    you probably should contact that guy

    failing that, if you're really careful, you might find a round silvery battery somewhere in your laptop's circuitry. take it out and wait a good length of time. put it back in and your problem is solved.

    Try to conntect the guy first.

    Failing that there might be a jumper that will allow you to remove the password. You just have to know witch one.

    Heh yeah, contact the guy first

    If it was a standard tower PC, I'd say go for it and just reset the battery/clear it with the jumper. But since it's a laptop there is just too much risk of messing things up.

    Did anyone mentioned contact the guy?

    But seriously, contact him. The password may also be on the manual somewhere where it discusses BIOS features or on the seller's booklet... or it can be your seller's firm name.

    Depending on what BIOS you have (and version), there are a few programs out there that can reset the BIOS. I had to do this with one of the computers I had and it worked just fine.

    I did some searching, CMOSpwd is the name of the program and is freely available for download from many sites like zdnet, etc.

    The following can be typed into the Console/DOS Debug program "Debug". Open a console window and Type "Debug" you'll be prompted with a '-'. Type the following:

    AWARD BIOS
    O 70 17
    O 71 17
    Q

    PHOENIX BIOS
    O 70 FF
    O 71 17
    Q

    GENERIC
    Invalidates CMOS RAM.
    O 70 2E
    O 71 FF
    Q
    Another method...

    A
    MOV AX,0
    MOV AX,CX
    OUT 70,AL
    MOV AX,0
    OUT 71,AL
    INC CX
    CMP CX,100
    JB 103
    INT 20
    <RETURN>
    G
    Q
    I've tested the above Award Bios trick, and it works... Others, you're on your own to try, I have no guarantee that these will a) Work b) Screw you up even more.

    A little late to the punch but I thought I would add few ords here. Some laptops, like IBM, Dell and a few other big name brands use multiple passwords. One for the system, one for the harddrive, one for the BIOS. The hard drive one is a particularly nasty one as removing the drive from the system and trying to access it is futile. Only recourse is to either pay a third party vendor to recover the passwordl, pay a third party vendor for a tool and do it yourself, or semd the drive in and get the password removed by the manufacturer....proof of purchase required in these cases.

    BIOS Password and Locked Hard Disk Recovery

    There is a tool out there that may be of assistance to you though and anyone else who is experiencing this issue. Not only for a lptop, but for a desktop system as well. Christophe Grenier has continued the development of CmosPwd which you can get here. It comes with the source code as well, so any interested parties can tweak the code to do whatever they want.

    I realize this is late and probably no good the person who started this topic, but I figured the information might be helpful to someone.
