What's the chance of lightning damaging my PC?

What's the chance of lightning damaging my PC?

Practically non-existent unless it's frequently storming and your building sucks. Even then it's still not the most likely occurrence.

Hello everyone, today my friend told me that whenever it starts lightning I should unplug my PC and unplug all cables connected to it to protect it from being destroyed if lightning strikes our building, but what I want to know is what's the chance of that happening? and during lightning and raining I stay home to play games, so if I unplug my PC I won't be able to play games, Here's our location and how the cables go in our apartment...

So I live in the 12th floor which is the top apartment floor in our building, above it there's the final floor which is the inventory of the building... And the hotline cable stretches outside the building all the way to the nearest hotline box (the nearest hotline box is literally 7 meters apart from our building), The hotline cable is nearly 70 meters long, that hotline cable is connected to the router to provide the apartment with internet because internet in Egypt is connected to hotline, then there's the Ethernet cable that goes from the router to my PC, it's about 8 meters long, and now there's the Powerstrip  that I got my power supply cable and monitor cable and speakers cable connected to, that powerstrip is plugged to the wall, the wall plug is connected to home anti surge unit...

 

That's pretty much how it goes in our house for my PC, So what's the chance of lightning damaging my PC when it strikes our building? and is it worth it to unplug my PC while it's lightning?

Im pretty sure a building that high invests in lightning rods so i guess you are somewhat safe? Im not sure though since lightning is pretty rare in my place (the last lightning i heard was 4 months ago at the least.


Im with the mentaility of "IF IM NOT SURE IF ITS ENOUGH COOLING, GO OVERKILL"

A few years ago, I had a DSL internet connection and my PC was connected with ethernet.

One fine rainy day, lightning hit the telephone exchange (which is less than a kilometer from my home) and destroyed my modem and my ethernet port.

I consider myself very lucky that it didn't destroy the entire PC.

 

That being said, chances of it hitting your building and running down a power line is very rare.

I think it doesn't have any rods, also I sometimes go to my grandma's apartment, I spend a week with her, I of course take my PC with me there, her building is only 3 floors with a 4th floor as rooftop, But the wiring there is kinda similar to the one at my family's apartment, so my PC is less likely to be damaged there because there's less probability of lightning strike, right?

Since our building doesn't "suck" and it doesn't frequently storm here, guess I am safe then? thanks for the simple answer

It isn't much the building, but more if the lightning strikes powerlines or telecom equipment in the vicinity.

I do disconnect my PC and modem (and other expensive equipment) when there's a storm and I'm there.

And how do you play video games when that happens?

You should really be using a surge protector. They're cheap and will protect your PC from a vast majority of lightning effects. If you have storms in the area there will be power surges.

 

A direct lightning strike is very unlikely and unless the equipment is extremely vital, it's probably not worth unplugging. There is no way to fully protect from a direct lightning strike. If lightning strikes a building it can jump across rooms as it finds a pathway to the ground. Lightning rods and such help but they are not absolute. Additionally the massive electric field permeates everything and can induce voltages and current in otherwise isolated equipment. Simply unplugging things helps but won't fully protect it.

Not highly probable but definitely happens and definitely causes irreparable damage to appliances.

You only need one bolt to hit the power lines and cause a surge, even if that is a 1 in a 100 year experience for your area.


QuicK and DirtY. Read the CoC it's like a guide on how not to be moron.  Also I don't have an issue with the VS series.

Sometimes I miss contractions like n't on the end of words like wouldn't, couldn't and shouldn't.    Please don't be a dick,  make allowances when reading my posts.

It depends on your grid. In the city, you're probably alright. My grandparents have a cottage out in the country and we've blown out a lot of electronics due to power surges. Again, this is going to be highly dependant on your area as just being in a rural area is no guarantee of danger. My house was once struck by lightning and a bunch of our electronics fried, but none of the computers. As a result, I unplug all my expensive electronics at night, but I'm probably overly cautious.

While the chances of a direct hit on a house is pretty low, it still can happen. You are more likely to get a damaging surge from a hit on a power line. Although that's still fairly unlikely, again, it still can happen. It's up to you to decide how much risk you wish to take or avoid vs. the cost and/or hassle of adding extra protections.

 

I have a whole house surge protector on my home plus local surge protection for each appliance or appliance group. The computer gear get additional surge protection through a UPS.

Just invest in a good surge protectors if you're worried.

Like this one

Or this one
https://www.amazon.ca/dp/B017VXU6GG/

 

Or really, whichever other kind you can find that has a relatively high Joule protection rating. Which means, avoid cheap garbage from no name brands or the dollar store.

Also, if it can protect Coax and Phone jacks, that's an added bonus since it will protect your modems too.

I don't. Find something else to do.

Our house already got an anti-power surge unit...

Actually, that isn't completely true. A whole house surger arrestor will protect from most surges coming in on the power line but surges can be generated inside the house, usually from the start up and shutdown of large appliances. In addition to whole house house protection, more surge protection is needed at each device needing protection.
