    Caps and how to find one to replace

    Hello everyone I have a question. I have a laptop and his schematic. Can anyone tell me how to measure or any way to understand specific of caps so i can buy new one?

    Also in case how can I understand if some caps of some dead Mobo i have, are ok to be replaced in my new motherboard which im trying to fix?

    Thank you!

    Just from my experience... Only problem is ceramic capacitors going to short. Without boardview is hard to find out witch it is on schematics. But mostly these are 25 Volt capacitors on main power line +19V with high capacity and are the biggest ones.
    There are known issues with tantalum capacitors in MacBooks going bad without short, but this is rare.

      Yes without schematics im able to find what to buy.

      But lets say i have a couple of dead mobo, and i want to take some capacitators and put them on another mobo im fixing.

      Is it possible to recognize them without schematics?

        Also in my schematic i have different capacitators which i want to buy, but im not really sure what to buy.

        0.22U_0402_25V6K

        0.22U_0402_16V7K

        1U_0201_6.3V6M

        0.1U_0402_25V6

        I can read up to voltage rating, but what are those K and M at the end? Or regarding the last one, there is no letter.

        Can anyone explain me?
