Looks like another tech flashed a BIOS for FX707ZU4, missing S/N, laptop didn't boot as ME region is still in File System State : "Configured" according to MEAnalyzer
S/N on ASUS website says FX507ZI4
Try some of the BIOS from here: https://www.badcaps.net/forum/troubl...48#post3729548
If it works the S/N can be edited with hex editor, replace all instances...

Just rename the link, sometimes that works until Lenovo decides to delete it from their servers
Latest is JKCN52WW https://download.lenovo.com/consumer...s/jkcn52ww.exe

It's ready to flash, unless you mean the file in post 29 doesn't work
If that doesn't work try post 31 from https://www.badcaps.net/forum/troubl...80#post3702480Leave a comment:

Try, replaced the ME region on "orig+$0AN2300+outimage.BIN" from post 4, hopefully that fixes the NVME SSD
You extract it with WinRAR......Leave a comment:

That's the BIOS file you linked in post 22 (rename from .rar to .bin) with a clean ME region, unless you mean a different file that worked for you (minus the NVME), please attach it hereLeave a comment:

Looks like besides what SMDFlea commented about the misaligned resistor, there's also 2 missing resistors near it
Check this picture, it shows 3 resistors there https://www.badcaps.net/filedata/fetch?id=2096307
RC349, RC350, RC351, all 3 resistors are 33 ohms 0201 according to LA-K051P schematics/boardview https://www.badcaps.net/forum/troubl...view-schematic
(boardview is mirrored)

You'll need an IC that has a reference voltage of 0.6V and at least 2A output, haven't seen any small DC-DC modules on Ali that fit that spec
What about getting a donor laptop board and cutting that section? Anything with Ryzen 4000/5000 series CPU should do, cut the board to get the 0.75v regulator section and graft it somewhere
Best if you can get schematics/boardview for the donor
Some laptops use RT8068AZQW for that section, might be a starting point, or maybe that IC is also used for 1.8V, then you have to modify the feedback resistors to get 0.75V...Leave a comment:
