    Gigabyte GA-6OXT :: caps question
    by Foetuss
    Good evening

    I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
    Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around [B]very [/B]low ESR caps?

    But I was also suprised about the bigger boys, which are 330µF [B]25V[/B].
    Could it be they used 25V caps because they were cheaper / available...

    [help]820-01700 "mistery problem"
    by phantomEVO
    Hi to all, i don't know the real history of this board.

    the technician who gave me this board says: "i don't know the history of this board, it not switch to 20v. i have changed ub300 and ub400, than i've discovered to have short on 5v andi i have changed u7650. still 5v not switching"

    MSI MS-16J9 - Not turning on, no shorts found
    by Alecs25
    Hello,
    i have this MSI which is not turning on, a bit of history:
    It was not used for months, the owner replaced the battery because it leaked, even before the replacement the laptop was not starting, just LED HDD blue blinking and so the charger led also blinking. This behavior is still present.

    The only thing i done was to reflash SPI, nothing else done. I've just checked for voltages around the board.

    19v seems present and so is 3VALW and 5VALW. I'm not that expert, there is the schematic with the power sequence, but i never understood how to do the checks,...

    MacBook Pro 14" M1 Pro Battery related question.
    by Stephen
    Board was just repaired, great thing for us since the DATA was recovered, however the battery was just replaced with a brand new OEM battery and holds the charge well, I plug it in and the charge icon comes on (lightning bolt) then it goes off and comes back again and repeats itself, The MagSafe 3 Amber light is turning off and on constantly, which is telling me something else is going on, before I pull this board out again I was wondering if anyone has come across this issue since its a little new to me on this model. Battery is holding the charge well at 52% but it won't charge further, I checked...

    Help me understand this linear supply circuit.
    by прямо
    Was looking for a simple CV CC linear supply to build and came across this one.

    [url]https://oshwlab.com/svalentin544/lab-power-supply-0-38v-0-5a[/url]

    I etched the provided board design and populated it.

    The output voltage adjustment works.
    ​​​​​​
    The output current adjustment however, doesn't behave like I expected it to be. If PR2 is going clockwise, the output voltage decrease. Adjusting R5 has no effect.

    I don't have a load connected to the output at all.

    ​​​Can someone explain how the current adjustment...

    Hello friends, I have a question. They brought me this video card, a DELL RTX 3080. They told me that it fell and the impact no longer produced video.
    When trying it, it's as if it wanted to give video but in the end nothing, I already checked voltages etc. everything is as it should, but without video
    I suppose it could be a bios problem but since sometimes they don't tell you everything, I've searched for the bios everywhere but without success
    I can't find a backup or something to try to reprogram bios and see if it's the fault, could you help me maybe someone has one that...
