password bios Lenovo G570

I put a supervisor password and a password of user for a G570, Lenovo laptop, running an INSYDEH20 BIOS. Later, I decided to exclude the passwords, so I went into the Setup, press F2 and I chose clear password (something like that). Now when I turn on my laptop, the message "Enter Current Password" appears. I put my old password... "invalid password", just press ENTER. "invalid password". I have not forgotten the password, I just wanted to remove the password and now I don't know what is happening. How should I do for that matter?

The problem has been resolved. I have been using the numeric keypad and when I put the password I used the figures in "regular keyboard. I didn't know it's the difference in the number 9, for example, by using the numeric keypad and the "regular" keyboard

    Hi NiTrO!

    There is no default password BIOS. It looks like you already tried erasing the power on password. Password BIOS appear not just came out of nowhere. Your choice is either get/remind the password, or replace the motherboard.

  • Password bios Lenovo B50

    Hi, I work in a school and one of our students has managed to put a bios password on one of our new laptops of Lenovo b50-80. Start the laptop, bios application "password disk HARD security." We're not sure how Flash the bios to reset it - how can we do this? We have tried to remove the CMOS battery and took the laptop apart to see if there are jumpers, but there isn't.

    Any help would be great. Thank you

    I was hoping you'd be able to boot into recovery mode using the "Novo" button located on the right side, near the USB port. With the help of this button to start the laptop should put you in recovery mode (recovery of key) that is integrated with most of the units.

    If this does not work, the only two choices are to recover the password set by the individual or have the computer repair at a local authorized store.

    Go further, setting a master password for the BIOS entry may be something that you should look at. I suggest to download the user guide / manual and reading on the password levels available service. -IMO contacting parents and informing them that they would be responsible for the costs repair / replace the notebook can also be something useful - your call.

    Good luck.

  • Password BIOS and G50 - 30

    I have owned my Lenovo Ideapad G50-30 for a few months now and I ran into a situation that I can't fix on my own. I set up a BIOS password in case it might get stolen on my University campus. But now, after a few system errors and General hiccups (for example cannot is reinstall Office due to a stupid mistake) so I decided to reformat Windows. But I can't do that, because the keyboard hangs during the installation phase, which might have something to do with the current BIOS usb support.

    The thing is, I can't get into BIOS because I don't remember the password. Is it possible to reset on my side?

    After tedious guess I finally understood the password. Needless to say that I write it down in the future. However, you are incorrect in assumming that passwords BIOS accept special characters, when it is not.

    However, I really appreciate your help and would like to ask you about the one key recovery? What is it and how does it work?

  • Bug in the BIOS in G570

    The Insyde H20 BIOS the G570 and other models, has a bug that prevents the hard disk is encrypted. As I understand it, there is an error in the code for ACPI. It is possible to work around this problem by using the hard disk via an IDE connection, but it is complex to implement.

    This error has been corrected in a recent BIOS upgrade? I have v.214 of the BIOS. The updates to the BIOS on the Lenovo Web site do not have a cumulative list of changes, so it is impossible for me to know if it's been fixed.

    If it is not fixed, Lenovo will fix this bug, which can easily transform laptops brick? What are the consequences for long-term use of the IDE?

    This blogpost describes the details of the error.

    This thread has discussed for more than a year.

    This thread on the forum of TrueCrypt described a complex solution.

    v2.09 (original version), I've encrypted any drive (C, D partition) without any problem.

  • Password BIOS in Portege R500

    Hello!
    I found my old laptop, but cannot start - forgotten BIOS password. Disconnect CMOS battery did not help.
    Local support asked me to service offline, but they want too much money to unlock - this laptop is now less expensive itself.
    Support of the USA asked me write here
    May be someone can help generate answers unlock code?
    Model is Portege R500 PPR50E-06W012RU

    Protection of the BIOS is a very important feature for protection, so it cannot be discussed in the public forum.
    If someone writes here how you can remove the password BIOS all stolen Portege R500 can be unlocked.

    I know that it costs a bit, but this should be done by the authorized service provider.

  • How to remove/reset password BIOS on my Satellite A350D?

    Hi all,

    Unfortunately (but "strangely" especially!) my Toshiba Satellite a350d - 20 k PSALME-01D00RIT does not not recognize the BIOS password. It's the same password never. I used it for 9 months each time in order to allow the start of the laptop.

    However, it is a couple of days since she decided that now that password is incorrect. After having tried and tried, I finally decided to put the HDD on another computer as external drive in order to continue with my work... but here it is the panic: none of the computers I've tried is actually able to read the data on the disk!

    After spending a certain time frozen in panic, I returned to myself and start to ask around to figure out the problem. Someone said that the wrong BIOS password has something to do with the fact that I can not read my disk outside this laptop: you know, it's a kind of average security.

    However, the only thing he cares about me is that at the same time, I can't use my laptop and I can't use my data outside of my laptop.

    So, my questions are:
    (1) this model of laptop has this kind of password BIOS-protection also affecting my drive?
    (2) the BIOS password reset will solve the problem?
    (3) how to reset the BIOS password anyway?
    (4) how to recover my data on this hard drive of reading?

    Waiting for any comment.
    Thank you very much!
    Kind regards.

    Hey guys

    BIOS password is very important security feature and we can not debate on this subject on a public forum, especially the Forum of Toshiba. Following your logic all stolen but with notebook BIOS password can be unlocked.

  • How can I change/remove password BIOS on Satellite A300?

    I have a satellite A300-1BZ running Windows vista Home premium. For some reason, there intermittentlystarted requesting a password of BIOS or boot when I turn on. I have never put this password myself and have no idea how or where to look to remove it.

    I can turn on if I remove the battery without asking for the password, but if I shut off and turn on again, then it asks again. Advice apprecieated.

    Thank you.
    Chris

    The history is somewhat strange. Cannot set password BIOS only.
    Is anyone else using your laptop?

    > I can light up if I remove the battery without asking for the password, but if I shut off and turn on again, then it asks again.
    To be honest I don t understand this. If you just understand that you can use your laptop and bypass the BIOS password if you turn the notebook on power only, right?
    But with the battery inside it start and ask BIOS password?
