Please help

Hello, I am a long time reader, first time poster. I have a dell inspiron 700m notebook and the service tag is "986XS51" I have tried everything I know possible. I have read the thread very thoroughly trying different methods. When powering on the laptop, I am immediately asked for a password. Once entered incorrectly three times, the laptop then askes for a master pasword. When entered incorrectly, the laptop shuts down.

I am assuming that this is a bios protection password, since I cannot enter the bios without the password. I have dis-assembled the laptop to remove the CMOS battery and also look for the "24 whatever" chip to short the pins. I do not see the chip.

I would greatly appreciate any help that can be offered. Thankx

(I have tried to contact Dell, unfortunately they would not help)

Laptop Bios Passwords

I just removed a BIOS password on an Inspiron 1100 it costs about $115 for the security chip which has to be soldered on the motherboard, then another hard drive since the previous one had a password on it as well! You will have to take the laptop apart and remove the security chip then solder on the new one (which costs $59 + $10 shipping from [COLOR="Red"]site removed[/COLOR]) put it back together and check to see if the hard drive was locked as well if so you can send the original chip to pwcrack and they will crack the password then you can unlock the hardrive which is $50 more or do what I did and get a new hard drive for $45 with double the capacity! Install windows and you got a working laptop! This was the only way I could get past this! You can call dell and they will generate a password for you using your service tag but you have to be or know the registered owner for the Laptop!

Hmmmm......

Have you tried this method? The only reason I did not go with this is because the Inspiron 1100 was not listed as a tested model. Exactly how does this method work, by shorting some pins for a few seconds or does the paperclip bypass the chip? How is this done?

Dell laptop Password removal

If you remove the Service TAG on Dell Laptops, it erases the EEProm Chip, and the passwords stored there are erased with the TAG. Then the same Service Tag is reset on the erased chip, but the passwords are gone. Unfortunately, the software to do this is kept from most users, or even the knowledge it exists or how to use it. I have a copy on a Diskette that works with Latitudes and SOME Inspirons. Other Inspirons that are clones of Latitude Models can be temporarily ForceFlashed with the Latitude BIOS by using a /jabil switch, the Service Tag deleted and then reset with this software, and then ForceFlashed back to the Inspiron BIOS.
The BIOS Primary Passwords can be cleared without changing the EEProm chip by shorting 2 pins on the chip with a piece of stiff wire or a small paper clip, and then punching the power button repeatedly. When you do this, the laptop board is set back to Manufacturing Mode FF; you then use the diskette to reset the Service Tag and the board is back to normal, but the passwords are gone. The chip is a small 8-connection chip labeled 24C02 or a variation on that label. It is found on the motherboards in many locations; on some early models like the CP/CPiD/CPiA series, it is found under the CPU. That makes the shorting trick difficult on those, but not impossible. It will require spot soldering two small, thin insulated wires to the proper pins, then bringing them out side the CPU recess, and installing the CPU again. The 2 pins to short are 3 and 6; as you view the chip with the label upright, the pins across the top are 5-8 from right to left and the bottom 1-4 from left to right, with 3 and 6 directly across from each other.
How do I know this works? Because I have done this several times, one of which is the original posters CS model. Before someone asks me about Harddrive Passwords, I have no solution for those, except don't use them on a Dell, unless you want to replace both M'board and Harddrive if you forget them. Bon Chance!

Latitude.EXE and Latitude Master_PW

Mr. Plain Key,
Those applications only work with the old -35B Passwords. The Latitude CP was the last model to use those and that was changed to the 595B Passwords by BIOS Flash very early in its life

Service Tag

Yes, I have done that shorting procedure and it works, but it leaves the board in Manufacturing Mode, and Asset.com will not always reset the Service Tag to return the board to normal. This software I have has done so every time; also, for clearing BIOS Admin Passwords on the Dells, just using it to delete and then reset the same password will clear those, which is far easier than disassembling the laptop to access the EEProm chip. I also have a Dell CD for Dell Techs only that has the same Service Tag Utility on it, along with a bunch of different BIOS flash Files.
I just finished doing an Inspiron 8100 board for a friend of mine. First I shorted the 24C02 Chip to clear the Primary BIOS Password, then Force Flashed the BIOS to the Latitude C810 version, restored the Service Tag using that utility, and then Force Flashed the BIOS back to the Inspiron 8100 version. The passwords are gone and the board is operating normally

I have a Dell C600, and none of the files Latitude.exe or the Latitude MasterPW.exe file work. I did try the process with the Debug file and I was able to clear the PW on the hard drive. I need to change the Admin Password or disable it so that I may continue to work on this computer and get it working again. The Service Tag on my notebook is D0LYG01. The BIOS revision is A03. I also checked for the chip itself, and it is not located under the ram, I guess I would have to tear it down completely. Any help would be appreciated. Feel free to drop me an email with any additional help!

The diskette I have will delete and then reset the same Service Tag. It will also remove an Admin Password- and also the Primary Password if you can get through the "grey screen" on initial boot. It does this by wiping the EEprom Chip, and then resetting the same Service Tag, but the passwords are gone.The diskette also has the Master PW file, but that was to get through the grey screen only on the older D35B passwords, and will only work on those.
To get through the grey screen on the 595B passwords, you need to short the EEProm chip to clear it back to Manufacturing Mode. For the Admin Password only, all you need is the diskette and no shorting is necessary

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
I purchased a Dell Latitude C600/C500 model PP01L at the Salvation Army's outlet store.
I can not access any drives (CD, Hard-drive, floppy-drive) nor can I access CMOS-Setup. I simply receive a Message: "" This computer system, # 52WJP01-595B, s protected by a password authentication system. You cannot access the data on this computer without the correct password.
Please type in the primary or administrator password and press <Enter> ""
I noticed that in the website postings mentioned latitude.exe (password generator file/program) which I tried but is geared to only receiving 5 (five) character for the Service_Tag_#. I also noticed mention of Latitude_MasterPW.exe as being able to generate a Latitude password in response receiving the Service_Tag_# as an input instruction but I have not seen that anywhere for downloading. Where can Latitude_MasterPW.exe (password generator file) be downloaded and does anyone know if it would solve my problem and work for my model (C600/C500) Latitude?
Any help would be appreciated.
My Dell is a: Latitude C600/C500 model PP01L
Computer system: # 52WJP01-595B
Service Tag #: 52WJP01
Express Service Code: 13054894417

does anybody know if this will work with a latitude d600? I need help I bought the system off some crackhead guy and i'm sure he probably didnt acquire it legally, but I've let the police know and if they figure out who it belongs to they can come get it, until then its mine, but thats besides the point, point is its useless until i can get past that dang grey screen

This is very recent since I posted the original on the Techspots. Dell changed the EEProm Chip sometime after the Latitude C840/Inspiron 8200 clones from a 24C02 to a 24LC16B chip and the shorting trick does not work on it. It will get you through the grey screen, but it does not clear the chip to Manufacturing Mode FF and the software will not reset the Service Tag( although it says it has) After a reboot or two, back comes the grey screen again; I did this 5 times last night on an Inspiron 1150 with the same results. The software I have will not help you with this chip on the board. Sorry.
UPDATE!!
Since I originally posted this, I have found that this 24LC16B chip had to be shorted using a different set of Pins (4 & 6) instead of 3 & 6. It cleared as readily as the others I have done and the laptop was returned to the sender who was pleased with the results

I too am at a lost. All that I have read doesn't seem to apply to my Inspiron 7000. I need a master password to access the laptop. I'm not seeing any service tag like db35 or whatever. Only thing i can see on boot is D300LT Bios Rev A15, and on Bottom Service tag H4639.
Any help would be great.
Thanks
Brian

latitude d600

I just bought this dell latitude d600 off of ebay. It has an admin pw set in the cmos and doesn't respond to latitude.exe or the master version. The service tag is 8MNZF51 with express service code 18843584869. It has niether a cd nor floppy drive so the debug method isn't an option atm. Is there any thing else I can do because I'd rather not crack it open and start possibly messing somethin' up.
