HP Envy x360 13-bf0013dx ipa32 la-m024p rev 1b two BIOS chip?

[u666sa]

Why does this board has two BIOS chips? UC3 and UT3? Which one is actual BIOS and what is the other one?

Main BIOS should be UC3, 16MB (128)
UT3 is Thunderbolt firmware, 1MB (W25Q80 or equivalent) there's a dump here (mistakenly called "ec")

Thank you! Is there a schematics for my board? Because I found a short, coil getting hot. The other side of coil is to ground. I need to know where this one trace is going. Can't seem to find schematics for this board.

Couldn't find schematics either, for newer HP laptops they aren't available as far as I know
Post close up pictures of the area, also the markings of the ICs near the coil, maybe there's schematics from another board with the same IC you can use for reference

Nah. I'll rewrite the threat and post a new one with images etc. Moving my original threat back and force makes it confusing. It is confusing for me, locating it. It will be confusing for a next guy that will come here. Please move it back into offtop. The other chip is BIOS for type-c, topic closed.
