Hi., I am working on this motherboard MB:marshmallow mb 15257-2n 448.07N06 . 002N ... The required voltages (3.3v, 5V) are ok but the pressing the ON/OFF button does not turn on the laptop. I just noticed that someone messed up with the BIOS. Anyway I was able to read the BIOS, uploaded it. Kindly if some can re-build the BIN files, Model Hp ENVY x360 15-aq100nx , Serial # 8CG710266V, thanks in advance.

7.2.4. HP
Your BID is BID081AD ,that bios has been posted on the forum quite a few times before,you`ll find a virgin using the forum search, or use the guides to extract your own.
Learning some basic hex editing is essential these days if you want to learn bios repair.Your bios vendor is insyde.Almost every insyde bios has the serial number and all other DMI info in plain text that can easily be copied from the backup to the new virgin bios.
Searching for the serial number 8CG710266V i found the DMI at starting address 220000 .The full block (area) to copy is 220000 - 22103F .
