Asus Vivobook X712J bios

[brock-s]

I am attempting to remove a power-on password on an Asus Vivobook X712J, sn MG7N0CV08765227C.

The motherboard is X512A R.20 (on the silkscreen), and 13NB0KS0AM0101, 13N1-78A0101 (on sticker).
The EEPROM chip is 25B127DSIG by GigaDevice.

Attached is the BIOS dump as received. I have tried the info posted at BIOS guides, methods, resources and tools but when XORing the key found with the decryption key (posted by SMDFlea here:
https://www.badcaps.net/forum/troubl...=2#post1544866 ), it gives an error indicating the result is non-printable ascii. (Attached is a screenshot of the key section found).

Not sure if I'm doing something wrong or if that key doesn't apply to this model. Can someone check if I'm doing something wrong, or if there's another approach that should be used.
(note: I have a second one of these laptops with the same problem)

THANK YOU! That worked, power-on password gone! As I mentioned in the first post, I have two of these laptops. The second is the same model, with the serial number: M7N0CV08765227C. I don't mind doing the work if you can give me some guidance on the process to use. If you'd rather do it and post back the bios that is fine as well. Attached is the BIOS dump from the 2nd laptop.

Thank you! That one also worked without any problems. I am sincerely grateful for your time and help!

(To anyone who happens upon this in the future, this is an example of the importance of donating to keep this site alive. This thread is an example of two laptops saved, and there have been many others where I simply found the info I needed without having to post. Without this site, many machines would not have been fixed or not have been fixed so easily.)
