    hi, a few weeks back my macbook pro 15" i5 bought in usa in 2011 started to act funny and freezing after a couple of minutes of being on. i open it up and found 2 resistor almost loose, i try to clean the small are and lost 2 smd components marked as number 1 and 2 in the picture. it looked like a single drop of liquid in the back of the logic board. so after i lost the components i removed another 2 from a faulty ati hd pcix graphics card and solder them back to my logic board but with no luck...

    so im looking four a good sould with similar laptop to test the components and help me identify the missing smd's. im still not sure if its a resistor or capacitor...or any other.

    many thanks in advance, hope somebody can help me.

    i manage to get the schematic draw for this logic board, but i need help to decode it :)

    Hi, where i find the circuit schematic..or component map?
    like this [​IMG]
    I have only electrical schema for my macbook pro 13.3". i have a usb problem.
    I think to replace RCLAMP0502N smd component.
