Stuck w/o BIOS password.v.EBay

Yes, that is the general principle.

Obviously you have to re-assemble to a point where you can boot the machine, so it depends on where the eeprom chip is located, as to whether you need to solder wires to it.

With some models it is quite readily accessible so it is safer to use a bent paper clip.

Try altering the case of the pass, also try holding down the control key before you hit enter.

Before you try that though, remove the hard-drive and see if you get the same error.
If NOT, then it is a Hard-drive password and not a system password. This fix is for a system BIOS password only. A new Hard-drive should fix it if it boots w/o the hard-drive or is cleared of a system BIOS password.
The chip is below the processor so you have to solder two very small wires and bring them outside the laptop then reinstall the processor.

Maestr0, Hello! It was a good explanation you had point out above. The Laptop that I am currently checking is Dell Latitude D505, does it fall in the CP or CPI category? And I had checked all around the board, even under the CPU but the chip seems to be not there. The owner had agreed with my suggestion to bring it to a Technical Shop near my place and have them examine it. The owner actually tried some shop but haven't solved the problem. We will try with the expert if they can really solve it in their side. (for sure they will not tell how they fixed it after they did it).

And BTW, I also tried removing the Hard-drive but it is the same story, so it is really a system password (forgotten by the wife).

I will still try your recommendations one last time with the MASTER PW (Latitude.exe).



I'll update you all with any of the above if what ever results will come.

Thank you!

Hi GONE~

Bad news I am afraid, if your service code ends with -595B it seems that the generators cannot find a pass for you.

Also, as the wife changed the thing, this will have overidden the default. I know that Dell Engineers have "God" passwords, but unfortunately I only "don't have them" for earlier models

I guess we have reached soldering iron/paperclip time. What you have to find out is where that eeprom chip is............it will have 8 legs (4x4) and should be printed up as a 24C02 or 24C04..... I think that the 04 is the most likely.

Good luck mate

nihil,

Thanks again! Actually, the technical guy from the shop also recommends to directly coordinate with Dell about the matter. Not much to do right now. I also suggested further to the owner to directly contact Dell here in the region as well.

And to the OP, DIXLEX, sorry for coming too wide about my own scenario of the problem in this thread, just update us of what happened with your issue.

Thanks again!
