    I already got the master password from someone else. It still isn't booting up. Its not seeing the hard drive or something. I'm gonna try to find a boot/diagnostic cd.

Hey

first of all, you have not been charged as far as I know, in the marketplace you only get charged if you accept the solution, or it should be automatically refunded after 7 days of inactivity.

The battery will not remove the password. As for not booting up, go to the bios and check that the hard drive is detected and that you have the boot order set properly so it starts from CD drive and then Hard drive.

If the hard drive is not visible in bios, it is most likely faulty, try another hard drive or test the old one on another computer.

naturally if you replace the hard drive there will not be any kind of recovery options available to you - you must install windows to the computer from a CD or a memory stick to get it to work again.

Important (Please read befor you proceed)
Whichever method you choose when flashing ,the BIOS not only the password, but also all the other configuration data will be reset to the factory defaults. So when you are booting for the first time after you have flashed the BIOS, you should enter the CMOS configuration menu and fix up some things. When you boot Windows, it may happen that it finds some new device, because of the new configuration of the BIOS, in this case you'll probably need the Windows installation CD because Windows may ask you for some external files.

WARNING!!! Make sure your computer is unplugged before removing the case. Ground yourself before handling any components inside a PC to reduce the risk of electrostatic discharge.
If you don't know how to configure your BIOS, don't mess with it. You can damage your PC!! Rather get a qualified technition to hep you.

There are a few ways to reset the BIOS password as listed below.

•Using a manufacturers backdoor password to access the BIOS.
•Use password cracking software.
•Removing the CMOS battery for at least 10 minutes.
•Using a professional service.

Standard BIOS backdoor passwords
The first and easiest way to bypass a BIOS password is to try one of these standard manufacturer's backdoor passwords:

AWARD BIOS
AWARD SW, AWARD_SW, Award SW, AWARD PW, _award, awkward, J64, j256, j262, j332, j322, 01322222, 589589, 589721, 595595, 598598, HLT, SER, SKY_FOX, aLLy, aLLY, Condo, CONCAT, TTPTHA, aPAf, KDD, ZBAAACA, ZAAADA, ZJAAADC, (eight blank spaces), ALFAROME, ALLY, ALLy, aLLY, aLLy, aPAf, award, AWARD?SW, AWKWARD, IOSTAR, CONDO, condo, d8on, djonet, J256, J262, j262, j322, j332, J64, LKWPETER, Lkwpeter, PINT, pint, SER, SKY_FOXSYXZ, SKY_FOX, syxz, SYXZ, TTPTHA, ZAAAADA, djonet, %????? ?p??????%, %?????? ?p??????%

AMI BIOS
AMI, A.M.I., AMI SW, AMI_SW, BIOS, PASSWORD, HEWITT RAND, Oder, AAAMMMII, AMI?SW, CONDO, LKWPETER, MI, PASSWORD.

Other passwords you may try (for AMI/AWARD or other BIOSes)
LKWPETER, lkwpeter, BIOSTAR, biostar, BIOSSTAR, biosstar, ALFAROME, Syxz, Wodj

Note: Remember that passwords are Case Sensitive. The last two passwords in the AWARD BIOS list are in Russian.

Phoenix Backdoor BIOS Passwords
BIOS, CMOS, phoenix, PHOENIX
Other Manufcaturers Backdoor Passwords: (manufacturer name - password)
VOBIS and IBM - merlin
Dell - Dell
Biostar - Biostar
Compaq - Compaq
Enox - xo11nE
Epox - central
Freetech - Posterie
IWill - iwill
Jetway - spooml
Packard Bell - bell9
QDI - QDI
Siemens - SKY_FOX
SOYO - SY_MB
TMC - BIGO
Toshiba - Toshiba

Flashing BIOS via cracking software
If you have access to the computer when it's turned on, you could try one of those programs that remove the password from the BIOS, by invalidating its memory.

!BIOS software
!BIOS has the ability to "brute force" the password (known as "blasters"). However, this method is dangerous and can result in some unexpected and unwanted results. I highly recomment trying out all other methods before tying this one.

Download !BIOS software and save it to your desktop. Then open a DOS command windows by going to Start > Run and type: cmd
Once you see a black screen in front of you, you will need to type: cd desktop
You should now see something like: C:\Documents and Settings\YourUserName\Desktop>
Now type the name of the file you just downloaded, if you haven't changed the name just type in: bios320.exe
I can't get past the bios password on my laptop. - slasher_x_44.jpg
Use the down arrow and choose "Crackers" and then press the right arrow. Using the up and down arrows, select the BIOS that the motherboard is using and press Enter.
You should now see a menu asking what you want to crack, in most cases its the Supervisor or System Passwords you want to crack, so press the 1 key on your keyboard. It will then show you another menu asking how you want it to be cracked. Option 1 is pretty good so try that first by pressing the 1 key on your keyboard. You should now have your BIOS password.
Reboot the computer, enter the BIOS and try it out.

However, it might happen you don't have one of those programs when you have access to the computer. You can reset the BIOS to its default values using the MS-DOS tool DEBUG (type DEBUG at the command prompt. Do it in pure MS-DOS mode, not from a MS-DOS shell window in Windows). Once you are in the debug environment enter the following commands:

AMI/AWARD BIOS
O 70 17
O 71 17
Q

PHOENIX BIOS
O 70 FF
O 71 17
Q

GENERIC
Invalidates CMOS RAM.
Should work on all AT motherboards
(XT motherboards don't have CMOS)
O 70 2E
O 71 FF
Q

Note: The first letter is a "O" not the number "0". The numbers which follow are two bytes in hex format.

Resetting BIOS via hardware (CMOS battery)
If you can't get into Windows and the standard backdoor passwords didn't work then you will need to flash the BIOS via the motherboard's hardware.

NOTE: Please read the important note at the begining of this section before to try any of these methods.

Removing the battery
If you can't find the jumper or if it doesn't exist, you can remove the battery that keeps the BIOS memory powered. It's a button-size battery somewhere on the motherboard

The laptop CMOS battery is shown below.
slasher_x_47.jpg
Disconnect it for 15-30 minutes or more, then reinsert it and the data in the BIOS memory should be reset. If at first it doesn't work, try to remove the battery overnight. Once the battery has been reinserted power up the PC and see if the reset was successful.

Please help cant get past bios password on a dell inspiron 1545 the code i get on the white screen and the code is 824S9L1-595B Please help me.


Did you try removing the CMOS Battery?

You'll have to remove the CMOS battery. Most laptops require you to take the laptop apart to get to the CMOS Battery. It will be a silver battery about the of a nickel on the motherboard. The most common is CR2032. Also sometimes the battery will be in a vinyl covering and have a cable that attaches to a port on the motherboard. Whichever type you have you'll need to either remove the battery or unplug the cable and let the laptop sit for an hour or two. Then put it back, reassemblethe laptop and reboot the laptop. With the CMOS battery out the computer will lose the date, time and password.

If removing the cmos batter does not remove the password you'll have to go to the manufacturers website and look for the manuals. See if the manual references how to reset bios. Most likely you'll have to short the jumpers or pull a pin.

Here is the data that I have found: In order to have the BIOS or hard disk password removed (This include any biometric security), the notebook will need to come in to our repair depot for password removal. This service is not covered by warranty and unfortunately there is no other recourse to remove a BIOS or HDD password from the notebook. The flat fee for BIOS password removal is $100.00 US dollars plus tax. If it is a BIOS or HDD password and you would like us to service it for you, please contact our telephone technical support line at 1-800-816-2237. Hours of operation are 7am-9pm CST Monday-Friday and 8am-5pm CST Saturday and Sunday, excluding holidays.

FORGOT BIOS PASSWORD DELL LATITUDE E6400 HELP ME PLEASE...!!! THX


The above solution does not work on an E6400. Any fix regarding removal of battery, shorting pins together, etc does not work. However, what does work is to use the Dell Asset/Service Tag BIOS Reset Tool that is available on Torrent Sites. Boot the CD image and when you are asked if you want to delete/change the service tag select "Y". When asked for the new service tag number re-enter your current service tag. Then the tools erases the BIOS and inputs the new service tag. A by-product of this process is that the BIOS master password is removed from the BIOS.

Dell latitude bios reset


The BIOS setup password is stored in NVRAM and can only be accessed with that password. On the bottom of the laptop there is a Service Tag number. Dell support site can use that number to generate a master password for you. http://support.dell.com/support/index.aspx?c=us&cs=19&l=en&s=dhs&~ck=mn If you need further help please post back.

NEED TO BREAK THE BIOS PASSWORD ON MY SON'S DELL INSPIRON 8500


Usually there is a jumper to clear the cmos which will reset the bios password should be near the battery.
There is 3 prongs the jumper is on 2 you need to move it to cover the one that the jumper is not on.
Either that if there is only the jumper just remove it and then reseat it.
