• Now, We could understand why this problem occurs.

    This is the exact reason;
    This problem occurs If PIC is located less than 30 CM to a charging notebook. If notebook is not charging this problem doesn't occurs. If pic located more than 30CM this problem doesn't occur.

    In my last post, I have told that this problem doesn't occurs on my friends notebook; Yes it didn't occur because we carried the curcuit near to his notebook and his notebook was working on battery.

    We have placed 1,2,3,4 and more decoupler on circuit. But it doesn't effect on this problem.
