T430 doesn't turn on - Help with troubleshooting? (self.thinkpad)

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?

is it better than libreboot in some way?

@Jumuta Skulls just uses SeaBIOS as a payload, so it mush simpler.

However you can still try Libreboot, but you need to dump your firmware and extract binary files from it (like IME for example, and vgablob if you have Nvidia GPU)

@Evv1L @Jumuta Incorrect. Libreboot's build system automatically downloads update files from Lenovo, to extract things like Intel ME, which is then processed through me_cleaner.

Dumping your factory ROM is still recommended, but you don't need to extract anything from it to build a full Libreboot image.

On Libreboot release ROMs, files like Intel ME are missing but can be added using the same auto-download logic from the build system. See:

https://libreboot.org/docs/install/ivy_has_common.html

We provide SeaBIOS and GRUB.
