    impossible, You need to check the backup file before the clear works well.

    Hi all,
    I just registered to the forum. I spent quite a long time searching the web and studying some documents trying to understand how to reset the BIOS password for a HP elitebook 820 G3 I bought second hand. I discovered only later that the BIOS was locked by a password and realized it is impossible to reset the bios password unless you call HP to get a unique smc.bin file or replace the BIOS chip. I am moving on this last solution and I ordered the BIOS chip that is a winbond 25Q128FV. Before doing that I am kindly asking you any advice about this procedure. The vendor told me the chip is loaded with latest firmware and nothing more than replace the chip is required. I want to be sure this is correct and I will note face any other problem. It appears to me that the chip could be missing the basic info about the laptop...am I correct. What should I do in this case?
    Is there any other software procedure?

    Hi thank you very much for your support. I just need to know if your solution is an hardware solution or a software solution. My situation is I have a laptop elitebook 820 G3 and I can NOT enter/change/update the BIOS as it is password looked. I am not sure if the laptop can boot from another device. Please let me know.
    Thank you

    Hi,
    I am sorry but I am not sure about your answer. I would appreciate a little bit more clear explanation so that I can understand if I am able or not to do the job.
    I can work with file editing but, AGAIN, I can not enter the bIOS because of the pw.
    Thanks for your understanding.. I need to be sure before proceedind.
