    Start a repair thread in the laptop forum. We may be able to diagnose without a schematic.

    Start with the power adapter -> 2 x dcin mosfets & charger IC details. Most of the time, the fault is in this region.

      Thank you mon2.
      I just found the problem by looking closely at the motherboard with a big magnifying glass.
      Some tracks of the SIO chip were oxidized and I was able to repair the connections.
      I'm happy, my PC will have a second life ;-)

          Hello.
          Finaly I need the schematic for this mainboard because the computer only starts if the charger is plugged in. However the battery is good, if I unplug the charger only one second after starting the PC works very well on the battery, it's really only the start on battery that is the problem.

            ASUS TUF X570-PLUS doesn't power on: no VRM_EN signal.
            by ShadowAi
            Hello, I have an issue with the motherboard. Specifically, it doesn't power on, more precisely, the POST initialization doesn't occur.

            Let me start from the beginning, the motherboard suddenly stopped working one day. There are no beep signals from the speaker, and the debug LEDs are not lighting up. After inspecting it under a microscope and using thermal imaging, I didn't find anything that could be damaged.

            After that, I began voltage measurements, in which I noticed the absence of VDDQ, VDDP, VTT, and VPP lines. Later, I checked if there is an EN state on these lines,...

            Boardview/schematic for an ASUS E3-PRO V5
            by whatamidoing
            Hello,
            i'm looking for a schematic/boardview for an ASUS E3-PRO V5 (NOT E3 PRO GAMING, has a different layout).
            I'm trying to find out where i can find SKTOCC# other than from the socket in order to ground it for a Coffee Lake mod. It must be somewhere near/around the SIO but I haven't found a datasheet for the NCT5539D this board has.

            I've also found the schematic for the similarly named E3 PRO GAMING V5 but it has a different SIO so it's not of much help. And I don't trust myself to hold still a multimeter probe on top of a LGA socket pin to find where it comes out the...

            I need schematic and diagram for Asus X556U Rev2.0 mb
            by Kirve
            "Hello friends. My Asus X556U laptop is not charging, not turning on, etc. I wanted to repair the motherboard, partly for learning purposes. One of the capacitors is giving a 24V output, and one of the MOSFET pins is also giving a 24V output, and honestly, this surprises me. I think I need to replace the capacitor, but I don’t know the capacitance value. I tried searching for a motherboard schematic but couldn’t find anything. Can you help me find the schematic or diagram?"
