    Acer E1-571G Q5WVH LA-7912P Rev 1.0 Bypass Touchpad Requirement

    Hello, i have Q5WVH LA-7912P Rev 1.0 motherboard on my old PC. I accidently broke the touchpad things when replacing the back and up case. After doing that my motherboard going to blinking orange light on LED2. When I properly seat that touchpad thing, it occasionally boots. I think the problem is because of this. I don't have a soldering iron, so I can't solder it there. Since I'm going to use the computer as a server, I don't need a touchpad. I'm also leaving a photo for better understanding. I need to short-circuit it and make it work all the time. Which pins is for short-circuit? Thank you.

    Mb not giving display has nothing to do with touchad connector. So problem lies elsewhere.

      When I seat this touchpad connector correctly, the motherboard displays.

        Get someone local who performs cell phone repairs to flux and solder this part back onto the board. It is a quick 5-10 minute job. Suggest to use a point to point soldering and not hot air since the hot air tool will melt or at least warp this connector.

          'Coz of pressure while holding the connector or earthing influence.

          I repeat, touchpad has absolutely nothing to do with post process.

          Look carefully near the connector and you may get a clue.

            Why doesn't current just bypass faulty capacitors.
            by Spudgun
            Hello esteemed members. I appreciate that my question will strike some as being somewhat childishly simple, but it genuine perplexes me! I have repaired several laptops before by removing a faulty capacitor that was short-circuiting the motherboard, whereupon the laptop would then work. For me, it begs the question that, if the current can bypass where the capcitor was when it has been removed, why didn't it just bypass it when it was present and faulty,? I can't get my head round the premise that if the other side of the capacitor is connected to ground, then why doesn't the current simply bypass...

            Hi everyone hope all are well

            I need a little expert advice on a issue I have and seeing as this forum is full of clever people I thought ask here as you never know.
            I recently repaired a logic board 820-01700 which belongs to a 16" 2019 Macbook Pro, however I seem to be missing a component near the T2 Rom chip and is U4730.

            The schematics say this chip is (M34128-FCS6_P/T) and it also says there is a bypass for it wondered if anyone come across either the IC or the bypass method.
            I suppose it's worth noting googling the part package brings up various...
