    Repairing a Dell H535T Motherboard

    I need to repair a dell motherboard, that has two caps bulging on top.

    The caps are near the first cpu/memory banks and the model is:
    SANYO 1500uf 6.3V - 105º S.E. 99 WF

    I'm not finding the same model, can you give some advise another cap to replace them?

    The S.E. 99 has any special meaning?

    In case I can't find a good replacement, can I change them for example for 2200uf 16V - 105º, or is a very bad idea?

    Thanks!

      I have the ones you need but I don't have the ones I need. I always try to put the same capacity ones but think theoretically you can put higher capacity at the input of the VRM. At the output not really sure. I know main parameter of a buck converter is the inductor (choke) for ripple current as in here http://www.daycounter.com/LabBook/Bu...quations.phtml now capacitors resist change in voltage. AFAIK if you put them higher resistance to voltage change should be higher. But then IDK if you are dealing with a buck converter. Likely but not sure.
