    macbook pro 13" 820-01987-a power button issue

    this laptop works fine except that once it is shutdown, it will not power back up unless the battery and charger have both been disconnected first. then it will automatically power up just like it should. basically the power button will wake it from a sleep but it will not power it up from a shutdown. all power sources have to be detached first in order for it to power up

    this appears to be a pmu (u7800) issue. does anyone know how to access it? apple decided to hide the chip away with a metal cover that's soldered to the board
