Sony VAIO or other computer. Even if you have forgotten your login password or changed it while making the disk, be sure to insert the disk in your USB port and go through the detailed instructions to get it back to previous state.

Obviously, this option will not work if you don't have created password reset disk earlier when password is lost, otherwise the tool is useless. Well, it doesn't matter whether you have password reset disk or not because there are several tools to create a password recovery disk or reset it to unlock VAIO PC.

Part 2: Using System Restore to Reset Sony VAIO Password

If you have just changed your Windows login password and System Restore is running before changing the password, this option can help you get your system back to previous stage when you were using last password that you still remember.

Step 1. Insert system repair disc or Windows Installation DVD in your DVD drive and boot laptop from this disc.

Step 2. Choose your preferred language option, click on 'Repair Your Computer', choose which operating system to restore, and then click 'System Restore'.

Step 3. Follow the instructions on the wizard to get your system back on previous state.

Like password reset disc, you also need to create System Repair disc before Operating System disaster might occur. So, it is necessary for everyone to create a System Repair disc in case you need to boot from it to recover your OS.

Part 3: Reset Sony VAIO Password with Command Prompt

A command prompt is a command you issue to your computer using a built-in program. If you want to reset or change logon password, Microsoft Command Prompt would be a great idea for accessing to your Sony or other brands computer. On Sony VAIO laptop, you can also reset your login password from command prompt by signing into the PC with any other admin account.

Step 1. To open the Windows command line, type 'cmd' in 'Run' command box by pressing 'Windows Key+R' key combo. Hit 'Enter' to launch command prompt.

Step 2. Type in 'net user UserName NewPassword' command in the command prompt and press 'Enter'. To remove password, write * instead of NewPassword.

Warming: But I won't advise you to use command prompt to reset your password if you're not computer nerd, because you will face with high risk of damaging your system and losing your data. If anything bad should happen, don't say we didn't warn you! If you're a newbie, Part 4 would be the best choice for you!
