this one works well and easy trick for me on lenovo v15 ada if you experience black screen issue or facing obstacles loading defualt bios keys heres the only method that works perfectly on semibricked bios not yet tested on bricked bios .
1. download https://www.badcaps.net/filedata/fetch?id=3647825
2. extract file
3. name the extracted bin file E8Crisis.bin
4. drop the file named E8Crisis.bin on fat32 usb drive formatted mbr or gpt try both for most laptops start with mbr format then try gpt
5. turn off laptop
6. unplug charger
7. insert usb
8. press and hold Fn+R
9. plug charger while holding Fn+R a red light should start blinking on the left side of the laptop
10. while holding Fn+R press power button to turn on the laptop
11.if everything goes as instructed your screen will go back and a bios flashing process will show up on it
12. release Fn+R wait a few minutes for the process to end and pc will go back to normal
13. once done and booted to windows install the latest bios available on lenovo website
14 load default setting in bios

Hello,
I have a Lenovo Ideapad 3 14ADA05 with a unknown bios password that a want to remove

I pulled the bin file off the bios chip but I can't seem to find where the password is located to translate it from a hex editor.
Any help would be greatly appreciated. Thanks!

I have found Password string in binary file (offset 0x00310529) and set to 0x00 somme bytes inspired by another patch I found on the site but it didn't change anything. In the example I found there were two Passwords to patch, for me only once.

A picture is better then one thousand words.

A picture is better then one thousand words.

The rules override what you think is right. We can copy text easily, why should we who are giving help have to look at a picture and type it ourselves. Very often the pictures that are posted are too small, rotated 90 degress left or righ, upside down or blurry. In such cases rather than being worth a thousand words it doesn`t mean anything and wastes our time.

There`s a number of reasons why we ask for the serial number -

We can find the bios/update at the manufacturers support site.
We can check the laptop model type (lenovo) or configuration (Dell)
We can check if the posted serial number which is usually on the sticker matches with the serial number in the bios, or EC.
Asking for the serial number might put off some from posting at all if the machine is stolen.
We can check if the bios has already been posted by someone else, or by the same member using a different account asking for the same bios to try and get help quicker.
