Hi everybody. I have a laptop Acer Aspire E1-472 that I haven't used in the last 3 years becuase there is a password that lock the access to the BIOS, and I never remembered the password.
There are some online tools to get passwords from BIOS like https://bios-pw.org/ and https://www.biosbug.com/, but none of them works.
However, every 3 failed attempts to enter a password, the system generate a "hint" number, which it is (very probably) to generate a generic password in some manunfacturer's key generator, but, I will say, in the last 2 years, I have tried intensively to find information about it but I couln't find anything in the web.
So, knowing that there are password generators in the web, I think there is a way to hack the password from this specific BIOS (a relatively old BIOS, the laptop is from 2014). I know, the laptop is old, but I think I could turn it very usable upgrading some hardware and software, but without access to the BIOS configuration, I can't do all I want to do, and well, the fact of trying to bypass or "hack" the password from such system as a BIOS really drills my mind everytime I turn on the laptop.
Another info:
*I Have basic knowledge about programming and hardware
*Things like removing the CMOS Battery and the laptop Battery doesn't work
*Hacking has been always an interest for me but I have never dived into it
*I used the software CPU-Z to extract information from the BIOS, but I don't know what really is the information, I think it is the source code, but I am not sure
*Here are some of the codes generated by the system in the post
