I don't know if that is correct or not but it's what I do.

The telephone junction box is not far from my computer so I used the earthing rod on that.
This means the phone line, modem and PC are all on the same earth so they should have no PD between them.

Excellelent I can do the same. Cheers.

Static is not a problem in Thailand, especially not in the rainy season.

I'm sure you're right DD but there's no way I'm going to start trying to "fix" the Pc. I'd just end up with a table of bits. We're also a bit of a long way from any techies.
How does this sound;
Stick in a ground wire to earth it.
or
Wait till it blows up, then buy a new one.
or
Get wife to "dust" it every morning before I get on to it. If she's barefoot it should discharge any static or other chargey build up and make it safe?

DD is right you should have it fixed, but if you dont see that happening, then you should ground the outlet it is connected to and use a power cable with a three prong plug.

Exactly Elie. House not grouned correctly. Call an electrician because it could be extremely dangerous.

Yes. It's due to poor wiring in the house, not a poorly built computer.

**dirtydog** · 04-07-2008, 01:35 PM

I have no grounds in my house, I also don't get electric shocks from my computers, when I have done before I have fixed the problem rather than stick an earth in and ignoring the problem.

**Thetyim** · 04-07-2008, 01:43 PM

The more I think about it, the more I think DD is right.
No way can it be right to have a leak to the case.
Adding an earth is curing the symptom , not curing the problem

Agree. If a PC or a peripheral is giving someone a tingle it is likely caused by a problem in the device. Moisture is usually the culprit. When humidity is high as it is in the rainy season, small amounts of moisture will accumulate and low voltage can easily be transferred to the case. If your system is in an air conditioned room less likely there will be a problem. Still much better to have earth on the system to prevent equipment damage and eliminate the tingles.

In my experience the PC is often not the culprit. Usually a peripheral. Any leakage to the case of the peripheral will be transferred to the PC via the USB cable shield.

BTW: Not necessary to rewire the entire house. Very expensive! All that needs done is to have the earth available at the outlets your PC and periphs plug in. If the plugs are on an external wall, drive a grounding stake outside the wall and bring in the ground wire to the electrical outlet/s.

I had the same computer in 2 different places, first 1 no ground in house, got shocked, brought it to my new place all grounded and no shock. It's the house not being grounded.

Accepted, but it isn't curing the problem.
The earth wire is just sending the leakage to earth so that you don't get a tingle.
This is safer for you but has not solved the problem which is a leakage somewhere in your computer

**jandajoy** · 04-07-2008, 03:38 PM

Weird. I've done nothing, changes nothing and it's stopped giving us (wife) a shock.
Humidity, as suggested?

Yep. That's been my experience as well.

Did you happen to unplug a peripheral? Did you touch the case with bare feet? May be gone for now but count on the problem coming back. Get a ground on the PC!!!!

**Frankenstein** · 04-07-2008, 03:47 PM

DD and Thetyim are right lads. There won't be any leakage if the equipment is properly built, whether it is connected to an earthed outlet or not.

The earth fixes the problem of getting shocks, but it does not fix the problem that some part of the equipment is not built properly.

There are standards for building electrical equipment. Equipment that does not come with a three prong plug in developed countries will be built so as to make sure no external parts are electrified.

No disrespect but this made me/us smile. I don't know why, maybe cos the pc is on the desk and wifey thought you were suggesting wierd going ons, Bless her.

Seriously though, all suggestions gratefully received and we've got a recommended sparky coming from Chiang Khong tonight to check out the house. If that doesn't fix it Pc will go to Chiang Rai in the next couple of days.

Shame in a way I was beginning to enjoy those occassional tingles.

Hence my touch with your bare feet question.

**jandajoy** · 04-07-2008, 04:08 PM

Is it wrong of me to accept said tingles through the soles of her feet?
Is that perverse?

That says it all, pcs are not built to electrocute small animals that are trying to sneak inside, if you have shocks from your pc then there is something not set up right, yes an earth wire will fix it as the electric takes the shortest easiest route to earth, and that aint your hand or foot when you got nearly 2 meters of grounding rod in the dirt outside, but then you are paying for electric to go into the earth without fixing the problem, yes you should earth your pc, but first you should fix the problem.

**Eliminator** · 04-07-2008, 08:31 PM

DD, NOT true on what you're saying as if your house is not grounded PROPERLY, you can get the same shock from any number of appliances you have in your house. Are you running a water heater in your house WITHOUT a ground? If so, then you are begging to die if the unit gets wet. Your fuse panel cannot work WITHOUT a ground and if it works at all, then you will probably be dead before the fuse kicks off.

Just a couple of years ago a well known actor was killed in the shower for the simple reason that his house was NOT grounded. Know of this other guy that got killed watering his yard and the gate light was not grounded and a wire shorted, the fuse did NOT kick OFF. Up2U as they say, NOT in my house though.

**jandajoy** · 04-07-2008, 08:34 PM

Fuck, now I'm scared. The old tent sounds best and fuck this computer malarkey.

I disagree.

Yes.
The fault being in the appliance

**Eliminator** · 04-07-2008, 08:46 PM

The FAULT is not the appliance as most NEW ones don't have a 3 pronged plug, so you must have your HOUSE, not the appliance grounded. Had a guy from HomePro to install my new stove in my house and he wired it direct to the fuse panel. I then asked him where the ground wire was, he says "no need, this is Thailand". He didn't leave my house until he ran a ground wire to the fuse panel. I like to think the fuse panel is working but I want anything drawing that much current to be grounded.

Like I said, UP2U. No ground in his house is still my bet on his "tingles". Another thing, if he was really getting SHOCKED instead of the tingle, then I MIGHT think that he had a problem with his computer.

You are talking out of your arse

**Eliminator** · 04-07-2008, 09:02 PM

Let's see now, I just checked my fridge, my hot water pot, my microwave and even my fan,tvs and NONE of them have 3 prongs to the electrical outlet. ALL of my outlets have 3 prongs and ALL are grounded to the fuse panel, seems pretty logical to me that I won't get shocked unless I grab an open wire leading to the outlet. Even if I do get shocked, I think the fuse panel should kick off. Why do you think the Thais sell all the extra boxes to people to CUT OUT EARLY if there is a short. It's because all OLDER houses are NOT GROUNDED and you can DIE.

Tingles not shocks, definately tingles.
Hang on..... MMMMMM yes "tingles" excuse us............
