    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....

    It runs, but after 10 -15 seconds stops working.
    Sometimes it shows error E1006.
    I can't find this error explication.

    Battery not charging in ASUS G532LWS Motherboard -> BQ24780S
    by cope
    Hi everyone,

    I have been working on a no power issue with my personal ASUS gaming laptop. It went dead a few months ago.

    Some history:

    Since then, I've found a blown mosfet on the GPU line which I replaced. It started up without a battery, then when I added the battery back it wouldn't start up again.

    As a result, there were some blown components around the BQ chip. (The BQ chip itself - BQ24780S, the low side battery mosfet (shorted), and a resistor -> all replaced)

    Now, with a new battery the system will start up and run off...

    How do I flash bios to an Alienware M16 R1 AMD edition?
    by Arc717
    I am trying to downgrade my bios on my Alienware so I can undervolt & overclock my CPU, and overclock my ram. I need to get to bios 1.2.2 for this. Dell doesn't allow downgrades, and their bios file is an exe compiled in c++, so I can't decompile it easily. I am wondering if I can flash the bios manually using a usb flasher. I would like to know if this is possible, and if so, where the bios chip would be. I know flashers are pretty cheap and the bios chip is 8-pin. There are two of these chips only when I open the back panel of the laptop. I'm not sure if there are any on the other side of...

    A1706 short PP3V3_S5
    by madjid911
    Hi friends,

    I have a macbook pro A1706 820-00923-A that won't start no signs of life, no liquid, checking the voltages I found PP3V3_S5 was shorted, I removed all the processor coils, but when I 'injects a voltage it is the processor which reacts, can you confirm to me that this is definitely coming from there please?

    I have 20V on the usb-c connector, and 13v stable on​ ppbus_g3h.
    I saw that a track had burned out on PPVIN_2V7NAND_LB after resistor R9350
    I injected voltage on L7660 pin 1 in short but only the processor reacts

    Thanks for your...
