Important NOTE about passwords in bios bug!

Hey everybody,

IM the proud owner of the laptop Lenovo SL - 500 series. I never had any problems until today:

I decided to add a supervisor and Boot password in bios to better secure my files, I found a huge problem here and I found the solution that perhaps others would like to know too:

Example:

Ive like password "abc123 #1" in the bios, he asked me to confim this password and I did it. All is well until now.

I restart my laptop and he invites me to type my password to start:

Password: "abc123 #1.

Jim

Hey now, that's strange, the password that I just put refused. (Stress level was up to 90% instantly, cause as you may know Lenovo data security is so good that you would need a new motherboard if you can't get the password!)

I have tried tons of passwords but he refuses the password. Until I found the problem and the solution of a lot of luck!

the symbol # is NOT handled correctly in the bios. If you set the password, it allows. If you try to change it and retype the password it allows. But when you're out of the bios and the password prompt is displayed. It wil not understand the special symbol.

What causes your password not valid cause is not the 'same' password.

Solution:

I replaced the # with the TAB key on my keyboard

So instead of typing the # I knocked my TAB key once (Yes it magicly is considered as a symbol).

So that was my password 'abc123' TAB '1 '. Instantly my laptop boot and I was able to access the bios again and remove my password set using the TAB key instead of the special symbol # in my password.

So for future reference: do not set a special symbol like password in your bios. Even if she acts as if it was OK. It will be brick your laptop and it will cost you a new motherboard if you find out what the symbol is replaced by.

In my case No. == TAB, I don't know what it is for other special symbols and im going to try it!

I hope that people will appreciate this information and this will help other people who accidentally brick it portable by applying a special symbol in the password here!

Other users of Lenovo good luck!

Séverine,

Thanks to consolidate related topics. Based on these discussions, their solution was to omit the special character when access to the bios, but this current thread's advise to use a different key replaces a special character. However, it doesn't matter as the most important thing is to ban the use of special characters in the first place. Don't you think?

Technokiddy,

I reported this problem and advised him to consult the version 1.28--> update BIOS (Bootable CD) - ThinkPad SL300, SL400, SL400c, SL500, SL500c

Before you can update this new bios, make sure to disable the BIOS password avoid any unexpected errors.

Problem fixes:
-Improved password security.
-Fixed an issue where the LCD brightness setting could not wo

However, I do not know if the use of special characters are not allowed or not in an attempt to put in place a new password.

There are a few questions that I need to confirm double with you also.

  1. Could you tell me how you insert the special character ' # ' for supervisor password?  The English keyboard layout and Netherlands's character "#" is given by shift + 3
  2. Are you sure you selected character ' # '?
  3. Go to the windows Notepad and press the same button that you press is the BIOS password settings. What character do you see?

    Hi XB

    Please don't get me wrong, but as a computer technician, you should know how it works.
    BIOS technical removal cannot be discussed in public forum because they are authorized personal only.

    The BIOS is very important security feature and many laptop owners using such method to block machines and access to the important data.
    If someone here explains how BIOS password can be removed everyone can read and unlock some laptops stolen for example.

    What I can say is that there are several different techniques, how BIOS password can be removed and it is not the same on all models of laptops.
    What you need to do is to tell your customer or your friend that the BIOS password removal can be made by Toshiba service only so it should contact the nearest Toshiba service provider and ask for help.

    Hello

    What password do you mean exactly?
    BIOS or Windows user password?

    If you're talking about BIOS password then I have some bad news for you; You cannot reset a unknown BIOS password. Only a Toshiba ASP technician may remove unknown BIOS password.
    But if you talk to windows user password, then you could reset/clear the password by the new installation of the operating system for this you can use a HARD drive recovery option.

    PS: I found this article on resetting a password account user in Vista or Windows 7. I did not try it, but some people on the net reported that the account password could be changed successfully

  • How to remove the password of BIOS on Satellite Pro M10

    Hi guys,.

    I searched all over the web to find an answer, but has no success. So I really hope one of you can help out me.

    I have a very old Toshiba Satellite Pro M10 with 512 MB in it. The laptop is protected by a BIOS password that I know. However, the problem is that I want to remove the password of BIOS completely. I know this isn't a big deal, but I find it annoying to type the BIOS password over and over again. Mostly because I am preparing this old lady for my oldest daughter. Furthermore, I just installed Windows 7 and it works well, but I have all the original software Toshiba, for example the HW configuration utility. I expect the download somewhere on the net, but unfortunately this is not as simple as that.

    Any help is appreciated!

    Thank you

    Jeroen

    Hey Buddy,

    It is easy to remove the BIOS password. Follow the instructions posted by Al - eX.
    As new password just enter anything and then the password is removed.

    I m wondering that you have installed Windows 7 on Satellite Pro M10. It is a very old book, and in my opinion Windows XP would be the best choice.
    In addition there are no downloads available for this model and Windows 7 on Toshiba page

  • How to remove the password of BIOS on Satellite 2450-101?

    I have a Satellite 2450-101 and it seems that my HARD drive is already damaged. I would like to boot from the CD/DVD drive, but it won't start? It has a power on password too and I want to remove it but I can not enter or it does not penetrate into the BIOS settings?

    What can I do? Any suggestions?

    Am I entitled? You want to remove the BIOS password?
    Unfortunately, something like this is not possible! If you n t the BIOS password you can not delete it! Only the ASP in your country could do this!

    So if you want to remove it, contact the authorized service provider!

    But you want to boot from the CD! Am I wrong? Why you t n try to use the F12 key to get the start menu?
    After mobile power press F12 and you should be able to choose the STRANGE as a source of start-up! But the CD/DVD must be inserted before using this option.

    Try this!

  • Bad password the BIOS at startup Satellite A series

    After the children have used the laptop by connecting to BIOS password I get "invalid password" I don't think that they have been in the BIOS and changed it, so the only thing I can think is the language has been changed.

    I had this before but have always managed to open a session.
    Is it possible to XP to change the keyboard layout?

    If Yes to what?

    Is there a round work, or is it repair £150.

    Thanks for watching.

    Hello

    Keyboard language can be changed in Windows XP.
    To do this, you must go to
    Control Panel-> regional languages and Options-> languages-> details tab
    Here, you can define an additional or new keyboard language.
    You can also use a short SHIFT + ALT key to switch between languages.

    But the main point is that this work of parameters only when operating system running Windows XP.
    In the BIOS, the provision could t be changed...
    So it is hard to believe that the children changed the layout of the keyboard.

    For me it s not explained why the BIOS password has been changed or why fake BIOS message

    However, if you are unable to boot up the laptop because of the BIOS password then you will need to contact the ASP in your country to remove BIOS
    You will have to pay for this service but I put t believe that it s expensive
