HP / Dell / etc. laptop password help thread

Dell Lat 120L

Hi, read most of the stuff regarding this subject, and was wondering if the chip 24c04 in my machine is infact a newer or a derivative of the 24c02 talked about everywhere else ? If so any ideas of the pin numbers that require shorting ?

your laptop model cant be unlocked by hardware method(chip shorting)

The chip has 8 leads, can come in a variety of shapes and sizes. It is part of a larger family of serial storage chips
Which includes the 24LC02, 24C04, 24C06, and 24C16.

The last 2 numbers in the name refer to the number of Kilo-Bits that the chip can store

24C04 chips are in these Notebooks:

Latitude D505
Inspiron 510m
Inspiron XPS (C24O4N)

Dell Latitude 120L

Thanks for the feed back, I guess it's also present in this machine type too. Can this chip be shorted at start up ? Or does it need removing altogether ?

I posted a new thread on the forum and was told to rather do it here, so...

Need BIOS Master Password for Inspiron 1525, yes it's 595B (gray screen)
I searched the forums and I tried looking for the famous chip to reset, which that laptop doesnt have. It's a 595B so the generator doesn't work. A friend bought it and wanted me to fix it. In case you didnt figure it out we have no idea who the owner was so we cant get Dell to do it. Any one has any insight on this?

Right, so I saw that Paragon33 mentioned that some newer Inspirons can be reset by taking the CMOS battery out. I did that but now I dont know if I should put it back in or leave it off completely after the overnight wait? The later sounds crazy since no BIOS changes will be permanent.

The EEPROM chip seems to be a 25 series one with a huge load of pages of 256 bytes each and no reset capabilities. Any help would be appreciated.

Thank you,

Sword2

Hello sword2 i have the same problem with my inspiron 1525 but i have failed to locate the bios chip.please help me find it then i'll give u means to reset it or replace it if it can't be reset. mukasa

i confirm that neither 120L or inspiron 1525, had eeprom chip to short!, pay attention yo may damage you laptops

Hmm. Now that's good advice :grinthumb

I also note that OBI made comment on this Post about what can and can't be shorted (not sure if it's correct or not)
https://www.techspot.com/vb/post651742-105.html

But if you would like to put down all the model that cannot be shorted
And the user cannot use the Manufacture support
Then I only have one more advice for them, contact someone like you!!

So it would be in everyone's best interest to supply this list (I'd say especially yours)

Dell Latitude 120L

Thanks for the advice, so does it mean the only way forward is to replace the 24c04 chip ?

Hmm

Gents, again thanks for the feedback, and if the only way forward is as suggested by Samyloo, but if any other options are on the table I'd be interested to know .

sorry, but your list isn´t correct.
Many of your posted Inspiron models can be unlocked by shorting method.

If you can boot from anything, use DST software, if not, use paperclip procedure of Fastback68. It works fine and free on Latitude 120L.

Ok back to square one !

Anyone (ie OBI) got the real list? Or is that the one that I quoted above ?
And don't start an argument. It won't go down well with this thread presently (hint hint)

I don´t know what you tried and what your speciality is, but if you didn´t get it working, you did something wrong.

sorry, read previous posts above!, your D620 cant be unlocked by hardware method (shorting eeprom)

OK Boys,

With the help you all have given, I have done the Paper clip method and even though the Hard drive was also Password protected I got around that and am at this very minute reloading the C-disc with software items that I use.

With the latitude 610 it was not for the faint of heart project, it took somewhere in the area of 4 hours. I had to tear the mother board out of the case completely, Find the Chip. (it was a 24c02n by the way) and it was in a different spot then the c600 is. I took some pictures as I was doing it so I can post a pic of it's exact location on the board if anyone likes or wants. But if you remove the back cover that exposes the memory cards and remove the memory card #1 you can see it just hiding under the edge of the back case just out of reach.

I pulled all of the wires out of a wire coating except for "one" I then soldered that wire across the chip leaving about 3" to 4" left on each side of the chip actually leaving the wire as one piece at this time. Then I re-assembled the computer. I clipped the wire from the outside of the case to make it two individual wires. It took about ten or twelve tries to get it to start up in the Manufactures screen.. Once it was to the point I could start the computer to windows, I slipped the rubber "Sleeve" off the wire and pulling back and forth on each bare copper wire they both broke right at the Solder joint. So I did not have to dis-assemble the whole thing again.

I had already purchased a Password Bi-pass CD, and starting the computer from the CD drive I ran it and it removed the hard drive password which then the CD formatted the Hard drive and now I am starting out fresh.


Here's the back of the board and the chip in relationship.



Sorry for the Quality but my camera doesn't give good close ups.


This Picture will show you just how close the chip actually is to shorting without taking anything apart! If you don't care what the finished product looks like you could cit the section away with tin snips, But I prefer things to still look like it's supposed to.

Huh !

The other discussion just doesn't mount up better than that

Well done :grinthumb

By the way, Yes please attach the pics, by editing your Post, and then selecting Advanced Edit, and then attaching your pics.
If they are above the 200Kb limit in size, you can either try to reduce them (using a photoediting software package) Or upload them to here, and then copying the provided link(s) to a new post reply, possibly with some info. Which computer model, and what step you were at.

Edit:

Thanks You did upload the pics :grinthumb
