    Physical symptoms of a system struck by lightning

    Yes. Jumper J9G1 positioned right subsequently to your two SATA connecters on the motherboard. Tribulations are I am having a hard time finding the wiring diagram or a pin-out on that jumper. I even checkered the motherboard manual, no go on that moreover and I locate that strange, for the reason that most motherboard books demonstrate a pin-out for the entire the ports on the motherboard, additional than not this manual.

    They demonstrate the whole thing for the power supply's connecters additional than failed to demonstrate a pin-out for the motherboard additional than it is jumper J9G1 and my Dell motherboard has a dissimilar type ribbon wire, which does not assist similar to I consideration it would. To be truthful by means of you, I imagine we might have to call this board a victum of lightening and start talking regarding replacement by means of an innovative one. I mean when you actually imagine regarding it, it was zapped to some degree, so it might have several components that are damaged not presently one.

    Diagnosis without hesitation - and particularly remotely - constantly means numbers. No numeral means subjective answers that are vague and not authoritative. Merely helpful respond - merely method to eliminate every suspect - is definitive answers. Those numbers back in post 9 were straightforwardly definitive. Subsequent to post 9, merely two suspects remained - power supply controller or its input (power switch). Even an additional input (the purple wire) was entirely exonerated by three digits - 5.14 volts. So 50 posts afterward and we are tranquil speculating on additional suspects.

    Set the meter to permanence mode or to 200 ohms resistance. Probes shorted simultaneously must be solitary digit ohms or less. Push a number of sewing needles into the connector so that meter probes be able to attach. When the switch is pressed, the closed switch measures solitary digit ohms (or meter's permanence function beeps). When switch is released, then meter demonstrate infinite ohms (or meter no longer beeps). At present the switch has been tested.

    If switch is superior, then the merely remaining suspect - motherboard - is inspected where illustrated previously. If nothing originate (ie no stray metal fragment), then motherboard be obliged to be replaced. It is the merely remaining suspect. Be able to be replaced by Dell or via Ebay. Meter says his symptoms are inconsistent by means of lightning surges for numerous reasons. His malfunction is typical of a manufacturing imperfection. To have encompassed damage, together an incoming and outgoing path must be from side to side that power supply controller. That surge path characteristically does not exist especially when additional parts are a superior path (and are additional typically damaged as a result).

    It rush forward rarely pass from side to side a power supply. A supply is necessary to be so robust. Additional than a power strip protector gives surges a path bypassing fortification in the supply. IOW power strip protector creates damage easier by diverting a stream onto a safety ground wire. At present that current has a straight path into the motherboard ground plane. Protector totally bypasses protection previously inside each supply.

    It creates no dissimilarity whether the appliance is on or off. Most of them have seen power strip protectors earth a surge into an complete network of powered off systems. From protector into motherboard. Out via NIC. From side to side network cable into additional systems The path traced by literally replacing cracked or exploded ICs. The entire systems made running by replacing merely the semiconductors in that path. The entire additional semiconductors were incoming to the surge. Additional than without an outgoing path, the entire those additional semiconductors suffered no damage.
