Thinkpads Forum

I have a Thinkpad 600X and I have set a Supervisor Password yesterday when I was tesing the functionality of the password settings.

I understand that we are not allowed to talk about how to disable or unlock a password that we don't know, but my question is, I have the password, just that I can't put a "BLANK" to clear it.

Is there a way of clearing the password by putting a "BLANK"? I tried to leave it to nothing and just click "OK" but it doesn't allow me to do so move on.

Appreciate any advice. Thanks!

I forget exactly (someone else will remember), but I think you use the dialogue to change the password and for the new password, press enter (not blank and enter). I have never used a Supervisor password, but I have cleared BIOS and Hard Drive passwords this way. You do need to know the original password to do this, and you say you do. Good luck, ... JDH

Go to the password section of the BIOS, type in the old password and then hit enter twice for the blank password. Save your changes.

Thanks guys. I've tried both but unsuccessful. Maybe it works on newer machines, but not the 600X?

I have to key in the Supervisor Password to enter BIOS. I'm ok and entered the BIOS screen.

(I tried, if I don't have a valid SVP, I can't even change the date and time!)

Now I can change everything else, except that I follow both your advice but when I click on "OK" in the Supervisor Password dialog, it doesn't do anything, just beep every time I press Enter. Neither can I click "OK" nor keep pressing Enter. The only thing that would respond is "Cancel". (on 600X it's a GUI instead of the ASCII type of dialogs like newer machines and desktops)

This is also the first time I set any Password (Supervisor or Power-On) on my notebook computers. I think I'll never set any passwords again. It is relatively easier to clear the CMOS password on desktops (not using any short-circuit / battery drain methods, but pure legitimate login and change the passwords).

Anyway, if I get to know how to do it successfully, I will post my result here.

Thanks guys!

I'll have to go fire up my 600 and check the BIOS.

As you enter the password to get into EZBios, add a space to the end of that password.

Thank you, thank you! It worked by adding a space after the password!

I never thought of adding a space would do the trick, as normally entering as a password and adding a space means a wrong password being entered!

Gosh, thanks! The Supervisor Password is now cleared for good, in case I ever forget it later on. Thank you!
