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?

    As far as I know for this on Thinkpad, there’s a problem with your firmware and try to take a boot firmware from another laptop T430. Reflash it, and let’s see if it works. If it not works, then by all mean, there’s something wrong in the CPU. Try to change it, and if its not work again, change the motherboard.

      is there a way you know of flashing firmware without the laptop working? Do I need one of those bios programmer clip thingies?

          thanks, I’ll try getting a soic8 clip and flashing coreboot with a raspberry pi

              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.

                    @Evv1L @Jumuta Libreboot does not yet auto-download VGA ROMs for T430 though. It does for Dell Latitude E6400.

                    I have on todo to rewrite the handling of VGA ROMs, so that they can be added for non-Intel GPUs on all currently supported Libreboot hardware.

                    On T430, Libreboot currently configures coreboot to only use native graphics initialisation, for the Intel GPU. On T430 models with other GPU, the Intel GPU is still present and can be used in this way.

                    Also, Skulls is a really cool project.

                  I see, I thought there were pre built images for libreboot though?
