    Macbook 13" 2010 .brd not matching schematic.pdf

    Hi,

    So I have a Macbook 13" (Motherboard 820-2879-B) that doesn't want to turn on. Theres the green light on magsafe but it doesn't want to charge the battery nor turn on the laptop (Even when the battery is removed).

    I'm trying to find the problem but it looks like the schematic doesn't match the board file (I've attached them. I got these files here on the forums).

    I'm trying to look for U7201 but I can't seem to find in the the .brd file. Do I have the wrong .brd file? IS it missing components?

    Thanks!

    Try these,

    also, did you test charger with multimeter and took logic board out and disconnect everything attached to it and try to boot from pads in the logic board first before further troubleshooting?

      Hi goodguy91, those files you gave me are the same ones that I uploaded (Except the document I upload doesn't have that water mark all over the pdf).

        You have the right file, but there is an error in the schematic.

        U7201 is a TPS51125. you can see it in schematic at page 3, and also in page 59, but as U7200.

        Try search U7200 in .brd and you have it.

          Thats odd. In U7201, VOUT1 is PP5V_S3_REG, which one is it in U7200? Pin 13?

          Thanks!

            You have =PP5V_S3_REG at pin 1 of L7260.

            If you want to know more about TPS51125, you can download its data-sheet.

            Regards.
