Lightning Strike and electrical power surge

Click For Summary

Discussion Overview

The discussion revolves around the effects of a lightning strike on home electronics, specifically focusing on the damage caused to computers and networking equipment. Participants explore the mechanisms behind electrical surges and the differing impacts on wired and wireless connections.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant describes damage to a wired computer's modem and router, while a wireless computer suffered severe damage to its NIC card and speaker system, raising questions about the cause of the differing impacts.
  • Another participant inquires whether the wireless computer was plugged into a power source, suggesting that power connections may play a role in the damage.
  • It is noted that both computers were connected to surge protection power strips, which raises further questions about their effectiveness during the surge.
  • A participant mentions that despite consulting with electricians and academics, no definitive explanation for the surge has been found.
  • Another participant suggests that if the motherboards were undamaged, the issue may have originated from the internet cable carrying signals between the computers.

Areas of Agreement / Disagreement

Participants express uncertainty regarding the exact cause of the damage and whether the surge protection was adequate. Multiple competing views on the mechanisms of the surge and its effects remain unresolved.

Contextual Notes

Limitations include the lack of detailed information about the specific surge protection devices used and the exact nature of the lightning strike's impact on the home's electrical system.

Recently, lightning hit near my home (as best as I could tell, not my home directly) and caused considerable damage to my home computer. I have a wireless network with 2 desktops...one direct wired using ethernet cable and the other using a NIC card. When the lightning struck, my wired computer lost the modem, the router, and that was it! My wireless computer lost the NIC card (it was blasted into many pieces inside the tower) and my surround sound speaker system. Both CPUs seem fine...and really all other components in the house are fine. I'm thinking the CATV line got struck and surged into the modem and router. BUT WHY DID THE WIRELESS CONNECTED COMPUTER HAVE DAMAGE, ESPECIALLY THE NIC CARD BEING BLASTED APART? Just wondering what was going there? Any insight would be greatly appreciated!

The computer's internet connection was wireless, right? I mean, was it plugged into the power source in the wall?
 
Both computers (gateway and remote) were plugged into surge protection power strips.
 
Sorry for digging it up. I would also like to know the answer to this one.
 
After several conversations with numerous electricians and academic professionals, I've yet to ascertain a definitive answer as to the occurrence of the electrical surge!
 
Hi CM

You were using NIC to connect the two computers. If there was no damage to the motherboards, then that would mean that the problem happened with the internet cable carrying the signals.
