    Unplug your computer, take the side of the case of and remove the battery for 3 seconds, replace and your BIOS is reset.
     
  3. yeh try what Unisol says but...........if its a old motherboard it might be soldered on there....but im sure the other way wil work. Also try these:
    bios
    dell
    dd1
    dd0
    new
    rset
    rsetpswd
    i dout these will work...do the cmos battery thing

    Something wrong with the reset coms jumper on the motherboard then lads ? You can normally find this near the battery of bios chip. It should be marked.

    In some cases with LapTops the BIOS password can be reset using a floppy disk with something on it, or it needs to be sent back to the manufacturer. Thats prob so you dont void any warranties by removing pieces of hardware.

    If you want to know how to take you Dell Inspiron apart then goto Dell.com Support enter your service tag, then click on FIX MY DELL, there should be a ...

    Screw it, I will post a link
    Inspiron 4000 right?

    TRY THIS FOR BIOS PASSWORD MATETY

    Toshiba notebook BIOS password backdoor
    This method works on all older models. Newer models

    This is what you need:

    1. Your notebook
    2. An empty formatted diskette (720 kb or 1,44 mb)
    3. A second computer (e.g. a DOS desktop PC)
    4. A hex-editor (e.g. Norton DiskEdit or HexWorks)

    This is what you have to do:

    1. Start the desktop PC and start the hex-editor
    2. Put the disk in drive A:
    3. Change the first five bytes of sector 2 (boot sector is sector 1) to: 4B 45 59 00 00
    4. Save it! Now you have a KEYDISK
    5. Remove the disk from drive A:
    6. Put the disk in the notebook drive
    7. Start the notebook in Boot Mode (push the reset button)
    8. Press Enter when asked for Password:
    9. You will be asked to Set Password again. Press Y and Enter.
    10. You now see the BIOS configuration where you can set a new password.

    And that's all!


    New models try: FOR DELL LAPTOPS AND COMPAQ
    Toshiba notebook BIOS password removal via Parallel Port

    If you make a simple device that you connect to your parallel port, a lot of Toshiba computers remove the password when you boot it up. The device, named "loopback" by some, could be made out of any parallel wire with 25pins connectors. You should connect these pins:

    1-5-10,
    2-11,
    3-17,
    4-12,
    6-16,
    7-13,
    8-14,
    9-15


    For those who care, what is connect to what

    1-5-10, 1=Strob, 5 =data bit 3, 10 = ack
    2-11, 2=data bit 0, 11=Busy
    3-17, 3=data bit 1, 17=SLCT IN
    4-12, 4=data bit 2, 12=Paper End
    6-16, 6=data bit 4, 16=reset
    7-13, 7=data bit 5, 13=SLCT (out)
    8-14, 8=data bit 6, 14=Auto feed
    9-15 9=data bit 7, n/c sometimes +5v

    Strob is an output, tell the printer when data is ready.
    Ack is an input tell computer when printer has read the port.

    All other pins can be program as input or outputs.
    Except 15.

    Printer Computer port
    1 Strobe
    2 Data bit 0
    3 Data bit 1
    4 Data bit 2
    5 Data bit 3
    6 Data bit 4
    7 Data bit 5
    8 Data bit 6
    9 Data bit 7
    10 ACK
    11 Busy
    12 Paper End
    13 SLCT (out)
    14 Auto feed
    15 n/c sometimes +5v
    16 Reset
    17 SLCT IN

    Rest 18-25 Gnd
