Why should you protect your computer?

Why should you protect your computer?

Well, if you don't, something like this could happen ...

Nice isn't it? One of the best I've seen so far ...

Both the modem and the motherboard got totally fried ...

It's a customers computer, it happened during the last storm we had.

Now ... if he'd have had a UPS protecting both the power and the phone line ...

Ouch, that's a shame for the customer. I always unplug my router from the DSL line when it's storming out. I've never lost a computer to lightning but I did have a VCR get hit once. It came in through the cable I guess, several chips and capacitors inside had exploded. Looked very much like that.

I've got surge protectors, they should do the trick. Never had any problems due to lightning.

Don't the fuses blow? Like the motherboard and power sources fuse?
odd... never even seen that?

The shock came from the telephone line ...

Telephone line --> Modem --> Montherboard

... so there are no fuses to blow! The same can happen through the network ...

Telephone line --> Modem/Router --> LAN cable --> Motherboard / LAN card

Normally only the LAN port gets fried that way though, because the modem/router blows up before it can do any more damage.
So just using a surge protector on your power isn't enough, you should protect your phone line / DSL / LAN too!

oh dear, lol, the weather here last week... blew up my granny's Sky box. The last time it was very stormy, 2 years ago, it blew up her cordless BT phone.

I havnt had this problem, never, with anything.

(except for the time I put a 12v adaptor into my 3.2v router. oops.)

/me is even more glad about my UPS, even if the battery doesn't kick in as well as it should.

Too bad for the customer. As always, the (US)$8.10 to $100 extra you spend could protect your $300-700+ computer. Last time that happened to an unprotected pc of mine, one of the hard drives blew in my old domain controller.

Recently, I lost several computers, and my dad lost his Big screen tv and dishwasher from... it was sort of the opposite. I have no idea what went on that day, but we got home to see the tail end of it. By that time it was too late... the power was flicking off and on at about 30x a second. For hours. Oh yeah. None of the lightbulbs that were on were any good anymore either. No surge protector will save you from that.

A UPS would until its battery ran out. If the voltage isn't constant it won't switch to mains power.

My laptop computer get fired last week. This was a IBM T42p and this wasn't the first time.

The computer is half burnt from the first motherboard blow up. This is the 4th ac adapter, 2 batteries, 2screen, 2keyboard, 2hard drive, 3rd motherboard...
A friend give me this computer because he was so bored. This is a 3 years warranty ... fortunaly !

But this computer fired when I was delivering a meeting for the end of the 2nd grade of my school. I needed to disassemble the computer in front of the jury to pllug my hard drive into my teacher's laptop to get my PPS and Application work. ..

So so bad. On the evening, when I called the IBM hotline, my GSM (cell phone) blow up (Sony Ericsson k550im). The batteries fired my sim card The next day, my old camera have also fired ...

Snif...

The most impressive fired's I've seen was my old GSM, a Sagem MYX6². The phone litteraly blow up in my pocket. The batteries was open and a strange liquid (like hot milk) was all around the screen. berk !

I'm a little weary about certain surge protectors....the one I just got a year ago for Christmas blew (it protected all of the stuff that was connected), but when I opened it, the fuse was still intact...the solder is actually what blew, breaking the connection where the fuse should have instead. Maybe it was the brand I was using, (It was an RCA), I think I should switch to APC. If a fuse can take that much current and not blow, then it's no safer than having all my devices connected directly to the wall.

The fuse didn't blow because it won't have been a quick blow fuse, but the solder will have got very hot and melted.

this happened to a friend of mine, his telephone lines insulation was gone and he got about a 50 volt spike and just set the modem ablaze, sad thing was it was a 2 month old hp workstation used for video editing, the whole thing was dead, however homeowners insur. replaced it for him, he was lucky.
