Dell BIOS Password Removal

You must get the Manufacturing Mode Screen before running the software; and it must persist. A momentary flash of that screen, or even if it hangs on for 15 seconds or so is not sufficient;it means the eeprom is not cleared beyond the "point of now return". Once you get there, the paper clip is not held in position any longer. I got 5 of these false positive results just like you are getting on the 1150 board, but I hit it right on the 6th try and it cleared to the MM Screen. You now know what I meant with 'later models trying your patience and persistence".

Thanks Paragon. I'm assuming when you say Manufacturing Mode Screen, you mean the screen that says to Hit FN+X? Here is where I'm a little confused because I've only seen this screen come up a handful of times. Most of the time when turning on the laptop and shorting the clip, it just goes straight to the boot device. If I hit F2, it goes into the BIOS. Is there a trick to getting this Mode to come up? Thanks for all your help!

Thanks Paragon. I'll be working on this in the near future.

Hey guys, without reading every page of this thread, is this thread mainly for Dell LAPTOP BIOS passwords?
Because I've got a Dell Dimension 2400 desktop with a "Setup Password", which does not erase when the BIOS is reset.

Does this thread cover that situation? Or can you tell me the quick fix?

Hello friends.

I have read all 22 pages so far of this thread But I couldn't find any info about a Dell Inspiron 4000. I think that the solution is to use the paper clip and then the software given by Paragon33. But my problem is that I can't find this chip in my laptop. Anybody knows where is located? and if I have to uncover only a small part of the laptop or open it completely?

Sorry for my bad english

Thanks in advance

Hay paragon33 could you send me the files to unlock my dell D610 thank you in advanced... email removed :confused:

Malcolm, I got your email, but have been busy with other matters today. I am getting ready to send the files out to you and three others in a short time. The C600 and Inspiron 4000 are hardware clones. There are 2 pictures in the Additions file with the chip location on the bottom side and the hole I cut in the aluminum sheathing(after removing it from the board, cutting the hole and then putting it back)

Hey Paragon any tips on getting to manufacturing mode? I just can't seem to get that screen to come up anymore. I got it to come up maybe 2 times but wasn't fast enough to hit FN-X before the screen disappeared. I was thinking is it a different pin short combo to get this to come up as maybe I was accidentally shorting different pins since thats easy to do? Thanks man!

I used 4/6 pins. Another user fed back that he was successful with 4/5 pins. The 4 pin is the VSS (ground) on the 24LC16B chip; pins 1, 2, and 3 are not connected internally

FINALLY! It was that manufacturing mode that did the trick. Had to short pins 3 and 8 to get it to come up. Thanks again Paragon for all your help!

MOTHER!! Defeated the System password, now I'm met with a hard drive password. Its a Hitachi. Oh well at least the laptop is now usable. I'll just have to buy another hard drive.

Paragon33 thank you for the files I got it them on my email , I got the lap top open but unable to locate the chip on dell D610 please I need advice on chip number and where to locate it I been looking on the file you send me but only shows model D600 and I don't see the chip # on my model..... :( :(

Remove the PCMCIA Hardware and lift the rubber insulatig sheet. Remove the PCMCIA Hardware and lift the rubber insulating sheet. I believe you wiil find it there; several types have been reported, but the D610s' chips all have 24 in the type number, are 3mmx4mm and have 8 connections. Pins 4/6 and 4/5 seem to work the best

Thank you very very much bro for the fast respond you are the bomb :D :D

Hey guys I got the pci card remove but I don't see the chip yes there are 4 chips each one with 8 pins 2 had the same part# P46AB, other PF1DR,other 12N003L the question is can I try all 4 with out damage the laptop,, thank you in advanced ,,, :confused: :confused:

NO-O-O! Using the wrong chip as target can ruin your board. If it is not there, it may be on the bottom of the board and under a metal brace

paragon33 thank you for you help but I think F*&*"?> up I got desperate last night and I jump 2 of the chips I mention on my last post now the fan does not turn on and the laptop does not turn on well it does turn but it turns off rigth way now what is next please help.... puke: puke: puke:

Get another board; that one is labeled R.I.P. Patience is virtue, particularly where laptops are the subject. I warned you most emphatically not to do that. You are the second person to fry a motherboard by shorting the wrong chip

Hi everyone, First: Thanks to Paragon33 who kindly send me the docs and software for overriding the bios password.
Now, I tried this: short pins 3 and 6 of the chip and then press on, so the laptop doesnt turn on, it keeps turned off and nothing happens.
Tried to press on button and then shortcut pins 3 and 6 od the chip, but nothing.
Does anybody have succed with a Latitude c610? help me please!
PD. Paragon33: what a great guy who shares his knowledge without asking anything!

Hey there I have a dell Latitude D510. havnt been able to find a way to get pass the ADMIN password. I was going to do a transfer of ownership but I was hoping that someone could tell me what All information they are going to ask for when I call because the amount of INFO I know is limited.

Thanks in advance
Tony :cool:

Tony :cool:
The first thing they are going to ask for is the previous registered Dell owners' name(s) and they do not mean the person or dealer you bought it from necessarily, as they may have gotten it used and resold it. If you do not have that info, do not waste your time on the phone, as they will not help you. If you want to try online, this link is to the online forms
http://support.dell.com/support/topics/global.aspx/support/change_order/en/tag_transfer
There is also an International form

Could you please help me?

Sorry for my English.

Hey Guys if you have a Dell LATITUDE D610 that has a bios password, and you don't know where the EEProm Chip is let tell you that is on the botton part of the motherboard close from the spekers outputs. but if that din't made sence for you the chip number must say 24LCO4Bi. I also have a picture that shows where the chip is at. If you want it.

Another thing is that i want to say thanks to Paragon33 who send me the guide of how to erase the bios password and files to make a service tag for my computer.

sorry for the grammar english is my second language.

si Necesitas ayuda en espaņol te puedo ayudar ok. es gratis

You have been eating too much fermented applesauce. That will have exactly zip for help on a Dell. Why don't you read back through this thread, as this recommendation has been shot down a number of times before?

Tadaa

Finally I have disabled the password - thanks to Paragon33 and his great guide.

I have found the EEPROM chip on the backside of the motherboard behind the PCMCIA slots.

If anyone of you will need help with his Latitude XPi or similar I will help with pleasure.

Paragon33 - youa are doing great job here :)

LOL!! Right on Paragon! I love it when people just come in here and assume this is some simple procedure and just blab out some ridiculous answer, having no clue what they are even talking about...

you obviousley havent worked on pc hardware just by your stupid attitude
rendering insults at people i would asume you are 8yrs old or maybe 6
i guesss what your saying is with me fixing on average 40 computers a week i got no clue right on man have nice day and keep taking drugs !!! :hotbounce

On the contrary, I am 75, you juvenile motormouth, and I have done my share of Dell laptops. I wish you could show me any gutter mouthing that has been done besides yours.

i do not have an admin. password problem its the password to logon to windows. how do i get by this?

Paragon, sent you an e-mail.
I'd be delighted if you could send me the details for the Dell bios password removal at your convenience.

I have a customers 4th or 5th hand Dell D800 and don't fancy trying to update the ownership via Dell. They're not too customer friendly at the best of times!

Do you have a Paypal account I could make a donation to ?

I have built a circuit and read the data directly from the 24c02 chip on my inspiron 8000 Now I need to get the password from it. does anybody here know of a program that will convert hex to plain text?
. If anybody else wants to try to read the chip it is fairly easy just takes a 2 resistor 2 diode circut(2$ worth of parts at radio shack) and a free program called pony prog
here is the chip dump if any might be interested in taking a crack at it

SUCCESS!!!!!! My expensive paperweight is a usefull computer again!! Thanks to all who posted here and some other sites The shorting trick worked after about the 15th time (4&6 pin) All of you have been a big help! anyone needing help with an inspiron 8000 let me know Ill do my best to help :bounce:

This thread has helped me out allot. Thx.

Hi All!

Just to confirm that it's totally possible to reset the BIOS administrator password on the Dell Inspiron 8500 using the aforementioned paperclip trick.

If you are looking for the security chip on the 8500 it's located on the top of the motherboard about 5cm in from the headphone socket on the right of the laptop directly under the hard-drive caddy cage (you won't see the chip immediately, it's underneath a plastic insulating sheet).

You are going to need to unscrew the keyboard and remove the upper plastic casing which sourrounds the touchpad etc. Then remove the hard drive caddy (remove one screw and it'll slide out with encouragement). It can be a bit of a fiddly job and you'll probably end up unscrewing things you needn't of, but have patience and make a note of what screw came out of whch hole unless you've done this sort of thing before.

MAKE ABSOLUTELY SURE YOU'VE GOT THE RIGHT CHIP - you really won't get a second chance at this if you guess and get it wrong - shorting the wrong chip will result in one totally dead and deep fried mobo.

It took me about 15-20 attempts to short the security chip properly and blank it's contents. Sometimes the board wouldn't boot at all with the paperclip making contact so I had to remove it, waited until the Dell splash screen appeared and then started shorting the connectors. Some people seem to find success in removing the paperclip just before the 'administator password' screen pops up, but I just kept that sucker on there until it gave in and wiped itself.

Just for the record I didn't actually reach any sort of 'manufacturing mode'. I just suddenly got a standard bios type message screen stating that no bootable drives were found (because the HDD was disconnected) and then upon reboot it had cleared the password (which I double checked by entering the BIOS setup).

Fortunately for me the bios password had only been enforced on bootup and they hadn't locked the HDD down too! (which is good - that would of been a waste of 60Gb!!!)

The key is.. don't give up! Persistance is the watch word here. It probably won't work first time but stick at it - this method DOES work providing you do a bit of research and take your time.

I'd just like to thank all the useful contributors to this thread. I read it from start to finish yesterday and it took me about 2 hours last night to unlock the laptop (and thats only because it took me a little time to get the laptop stripped down and locate the security chip).

Thanks guys, hope you all have similar success. :)

I think I need a bit of help as I caun't get passed the BIOS admin password. I have a Latitude c640 (HT24LC04) and have tryed every single combination for jumping the pins (4/5,4/6), waiting 4-7 seconds before applying the clip, pressing the power button multiple times, nothing works.

The best i've got is the HS fan starting up while applying the clip then the screen going grey untill it finally shuts down.

I've been at this 2 hours solid with this damn paperclip and I swear if I see another one i'm going to flip.

I'm glad I only build Tower PCs for a living.

Hi Mate!,

Don't dispare, you will get there if you stick with it.

Lets assume you are looking at the security chip so that the writing on it reads left-right and isn't upside-down. The pins you want to target are the set which are the second in from the left. I tried other combinations of pins but these two were the magic set.

In my limited experience you want to be shorting these out as soon as you've powered the laptop up. The aim of the game is to get enough juice flowing through it long enough to wipe it's contents.

Keep at it - you'll succeed eventually!!

Paragon, many thanks for your documentation and help so far.

I still can't reset the bios admin password on a Dell Latitude D800.

Tried for a couple of hours, different timing before I disconnected but still can't clear it.

Anyone succeeded with a D800 ? Or am I just not persisting enough?

hi Paragon33 thanks alot for the quick reply and i sent amasseg for u at your e-mail i wonder why you didnt receive it
my email is (is_email removed)

how to do to get an 610er running : open the laptop underside!! ca.4cm under the small Battery ,and under a Framepart you see the EEPROM is very difficult to find it is an 24lc04bi .

It has 8 pins the first 3 are not delaeted pin 4 is ground, you must shortcut pin 4 with pin 6.

First start the Computer, then when you have to tip in the password do the shortcut, when you shortcut the right one pins(4 and 6) the ventilator starts to run , hold the shortcut until the monitor show you, you are ready.

The HDD was stil in by the shortcut , and stil works fine , bevor I found out the right pins (4 and 6) I nearly shortcut everypin with the other. everything runs fine . excuse for bad english i´m still german

thanks alot Paragon33 i opend the bios but i dont know how to open the hard disk password pleas if u can to explane the way how to do it
thanks agian

Hi all ,
I would like to offer my sincerest thanks to all those in the group for the info needed to unlock a newly acquired Latitude C600, it took a few tries with master password,exe before realising that my service tag was of the wrong type for the software, in the end it was a strip and hard reset of the board that finally cured it and now I am busy typing away on it sending this note of thanks.

So to all those who still have laptops locked, i did it and with a little effort the right info and the service manual you to can unlock your laptop.

Now all I need to do is reset my Service Tag so I can set a password, wheres that chap with the bootdisk?

Cheers and good luck
