  1. I need to know the location of the password chip on the motherboard of a Dell Latitude C840. Everything I have tried so far has not worked. I would greatly appreciate any help I can get on this.

    Thanks for the tip. I am getting closer but I still have to find the location of this chip on the Inspiron 8200. Thanks again!

    Here's another option (I didn't read that thread..)

    I don't know about the really new Dell laptops, but they used to have a USB dongle which could clear passwords. I believe this device will work for the 8200, as that's about the right time period.

    It is underneath the Tray/Chute for the Fixed Optical drive, and very close to the board edge near the Modular Bay's inner end.

    Greetings To All!!

    Hope the holiday treated you well as did I - I rested - whew!!! I have a Dell Inspiron 1520 of which I am trying to either get the part number or the exact location of the motherboard for the tmp 1.2 security chip. Researching to find it so that I can order a replacement has proven a bit difficult to say the least. Appreciate any leads or info on this one.

    Have a good day

    The EEProm chip is a 25 series. I only know of 2 varieties so far, a 25P80?? and a
    MX25L800??. These are not exact but close to the complete number. I do not know their location on the boards in question.
