    A2289 won't power on
    by sauce
    Hi,

    I bought a faulty A2289 for myself.

    The USB-C meter was stuck on 5V.

    After remove the board the U3100 was corroded and also around but quite light.

    So I clean the U3100 and see R2834 in bad condition and its value was not good.
    I replace it and not the USB-C meter shows 20V, the fan is spinning, CPU is hot but nothing else no picture.

    The USB-C meters shows a very low current with all connected. It starts at 20v few mA and then stays at 20v 100mA.

    How mush current the board is supposed to take without nothing...

    ASUS X512DA BIOS MOD
    by Oficinadopc
    I'm trying to enable this Asus X512DA. This model came without backlit and I ordered a keyboard with backlit. As I've been searching on the internet, It seems that the bios as to be modified at the offset DD to 7E. Since I don't have enough knowledge to the task, is there anyone who can make it for me? I attach the original bios file.

    Really appreciate the help...

    Reading and Programming ASUS iRog chips - EPF035 / EPF 036
    by artesano1969
    Well, I think this is the first time I'm sharing something here, I hope it will help anyone that, like me, is trying to repair one of those damm ASUS motherboards filled with iRog chips. I've written a manual following my experience and findings on fixing a dead ASUS Rampage IV Extreme (R4E).

    The ZIP file contains the guide and (almost) all the software I've used in the project. But I think it's worthy because it took me a lot of time to find out a cheap way to work with these chips from Explore with a bare CH341A programmer, and the original EP Console program is really hard to find....
