    Stupid mistake recapping - I need your help

    Hello all.
    I tried for first time to recap an old motherboard but i did a stupid mistake !
    The motherboard had 7 G-Luxon 6.3v - 1000uF capacitors. 4-5 of them was obviously bad.
    I decided to desolder them all first and then replace with TMZ of the same values.
    But by mistake i desoldered also an 6.3v - 470 uF capacitor (same diameter-color but
    a little shorter ) !!! At the end i had 8 capacitors removed !
    Now i don't know were the 470uF capacitor was.
    The motherboard is a DFI NB32-SC (socket 478).

    So, please, i need help from the experts.
    Any idea were the 470uF capacitor was (2-7 place in the picture) ?

    a 470uF 6.3v should have been tiny. Are you sure the 470uF wasn't a 16v? If it was indeed a 6.3v, up'ing the capacitance to 1000uF from 470uF really won't cause any ill affects. I did a quick search, and could not find any detailed/high-res pics of this board.

      Thank you for your answer !
      It is a 6.3v - 470uF and almost the same size with the 1000uF.

      It is strange that i can't find a single image of this motherboard !
      Search for NB32-SC or NB32 REV.B returns nothing.
      Only some pictures of a similar motherboard with different heatsink and 2 capacitors between AGP and PCI slot (mine has only 1 ).
      Must be a sample or something like that.

      Thanks again!

        Use the 1000's and move on.
        wont hurt anything

          Thank you.
          I used the 1000's. Tested and everything looks OK !

            In most cases you can go up to the next value ( electrolytics have such a broad tolerance that it may be the same value in any case) with no problems. There are only problems with using them for time delays, and in such a case you will have problems anyway from tolerances.

            Going to a higher voltage device the same so long as it physically fits in the same space.

              The higher capacity will stress on-boot the current on the voltage regulators.
              But for a motherboard which is designed to handle high loads I think that this detail is not that critical.

                Asus ROG Strix Scar G533qm with a G733qm Motherboard, can I modify the Bios to accept G533 Bios
                by glovecaps
                Hello,

                I have a Asus ROG Strix Scar 15 (G533QM) that had a dead motherboard (Graphics card dead) and after trying to fix the motherboard with no success, I bit the bullet on a sale for a new motherboard. I ordered a motherboard for the 15 inch model which is the one that I have, and when the motherboard arrived it wasn't for a little while that I saw it was from the 17 inch model.

                My question is, can I update the Bios on this G733 motherboard to a G533 Bios.

                The reason for wanting to do this is that the keyboard isn't working as it should, and I think this...

                Legion Y540 17irh motherboard issue ( need help to know how to diagnose my motherboard)
                by Docus
                Hi everyone ๐Ÿ˜€,

                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 โ‚ฌ150, 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.

                HP Envy 17-3290NR 3D Blank Screen - motherboard Louis V1.1 6050A2489901
                by Archimedes
                Subject is a blank screen issue in HP Envy 17-3290NR 3D version laptop with motherboard Louis V1.1 6050A2489901 MB-A02. Production year is 2012. This one is a 2nd hand motherboard which I could use it for few months only. Suddenly no output from the internal display and also no signal from HDMI port then Windows out of order after few boots.

                Caps lock working normally and no HP's caps-lock warning blinks. Making a hard reset and replacing the RAM sticks or using different slots didn't help.

                Fans are spinning. Blindly could install windows11 and got the device manager...

                ASUS P5GC-MX motherboard recap
                by momaka
                Hereโ€™s another motherboard that needed a full recap: an ASUS P5GC-MX.
                This one was gifted to me some years ago by user Pentium 4, along with a few other goodies. It actually came in working order with no bulging or leaking caps. However, I noted there were United Chemicon KZG caps everywhere on the motherboard. The CPU VRM output (CPU V_core) was the only exception: it had only 2x KZG. The rest was 6x UCC TMV 4V 680 uF capsโ€ฆ which arenโ€™t any good news either.

                So here is what the motherboard looked like with its original caps:

                After updating motherboard capacitors, what to do next (Asrock K7VT2, SOLTEK SL-75FRN2L)
                by dragon3x
                Hi, I have some 32 bits computer motherboards that need repair, as they fail to
                power on.

                Here are some examples :

                (N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
                switching supply area).
                (N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
                than 6.3 V.)

                1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
                I replaced capacitors with aluminum-polymer.
                3300 microF/6.3 V. x 4 replaced by 3300 microF/6.3 V. (KYOCERA...
