    I have originally mistaken your computer as a laptop :eek:

    The paperclip method is not for Desktops, nor for that matter is the Mobile password thread ! (My mistake, umm very sorry for originally telling you to post there)
    This happened because of 2 reasons
    1. Your original posts (months ago) were about a laptop password removal
    2. Your wording made it difficult to understand, and your actions (posting on two threads 1 a reply and 1 your original thread) Made me think (!) that this was the standard Mobile password member, basically doing the standard stuff I see every 2 hrs or so

    But, due to my assumptions, you were placed in the wrong forum, and therefore not helped :eek:


    I wonder if it would be best for me to make up for my actions, and actually provide help for you. I think I'd better!


    The BIOS password may be cleared from a Dell Dimension by moving the password jumper on the motherboard.

    The location of the password jumper on a Dell Dimension motherboard can be found by reviewing the Dimension User Guides. See below for your Motherboard layout

    For most Dell Dimension desktops, the steps to reset a BIOS password and clear all CMOS settings are:
    • Locate the 3-pin CMOS password reset jumper on the system board.
    • Remove the jumper plug from pins 1 and 2.
    • Place the jumper plug on pins 2 and 3 and wait approximately 5 seconds.
    • Replace the jumper plug on pins 1 and 2.

    1 fan connector (FAN)
    2 processor connector (CPU)
    3 power connector (12VPOWER)
    4 memory module connectors (DIMM_1, DIMM_2)
    5 serial ATA drive connector (SATA0)
    6 front-panel connector (FNT_PANEL)
    7 power connector (POWER)
    8 CD/DVD drive connector (IDE)
    9 PCI Express x1 card connector
    10 PCI card connector (2)
    11 FlexBay USB connector
    12 piezo buzzer
    13 password jumper (PSWD)
    14 floppy drive connector (DSKT)
    15 battery socket (BATT)
    16 RTC reset jumper (RTCRST)

    Here is the jumper ==> [​IMG]
    Here is the position to place it in ==> [​IMG]
    ie Remove from existing jumpered Pins 1 & 2
    Then place the jumper on Pin 2 & 3

    This should work :)

    If it does not work, or if you need any more assistance, I will be only too willing to help. Maybe this may bring us up to neutral (No anger or happiness) I hope so
