Latitude CPx
Hey guys, I'm was so glad when I found this forum. I thought, "Finally, a solution!" But, for some reason when I type in my service tag into latitude_MasterPW.exe it tells me that its an invalid input. I've done what you guys said and typed in the whole number, but it doesn't work for me. Somebody please help! My service tag is: #8UBNR**-D35B
Thanks

Type/enter 8BUNR**D35B That gives 2 possibilities, cigun16z and mie9a6i6vgonz01 said:Hey guys, I'm was so glad when I found this forum. I thought, "Finally, a solution!"

See if one of those will work
Dell Inspiron 3800 Admin Password Reset
I just wanted to say a couple things about "Latitude_MasterPW.exe".
1.) If your "Primary Password" is disabled enable it so that when you reboot you can get the whole "serial number" for your Laptop. (Do not put the leading # sign into the "Latitude_MasterPW.exe" program, put in everything else up to but not including the comma) I know this sounds funny about the "Primary Password" but on this Laptop only the "Admin password" was enabled. That means the "initial password protection screen" will not come up when you start your Laptop and that is where THE number is. So anyway when and if you enable the "admin password" then the "configure setup" option is viewable and comes up Disabled so that no one can make changes to your bios settings. You can't even change the date and time! If you disable "Admin Password" then "Configure Setup" is not viewable. Try it. A former employee set this for me and that's why I was stuck. No I wasn't going to call him he got fired.
2.) So in my case once I got the "initial password" screen up and had a new password from "Latitude_MasterPW.exe" I tried what I read and heard from Dell and thi post. Just pressing enter after typing the "new password" clears the "Master Password" but not the "Admin Password". I read the posts again and found one that said to press enter twice while holding down the Ctrl key. That didn't work. But what did work was to press Ctrl+enter and hold it down for a while. I'm thinking I held it until the boot process started and maybe even until the bios setup screen appeared. Then when you go to the security page the "Master Password" and the "Admin Password" options are disabled and there is no "configure setup" option. Cool, ty all.
3.) Just thought I'd add a 3rd thing. I did call dell and they gave me the same "default password" number as the "Latitude_MasterPW.exe" did. Between dell and you guys I can know set the date and time to the proper value. Where Dell support failed, in my case, was not to tell me to hold down the ctrl+enter key for a while. Of course this is just one BIOS in one Laptop in a world full of Laptops. My personal opinion is that if you need security
that bad to protect your computer just live with putting in a "master password" only. But opinions are like A HOs. Everybody has one.

Inspiron 1150 model PP08L
I have model PP08L and since I asked the question, I found the little bugger 24LC16B. I had to take apart the entire notebook to find it on the bottom of the MB! In order to jumper it and put it back together to apply power to it, I had to mark the location and then reassemble the notebook. Then I had to actually cut out about a 1/2" square in the bottom of my notebook in order to access the darn eeprom! I then used a paper clip to jumper the 3rd from the left on top and the 4th from the the left on the bottom. It did not work at first but I had my wife repeatedly cycle the power on and off and it suddenly began to boot into Win. XP! I used the computer for a while and then shut it down. I then tried to boot it and I found I was back to square one stuck on the admin. password screen again! How frustrating! What do I have to do, jumper it every time I want to use it? How can I make this permanent. I was actually going to go into setup when I restarted. Thanks for the quick response.

Hi Paragon,
I have a C840 that I have now found to have a 595B suffix to the service tag.
I cannot clear the admin password with MasterPW, so I have sent you a email to kindly request the software you have.
I too bought my laptop second hand, but know it not to have been stolen. It required a UXGA screen that was deemed too dear to replace - Obviously haven't heard of that wonderful place called ebay!
I am using it now with the new screen I replaced, but it is running Windows 2000. It is setup with a limited account. As I do not have an administrator password to use it to its fullest, I would like to install a fresh copy of XP on it.
Can't boot from CD without the Admin password though - HELP :knock:

Dell Password Problem
I have the same problem with a Dell Inspiron 8600. My service number ends with 858B so I'm assuming I will have to erase my eeprom. I was looking at the data sheet of the 24LC16B but it doesn't really say how to erase the eeprom. So what do you do once the eeprom is erased? You have to put something back into it. Please let me know how I should go about this. Thanks

D600
I am working on a co-worker's D600 that has a boot password on it as well. I cannot believe that there are so many people on this thread that have the same problem. The DOS password utilities don't seem to generate the correct master password for getting past the bios password and I am a bit hesitant to disassemble my co-worker's laptop to jumper the eeprom. Has anyone had any success with the other solutions?

Dell password
all your`s problems are stored in a eeprom24cXX (02,04....) atmel chip
read a chip with some eeprom reader and send me on email and i read your password for you
in eeprom are stored user pass master pass hdd pass (only if a hdd is lock in the same laptop) serial number and tag So you can change all this if you want DO NOT ERASE FILES IN THE EEPROM IF HDD IS A LOCK ON THE SAME LAPTOP
DO NOT CONNECT SOME PINS ON THE EEPROM ( I READ SOME SOLUTIONS FOM THIS FORUM) IF YOU ARE NOT SKILED (SOME SMART GUY BURN A VGA ON THE MOTHERBOARD (DELL D600) 2 DAY`S AGO) SO....
an this is a only good solution (solder and desolder a chip from motherboard)
for now for all dell notebook`s
this is it for now
sorry for my bad english

You are welcome to your opinion since this is an open forum, but if you remove the harddrive before starting the shorting technique, it works fine. The hardddrive is a lost cause of course, but you will have a laptop which will function normally with a new harddrive after using the software I use to reset the Service TAG. Far more motherboards are ruined by an amateur soldering on a new EEProm chip than with the shorting method. I have done a bit of soldering on double-sided boards, but that chip is one I will not try to replace.
I have lost count of the people who have contacted me on my Email for the files and then recontacted me later to report success.

I was successful in shorting the EEPROM and reseting the service tag. I can now enter BIOS and boot of the CD-ROM, however the system also has a hard disk password. I removed the hard drive when I was shorting the EEPROM. I take it from the above exchange the hard disk is a hopeless cause and a new one will have to be purchased. Is it possible to take out the hard disk and format it? I have a laptop to IDE and laptop to usb hard disk adapter, so I was wondering if I could clear the HD with this?

I do not know of any way to remove a Harddrive Password. I have an older drive here which I purposely set one on and tried many ways to clear without success, including the "debug" method espoused by one poster earlier in this thread. There are professionals who can do it, but the cost is prohibitive unless it is to recover needed files. Reformatting will not remove the Password and you will not be able to get the drive recognized as present in an external drive case.
Dell hdd password
Ok this solution is ok when your hdd is not locked but if hdd is lock on your dell and u do this kind of solution you will delete a same information about your pass for hdd because in atmel 24cxx are stored a information about master, user, hdd password, tag ....
but when u desolder eeprom an read his contents u will able to see a passwords but this contents are cripted and i cen read it for u want and tell u what kind password u hawe on your dell, this solution works only if your hdd is lock on the same computer (dell xxxx) but if you hdd is locked on a another laptop and put in the dell u cant do nothing about hdd pass
soldering a atmel 24cxxx it works on a dell hp compaq asus ibm(24RF08) siemens fujitsu acer in the toshiba older model u can use a dongle if u have a lpt port on the same computer or u can a use usb dongle for some toshiba models wihout lpt port but a new toshiba is a PROBLEM for now because password is stored on proccesor onboard (not CPU) or some kind a controler
this it
