First of all I want to thank Paragon33 to have been here giving precious advices and good tools for so long,
Ididmyc600 to also have been here to answer to the questions of newcommers like me and having built up the magnific site
https://www.techspot.com/vb/topic90285.html on which we can learn a lot on BIOS, ways to reset it and tools to make it easier
and rustam_ for providing the hope of a password that make more and more people come to this forum to post their different configurations and way of solving their problem.
So for all people who have post on the forum and especially for you three a big THANK YOU, because after having read all the posts I could find on this forum, I ended on an other forum where a single word helped me to complete the process.
Now that the politeness duty is filled, I will explain where I was blocked so other can profit of my experiences and avoid to lose 20 hours like I did on this problem.
First of all the PC I just bought in a market is a Dell Laptop D600 on which was enabled the Primary Password
I tried the utility named Latitude MasterPassword, but like I saw later due to the end of the Service TAG (595B) this utility couldn't work.
And like always in this situation, the boot sequence was configured to not accept CD or DVD, and like this model doesn't have a floppy drive, I couldn't use any utility or boot cd.
So I turned to the shorting methode.
The first difficulty was to found the chip. I finally found it crossing a video on youtube (that shows an unsettled laptop and the chip concerned) and the advices from this forum.
Then I scrupulously followed the global method that I built from different parts of sites, pdf and threads, but it wasn't effective.
After a lot of reading, of tests and sweat, I founded a forum that says simply:
Step 1. press power.
Step 2. short wires 2 seconds.
Step 3. disconnect wires, wait 2 seconds.
Step 4. short wires again for 2 seconds,
Step 5. disconnect and wait for "Maintenance Mode" text.
Step 6. Hit F2
Step 7. Hit ESC, Choose save and exit
Step 8. Enjoy your unlocked Laptop (with NO service Tag)
At this time I included the notion of order in my global comprehension of the method.
So I took my paperclip, connected the pins 3 and 6, pressed the power button, disconnect and quickly reconnect the pins to make the laptop start, wait 2 sec and before the beginning of loading, disconnect.
At this point, I finnaly leaved my great companion the paperclip, and made the danse of the victory before my laptop that was waiting for a Fn-X in the manufacturing mode.
So I finished the operation with the cd provided by Paragon33 and I have now an useful computer.
So once again thank you.
PS : excuse my english, I'm french
