Thats exactly what you have to do i'm afraid.
Practice soldering first, there is no other way.

Open the memory cover and its just inside the edge of the plastic lip, the best bet is to use a shorter as shown on the site in my tag as it will make life easier if however you still can't find it, I have a pic and if you email me using the link on the site in my tag I will send it to you.

D3000 Help

Once I solder the jumper and power on the computer. Should I shut it off when the screen comes up, or should I go into BIOS and turn anything off?

For the C610 short the wires as it boots for about 3 seconds, if that doesnt work try shorting straight after power on.

The thing with the shorting method is to try and try, some people get it first time, with myself it was a combination of short during power on from 3 -7 seconds, then remove the PSU and short whilst rapidly pressing the power button about twenty times, there is no sure method only perserverance and persistence.

Good luck,

By the way some of you are still emailing Paragon for the files, I think Paragon is a bit ill at the present so if you need any of the files you can find them all on the site in my tag.

D300 Help

Should it be a black screen when i get the jumper or should it look like the normal dell boot screen. I soldered what should be 3 & 6, but all I get is a black screen. I tried 2 & 5 and it just boots to the password screen.

D300 no more help

I finally got it. I had to install a small rip cord to my soldered short. Once I turned on the computer I got a black screen. I pulled the rip cord broke my jumper and rebooted into manufacturer mode. This has been an experience that I would like to get. Dell Sucks.

Sorry I have been out of things for a while in the Hospital. The easiest way to ground the EEProm Chip on the Latitude CP, CPiD or CPiA and clear it, is to solder one wire only to pin # 6, reinstall the CPU/Integral Circuit Board, ground the other end of the wire to a grounded point on the board and then power on. After getting the Manufacturing Mode Screen, remove the CPU once more, cut the wire free with dikes, then reassemble the machine and run the DST Diskette to change and reset your original Service Tag

Hi
Its a case of perserverance, as I say to all its not a simple job, ask Paragon, he'll tell you that it can many many attempts to reset it.

Try shorting whilst powering on for a few seconds or longer, Try shorting whilst pressing the power button repeatedly (with the PSU and battery removed).

it really is a case of trial and error, make sure that you have a decent ground by using a test meter to test, if not move your earth elsewhere.

Huzzah!

Thanks Paragon! Your USB DST EXE file got me in. BTW this not only works for USB boot devices, but also for people that have a USB 2.5" HDD enclosure (much much simpler than cracking open your case and doing the Win98 floppy boot method). I was able to utilize this to get into my Dell Latitude CPi-A.

Inspiron 9100

Hey guys

I just bought an Inspiron 9100 off EBay and it has a password and of course the seller claims that he doesn't remember it. What is the best method for this? Should I try the paperclip method? I tried some of the password generators, but none of them worked. Also contacted Dell. Big surprise that that was no help Any help would be greatly appriciated! BTW - Is the paperclip method difficult, and what does it involve doing exactly? Thanks!

paper clip method involves you taking apart your lappy, or if ur lucky ull get the eeprom in the memory bay round the side somewhere.
its not hard to take ya lappy apart, its just fiddly and load sof little screws at diff lengths, but nothign too bad, i did my dell inspiron 510m yesterday with the help of this thread

any help u require just post here, the guys here are always willing to lend a hand

Inside the laptop is a small chip (yes its very small, about half the size of your little finger nail, and it has 8 legs,) the idea is to open the laptop, strip it down completley (the website in my tag will show you how to locate the service manual for your laptop) until you have access to the motherboard and then locate the CHIP it is marked with numbers, usually in the format 24cXXX, there is a picture of it on my website (see my tag), once found, dependant on location, you either short it with a shorter tool (paper clip or paragons tool) until the laptop resets to the manufacturing screen, at this point you press the function key on your keyboard plus the X key , or you attach wires to the legs and then short it. once shorted you have removed the SERVICE TAG and thus the passwords.

The shorting method vary's from shorting during power on to shorting with no PSU or battery and pressing the power button rapidly, there is no set method we have found that works with every Laptop.

Once you have reset the chip you will need to download the DST software from the site to set your service tag, as until you do you wont be able to set a password on the laptop (assuming you do, why not its yours protect it)

If you have any questions please ask, I usually drop in around tea time UK time.

How can I find the chip? I have removed most of the stuff to access my motherboard (Palm rest, Keyboard ETC) and now I don't know where to locate the chip at. Is it actually going to be on the bottom of the board or the top? If it's on the bottom like the one in the guide pictures, how do I remove the bottom of my case to get to that part of the mobo? Thanks!

Following the Service Manual to open your motherboard
http://support.dell.com/support/edoc...s/sm/index.htm

Locate your EEPROM. What I did is I used a camcorder and focused on all ICs with 8 legs and read its name. By doing that you could find the chip quickly.
After that, using the paperclip method to reset the laptop to manufacturing mode. And then using the software on http://homepage.ntlworld.com/judslat/paragon/ to clear the Service Tag and you done....
