    Capacitor Replacement?

    I purchased a motherboard off ebay recently that is missing a capacitor: (just to the left of the battery above the RAM slot)



    Does anyone know where I can get it repaired?
    Main - Intel Core i5 2300 @ 3.5GHz, 8GB DDR3 1333Mhz RAM, Asus P8P67 Pro, Coolermaster iGreen 600w, GTX 480, Antec One Case

    Re: Capacitor Replacement?

    Your best bet is asking mates who can solder - that's an easy job assuming you know the value of the cap (although you can probably guess it from the surrounding ones). Any on-line services are likely to be priced more than the board is worth.

    Re: Capacitor Replacement?

    Overall I agree with agent, just want to add that some times you can find local places that will do these fairly simple repairs reasonably cheap.

    Re: Capacitor Replacement?

    Buy a soldering half-decent iron (with temp control), solder, sucker & wick. Ideally also some isopropyl alchol, toothbrush and toothpics for cleaning up. You can then resolder anything you like. It's a useful thing to be able to do - I replace caps on a lot of things, i.e. I've so far got two free LCD monitors from work which had failed caps, I get cheap routers from car boots which often need caps replacing, my DSL router has been tarted up with nice caps...

    It's also nice to be able to do proper wire joins with heatshrink, or basic car electrical repairs.

    Does it work without the capacitor?

    Re: Capacitor Replacement?

    Learn to solder and replace it. Its amazingly useful skill, i had a Geforce 8400 GS pop a capacitor and i just replaced it and worked as good as new for another 4 or 5 months all for £3.

    worth noting though that my small 25w iron couldn't melt the solder and needed to borrow my dads ancient 50w(i think) one, must be they use solder on pc components with higher melting points than standard solder would be my guess.

    Re: Capacitor Replacement?

    It's due to the removal of lead from solder (ROHS)

    Re: Capacitor Replacement?

    Yes, that and the fact that it's already been flowed once means there's not much flux so it won't melt very easily.

    Re: Capacitor Replacement?

    wtf, hmm. are you sure it is a missing capacitor? what is the mobo model?
    you will need to know the uF value of the capacitor... They can be buy from maplin store in the uk.... or RS components, etc.

    Re: Capacitor Replacement?

    Yeah i got mine from RS components but if you can't find one that's the exact value of those similar looking ones around it always go for bigger values otherwise it'll just end up exploding or doing its job incorrectly.

    It's due to the removal of lead from solder (ROHS)
    Yes, that and the fact that it's already been flowed once means there's not much flux so it won't melt very easily.
    I don't know why that didn't occur to me, was never sure why, thanks
