    Asus X99-S VRM Problem

    I have a X99-S that had a problem with the usb, but fixed itself somehow but now it wont start at all.
    The problem is as follows:
    The 24 pin is plugged in, the board works, turns on but stays at 00, when no cpu power.
    When cpu power is applied the board starts shows 00 then off again, with or without cpu. I get @1.5-1.7v at inductors as a blip then shuts down, as for resistance at the inductors i get 8-9ohms with cpu installed and OL without cpu.

      Check +1.05ME voltage, and probably replace the attached RT8065 if it is wrong. To test if failed RT8065, inject 1.05V at +1.05ME before replacing it.

          Asus Zephyrus M16 / GU603ZW problem
          by lazaro.089
          Full name/ Model: Asus Zephyrus M16 / GU603ZW-M16.I93070T
          CPU: Core i9-12900H
          Onboard 8GB DDR5 4xMT60B1G16HC-48B:A

          Problem: This laptop was brought to the shop with the board already meddled with. Last technician (maybe without the right tools) removed an electrolytic capacitor (PCE9203) sensing resistor (PRS9801) and probably flashed both BIOS (U2802) and VBIOS(U7802).
          The laptop's behavior is: When connected, it tries to power up. CPU powers on, and (allegedly) the power sequence finishes and goes to S0 (PLT_RST = 3.3V). It consumes 600mA, ramps up to 1.100 A and...

          ASUS X712JA problem
          by AtelierRepa
          Hello,

          I have a problem with the bios, let me explain.

          With BIOS 1, the pc takes +- 30 seconds to display the ASUS logo (black screen) and to boot.

          I did a clear ME, my black screen problem for 30 seconds at boot is solved, it gives me directly the display and boots quickly.

          My problem is that now, once the charger is plugged in and I put a slight load on the processor, it bogs down to 0.39GHz...
          The only solution is to unplug the charger to get the cpu back up to speed. But as soon as I plug in the charger, it goes straight back down....

          Asus dabkxmb18b0 rev.b bios problem
          by greg1985
          Hi. I bought a damaged Asus motherboard, model dabkxmb18b0 rev.b. The problem with the motherboard was a faulty processor.
          I replaced the processor, but it arrived without a BIOS chip. I found one post on the forum, but my problem is
          I don't know which chip to program, and I don't have a schematic. Does anyone know which BIOS chip models are compatible with this motherboard? If so, please let me know. Thanks.

          problem with asus tuf A17 FA707NUR
          by boticario
          Hello everyone,

          I’m trying to recover an ASUS TUF Gaming A17 FA707NUR (Ryzen + RTX 4050, 2023 model).
          The laptop powers on, fans spin, but the dGPU (NVIDIA) is not properly initialized — sometimes it shows up in Device Manager with Code 43, sometimes black screen.
          After several BIOS downgrades/upgrades (versions 300, 301, 303) and EC resets, it thinking looks like the EC firmware (IT5570VG-256) might have a persistent fault or flag stored in flash.

          I already extracted the BIOS .CAP files and DXE sections with UEFITool and IFRExtractor, but I couldn’t find...
