    • Hello cente_nkn, if by chance you didn't 'create a "Supervisor Password" to prevent anyone from changing the configurations in the BIOS / CMOS Setup? than we are 'OK!' Lets just say [No] for now.
    • Bootup / Start the computer, and follow these steps:
    • 1. When you hear the computer start-up, there will be a message that flashes very quickly at the bottom of the screen, it will read; Press F2 or F12 or on other "Computers, the 'Key Sequence may be [F11]..."
    • The area of your attention will be [F2] Key at the top of the keyboard. The F2 Key will open the CMOS / BIOS Setup. paul7of9_15.jpg
    • 2. Once this screen appear, you will see a 'Listing" of different set-ups. There will be instructions in the [right] Help ? area. You be using the "Arrow Keys" to (Select and Choose Items). In the first screen, there will be on the (right of the screen).
    • 3. Set Supervisor Password = This is the "Password Setting that will prevent anyone from getting into without authorization this area that you are in now, to "Change or Configure" CMOS or BIOS setting.

    When i turn on my emp thinkpad it's all black and on the top it says password but i dont know it.


    Per Lenovo Support (they purchased IBM thinkpad a couple years ago)
    ote: Do Not Forget Your Supervisor Password! If you forget your Supervisor password, there is no way to reset your password to enter the BIOS configuration. Setting a supervisor password automatically sets the hard drive password. If you do not remember your supervisor password you must have the system serviced to have the system board and hard drive replaced. Proof of purchase is required, and this repair is not covered under the warranty.

    How do i get the supervisor password?


    it all depends on if it's bios or OS if it's bios you can reset the bios by opening the desktop panel and clear the cmos chip by taking the pin out and restart the system for about 10 seconds then turn off system and put back pin and go into bios set to defaults and that should clear it.But if it's OS you would have to buy a program that reset OS passwords like (reset password).

The user must enter the Supervisor password in order to get access to the ThinkPad BIOS Setup Utility in order to change the system configuration. If the Supervisor password is forgotten there is no way to reset it to enter the BIOS configuration. Setting a Supervisor password automatically sets the master Hard drive password.

    Bios password reset


    from the Toshiba support site

    The BIOS and Supervisor passwords cannot be removed or changed unless you know the existing password(s). If you forget your BIOS or Supervisor password, you will have to have the password removed by a Toshiba Authorized Service Provider. Although the prompts for these two passwords have the same appearance, the passwords are set and removed differently. If both are set, the Supervisor password takes precedence.

    I assume that the notebook will have a BIOS battery similar to a standard PC. If you are happy to disassembe it you may be able to reset the BIOS by removing the battery and/or locating the bios reset jumper

    Another alternative is to If this doesn't work or you dont want to disassemble the PC, you can try to build the Toshiba Parallell loopback.

    A lot of Toshiba computers remove the password when you boot it up with the loopback connected

    It can be made out of a 25pin male connectors (db25). Connect these pins: 1-5-10, 2-11, 3-17, 4-12, 6-16, 7-13, 8-14, 9-15, 18-25
