Acer ANV15-51-54UL Bios location

[Andrew Tackett]

Long story short had linix installed on my laptop. Got locked out of the bios to try and reinstall windows and reset the CMOS but now its in a security boot fail and I'm trying to find the bios chip to backup and try to relfash but I have a mismatched size bin file. The chipset I found has a 1MB limit so I assume its not the correct chip. winbond 25q8dewing 2347 but it is the only one I can find. CH341A and AsProgrammer.

25q8dewing is not a complete part number but 1MB is too small to be the main bios chip.

Keep searching for other similar looking parts on the board. May be from Winbond or other flash memory manufacturers. Post pics of the part if in doubt. So far, unable to locate a schematic for this logic board.

gigadevice aj2346 258256ey is what I have found to be the bios. But I'm pretty sure I messed something up as now I cannot get it to boot or power on at all. No fan and black screen.
