T430 doesn't turn on - Help with troubleshooting? (sh.itjust.works)

I just bought a used "faulty" T430.

It doesn't turn on at all (no lights, no sounds, no fan spin) and when I tried to turn it on with only the critical components (motherboard, power adapter and speakers), I got the same result.

I've also examined the power area on the motherboard, and it seems like 20V is getting delivered to the motherboard just fine.

But I've looked at the motherboard thoroughly, and I couldn't find a single part of it that looked bad.

Is this definitely caused by the motherboard, or could it be an issue with another component like the CPU?

@Evv1L @Jumuta If you're using Libreboot an a T430 and you boot with SeaBIOS payload, you can still configure use of non-intel GPU if one is present, by modifying cmos.default in flash, using nvramtool with the -C option (Libreboot hardcodes the default so you need -C); and you can add the VGA ROM manually, conforming to name in CBFS: pcivvvv,dddd.rom, where v is vendor ID and d is device ID.

SeaBIOS would then automatically execute it, and if coreboot is configured in this way to use the dGPU.

Thanks so much for the info Leah! I'll definitely keep this in mind when I flash the firmware. If I can get my t430 to boot, I'll definitely try to install libreboot on it.
