Well if you have used the bios password that appears some seconds when you power on you laptop in a black or blue screen...you will need to flash the bios but internally in the motherboard so if this is your case, I recommend you go to a professional or send it to the manufacturer because it is very difficult to do by your self...

Once I change bios password, how do i use it to change password at start up/user screen? Fujitsu lifebook model b6220 (windows installed).


Bios password is completely separate to windows password. The BIOS is Basic Input Output System and runs when you first switch the laptop on, performing a POST operation. Once the POST is finished, windows starts loading up from disk.

If you need to reset a windows password, for example if you have forgotten it, then you need to use a bootable Linux password reset utility. There is a free password reset utility which is part of the ultimate boot cd and can be downloaded as an iso file and burned to cd on a separate computer. Once the CD is created, put it into your laptop and boot up the system. Use the menus to choose under file utilities, Offline NT Password Tool and it will allow you to reset the password of whichever account you choose

Can't reset windows 7 logon password as error


try this :
  1. Download the Reset Windows Password utility onto an alternative computer. Unzip the download file, you'll get the ResetWindowsPwd.iso file. Burn the ISO file to CD using an CD burning software such as ISO2Disc orBurnCDCC.
  2. Set your Windows 7 laptop to boot from the Live CD. To boot from the CD-ROM drive, you may need to press a key such as F8 or F12 while your computer is starting up and set CD/DVD as the first boot device in BIOS.
  3. After the CD boots, you will have a mini operating system loaded into memory which will launch Reset Windows Password utility. It will not install anything to your hard drive.
  4. Click on the Reset Windows Local Admin/User Password option, the program will automatically detect the Windows SAM registry hive and local user accounts existing in your local computer.
  5. Choose the administrator account and click on Reset Password button, it will remove your forgotten Windows 7 administrator password in a short time.

If you are confident at removing the cover, do so. There are four memory chips on the motherboard, next to each other. To the right are two triangles with a small C1 printed next to them. Short out these by connecting them with a wire, and press the power button. This should reset the CMOS.

Well, I am providing you four tips which you can consider to recover Windows administrator password if your forgot or lost it:

TIP 1 - Use password reset disk

Windows-based system was designed to be able to create windows password reset disk without any other third party tools. So you can make use of a password reset disk to reset your Windows password in case you lose or forget your Windows password.

TIP 2 - Restore the operating system

Windows password recovery can be performed by restoring the operating system. Since restoration leads to data deletion, the solution can only work if you have a clean and updated backup of your hard drive data stored somewhere else.

TIP 3 - Use Windows Boot disk

The boot CD for Windows can be used to reset the administrator password. This disk enables you to repair Windows OS, thereby, setting your administrator password as blank.

TIP 4 - Use password recovery software

This is considered as the best windows password recovery solution, however, is to download a third party software. These tools enable you to reset Windows administrator password without posing any threat to your hard drive data. Among so many password recovery software, windows Password Recovery 6.0 is an easy-to-employ application which can be used to reset lost or forgotten password of any Windows system. Now execute the following steps to recover your lost windows password if you haven't prepared anything.

Step1: Login to a computer that can link to Internet. Download Windows Password Recovery from

http://www.recoverlostpassword.com/products/windowspasswordrecoery.html and install it on that PC.

Note that: there is an .ISO file. Burn the .ISO file to a CD/DVD or a USB flash drive

Step2: Get out the newly created CD/USB and insert it to the locked computer.

Step3: re-booted the locked computer (it's necessary for you to change your computer's Setup to make it boot from CD drive or USB drive) and then followed the process of instructions. Just a few steps, the old passwords were removed.

Step4: logon PC without password and setting the new password

Reset bios without running hard disk first


2 options:

  1. create a bootable cd with the bios rom file, and a dos based flash utility (included with bios download). Boot to cd and flash.
  2. Connect a usb floppy drive and create bootable floppy. Copy rom file and flash utility to floppy, boot to floppy and flash......option 2 may be easier if you are not familiar with creating bootable cd's.......Let me know if this helps or not.

BIOS Update Procedure


BIOS Update Procedure
All latest Motherboards today, 486/ Pentium / Pentium Pro etc.,ensure that upgrades are easily obtained by incorporating the system BIOS in a FLASH Memory component. With FLASH BIOS, there is no need to replace an EPROM component. Once downloaded, the upgrade utility fits on a floppy disc allowing the user to save, verify and update the system BIOS. A hard drive or a network drive can also be used to run the newer upgrade utilities. However, memory managers can not be installed while upgrading.
Most pre-Pentium motherboards do not have a Flash BIOS. The following instructions therefore do not apply to these boards. If your motherboard does not have a Flash BIOS (EEPROM) you will need to use an EPROM programmer to re-program the BIOS chip. See your dealer for more information about this.
Please read the following instructions in full before starting a Flash BIOS upgrade: A. Create a Bootable Floppy (in DOS)
•With a non-formatted disk, type the following:
format a:/s
•If using a formatted disk, type:
sys a:
This procedure will ensure a clean boot when you are flashing the new BIOS.
B. Download the BIOS file
•Download the correct BIOS file by clicking on the file name of the BIOS file you wish to download.
•Save the BIOS file and the Flash Utility file in the boot disk you have created. Unzip the BIOS file and the flash utility file. If you don't have an "unzip" utility, download the WinZip for Windows 95 shareware/ evaluation copy for that one time use from _www.winzip.com or _www.pkware.com. Most CD ROMs found in computer magazines, have a shareware version of WinZip on them.
•You should have extracted two files:
Flash BIOS utility eg: flash7265.exe (for example)
BIOS eg: 6152J900.bin (example)
Use the latest flash utility available unless otherwise specified (either on the BIOS update page or in the archive file). This information is usually provided.
C. Upgrade the System BIOS
During boot up, write down the old BIOS version because you will need to use it for the BIOS backup file name.
Place the bootable floppy disk containing the BIOS file and the Flash Utility in drive a, and reboot the system in MS-DOS, preferably Version 6.22
•At the A:> prompt, type the corresponding Flash BIOS utility and the BIOS file with its extension.
For example:
flash625 615j900.bin
•From the Flash Memory Writer menu, select "Y" to "Do you want to save BIOS?" if you want to save (back up) your current BIOS (strongly recommended), then type the name of your current BIOS and its extension after FILE NAME TO SAVE: eg: a:13J900.bin
Alternatively select "N" if you don't want to save your current BIOS. Beware, though, that you won't be able to recover from a possible failure.
•Select "Y" to "Are you sure to program?"
•Wait until it displays "Message: Power Off or Reset the system"
Once the BIOS has been successfully loaded, remove the floppy disk and reboot the system. If you write to BIOS but cannot complete the procedure, do not switch off, because the computer will not be able to boo, and you will not be given another chance to flash. In this case leave your system on until you resolve the problem (flashing BIOS with old file is a possible solution, provided you've made a backup before)
Make sure the new BIOS version has been loaded properly by taking note of the BIOS identifier as the system is rebooting.
For AMI BIOS Once the BIOS has been successfully loaded, remove the floppy disk and reboot the system holding the "END" key prior to power on until you enter CMOS setup. If you do not do this the first time booting up after upgrading the BIOS, the system will hang.
BIOS Update Tips note: 1.Make sure never to turn off or reset your computer during the flash process. This will corrupt the BIOS data. We also recommend that you make a copy of your current BIOS on the bootable floppy so you can reflash it if you need to. (This option is not available when flashing an AMI BIOS).
2. If you have problems installing your new BIOS please check the following:
Have you done a clean boot? In other words, did you follow the above procedure for making a bootable floppy? This ensures that when booting from "A" there are no device drivers on the diskette. Failing to do a clean boot is the most common cause for getting a "Memory Insufficient" error message when attempting to flash a BIOS.
If you have not used a bootable floppy, insure a clean boot either by
a) pressing F5 during bootup
b) by removing all device drivers on the CONFIG.SYS including the HIMEM.SYS. Do this by using the EDIT command.
Have you booted up under DOS? Booting in Windows is another common cause for getting a "Memory Insufficient" error message when attempting to flash a BIOS. Make sure to boot up to DOS with a minimum set of drivers. Important: Booting in DOS does not mean selecting "Restart computer in MS-DOS Mode" from Windows98/95 shutdown menu or going to Prompt mode in WindowsNT, but rather following the above procedure (format a: /s and rebooting from a:).
Have you entered the full file name of the flash utility and the BIOS plus its extension? Do not forget that often you will need to add a drive letter (a:) before flashing the BIOS. Example: when asked for file name of new BIOS file which is on your floppy disk, in case you're working from c: your will need to type a:15j900.bin, rather than 615j900.bin only.
