    hi guys,

    Please help me analysis, your advise/instructions will be very appreciated.
    basic information:

    -MacBook Pro 13(Mid, 2012) MD101ZP/A
    -i5 2.5G CPU/4GB Memory(2 x2G)/500GB HDD/Super Drive

    recently, my mbp always auto shut down, all happened in sleeping mode(i close the LCD cover let the system go to sleep). then the unit can not boot up.
    Below is the detail symptoms and my try efforts:
    1, SIL(sleep indicator light) no response while i press the little button on the left side.
    2, plug in A/C adapter, still can not boot, and the adapter charging indicator light no response(only very weak green/orange light blinking).
    3, sometimes, i dis-assembly the bottom case. then unplug the battery connector from the motherboard, a few seconds re-plug it to motherboard...the unit maybe turn on, sometime failed.
