    Hi everyone.

    First, let me preface by saying that I do not have much experience with diagnosing damages in motherboards other than visual inspection and checking simple short to ground faults.
    But I do learn quickly, and really want to learn how to properly diagnose motherboard faults. If someone could have the patience to go over this board with me, it would be greatly appreciated.

    A customer came into my shop with a A2179 MacBook with an 820-01958-A logic board. The reason for bringing the laptop in is that the laptop stopped turning on.

    ASUS X54H laptop thinks it's always charging even with charger unplugged
    by flat-earther
    The charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.

    Windows also shows ''Plugged in'' when charger is not connected.

    This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
    Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.
    If I let battery run out and say it has 3% Windows will...

    Sharp LC-40LE830E white blinking after wallplug is off
    by bajdik
    Hello, on Sharp LC-40LE830E is everything OK. Working great. If I put the 230 V off and on again, it just blinking white standby LED. I can power on only via VOL- and CH+ and POWER button on TV. After that, I can power off and power on again without problem (by buttons or remote control) until the 230 V is connected. If i put the plug off and on again, just white standby LED blinking. TV needs three button starting again.. On the first look, the backlight looks great, no darker or lighter spots. Any idea what is wrong?
