Do you have a dump from the second SPI that's near the Thunderbolt controller?

No change, with or without battery. CPU gets warm.

It's a Lenovo IdeaPad 720S-13IKB i5-8250U version. ES322 ES323 NM-B491 rev 1.0

Was the same when I got it, interesting to note is that the laptop does not power on from the marked Type-C charging port. ONLY Thunderbolt 3 port works and does charge the battery. There's also no backlight on LCD or beeps from speakers. I'll attach the original dumped BIOS

I've tried the same image with no luck, both from here and linked thread. The machine itself powers on via TB3 port only with fan spin and keyboard backlight, 2 second later only power button LED stays on and then it power cycles. Could it be a deeper problem with the logic board?
