    Turning on and testing the power card without the motherboard

    I want to turn on and test the power card without the motherboard.
    I have 17IPS62 and 172IPS72 power supplies. Are the joins correct in the images below?
    If it is wrong, how should it be?
    Thank you.

      Let me place a 10 kohm resistor between them. Has it happened now?

        Inability to view the Bios with dedicated/discrete graphics card, Lenovo v520 PC, IB250MH VER1.0 motherboard
        by pippostino
        Good evening everyone, I have recovered a Lenovo V520 desktop PC, on which I have mounted an NVDIA GF9500GT 512Mb graphics card (and it is not the only one I have tried) to replace the one originally mounted, namely NVIDIA GT730 (Lenovo code FRU01AJ853), I replaced it because it has 2 Display Port outputs that I cannot use, as I don't have such a monitor or DP/VGA converter. The problem: Windows I can see it, but the Lenovo logo or the BIOS/UEFI, not. So I can't enter the Bios. To view the Boot or the Bios, I have to remove the dedicated graphics card and connect to the integrated graphics (therefore...

        Legion Y540 17irh motherboard issue ( need help to know how to diagnose my motherboard)
        by Docus
        Hi everyone 😀,

        I'm here today to ask for help with repairing the motherboard of a Lenovo Legion Y540 17IRH.

        To give you some context, I'm passionate about computer repair so much so that I've invested in a lot of tools and started practicing on dead and old hardware. I've been learning how to solder and desolder components, mostly focusing on phone repairs.

        Recently, I bought a broken Lenovo Legion Y540 17IRH for just €150, and there are two main reasons why I made this purchase:
        1. I already own the exact same model, but its plastic chassis is badly damaged.

        Please Help. Hp 8460P Motherboard not turning on.
        by wrongpolarity
        Hi All,
        I have been struggling to repair a HP 8460P laptop. Motherboard does not turn on. I have traced the problem to what seems to be a missing signal KBC_PWR_ON causing Trip2 on IC 5006 (TPS51123) to be activated.

        The following components have been replaced but the problem remains.
        C5191
        C5192
        U50006

        Listed below are voltages appearing on U5006 when the Motherboard is supplied with power from a bench power supply for the first 15 seconds or so.

        Pin 1 (Trip1) = 0.65
        Pin 6 (Trip2) = 0.65
        Pin 8 (Vreg3) = 3.31
        Pin...

        Asrock a320m-hdv motherboard not turning on
        by netgearnetgear
        Good day members,
        I have a asrock a320m-hdv motherboard that does not turn on. This weird thing is that it turns ON when I heat the motherboard in the vicinity of the m2 slot with a blow dryer. The there is a capacitor and resistor in parallel that has a voltage of 1.79v and 819mV on either ends. When I heat the board and it turns ON, the voltage is 1.79v and 803 mV. It turns OFF and ON normally if I wait a few minutes. On the other hand if I wait for an hour or more it does not turn ON anymore. I have to heat that area again and then it works. I noticed slight heat for example from my...

        Marian Trace Alpha sound card repair help
        by Christos Tsiligiannis
        Hello to the forum.

        My name is Christos, I am new to the forum here and i am posting from Greece.

        So i have this old German sound card from Marian, called Trace Alpha. To be exact i have 2 of them and i use them professionally for my small FM radio station here. The first one works like a charm, but the second one does not work at all.

        To be more specific in the same exact pc with windows 7 (i even tried 32bit) the one works while the other doesn't.

        So i tried asking for a schematic from the company and they would not give me one. Instead they...
