I have an eMachine EL1352-01e which I brought from the states. When I first plugged it in here in Thailand there was a small pop, flash and smell of burning electrics in tha back right next to where the power plug attaches, and now there appears to be no power to it. However when I touched the metal frame, I got a small shock, which is odd because my house is grounded properly. At first I suspected I misread the power rating, but it says clearly on the side "Rating: 100-127/220-240CVac 6/3A, 60/50Hz" AFAIK that should be OK in Thailand. Am I wrong? The computer worked back in the states. If I am needing repair, any suggestions where I can do?

Some electrical devices mostly older ones have a switch to set the device for the correct input voltage. Is this possible on yours? And you did not see it? I think I've seen these on units that do not use the small power brick/transformer but the power cord fits directly in to the back of the device.

These are extremely low-cost PCs so I am almost certain the PSU is 120/60 only with maybe 350 W (a quick Google says as much). You might take it to a PC repair shop and have them try to replace the PSU; there's a good chance nothing else got fried. Or you can look for one and replace it yourself.

Moral to this story never bring any electrical item from the USA to Thailand 110 volts does not like 220 volts. As the above says take to a repair shop and maybe.....

I once saw a printer brought here from the US. It was certainly US (useless) after it had been plugged in. You have probably just blon the power supply. A new one may sort it.

From my experience the slash (/) usually means that you have to manually switch between the power ratings.

Auto selecting devices state 100-240V for example.

Replacing PSU is very simple and easy; you can do it or shop can do in about 10 minutes. PSUs are standard sized but will vary enormously in quality. Don't go just by the wattage rating, some awful trash available and in very common use here, ofthen with high (500+) W rating. The weight of the unit is a quick and (very) dirty quality check ... heavier is better. An acceptable PSU will cost at least 800 baht (labor extra), a proper quality unit will be 2000 baht+. The latter is really overkill for Emachine which is barely an entry-level grade of unit.

Yeap, you probably didn't change the line voltage setting for the power supply. Page 10 of the user's manual has the Caution notice and talks about setting the switch. Pretty standard for desktops. See attached. I like how they use the "should" word in the Caution notice that you "should" move the switch to the 230V setting when in a part of the world that uses 230V/50Hz. The "should" word is the wrong word to use; the word "must" is more appropriate as 120V only devices will almost always smoke themselves when plugged into 230V.

Changing out the power supply should be easy and cheap if it's a standard power supply. Cheers.

The most important to thing to look at when deciding on a PSU is the +12V rail. A higher amperage is preferable, and is always better. A 500W PSU may seem adequate, but if its +12V is too low, it may not be able to power a modern computer. PSU's with a high +12V rating also cost signifcantly more.

Switch on back around the plug to switch the voltage. Anyways hopefully you didnt zap any of the other components. First step just take out the power supply and find a new one. Easy to do and not that expensive to replace.

Thanks all. I see the switch now. How did I not know this. :( Feeling stupid. Guess that is why they say RTFM. I will replace the PSU and hopefully that will fix the problem.

I'm a little worried about the frame being electrified now when it is plugged in. Why would that be?

Hopefully the motherboard was not damaged, but it could have been. I say this because during the first few months of being in Thailand I smoked my Vonage VOIP box I brought from the States. The box uses an external power adapter/supply...puts out 12V if I remember right but operated off 120V only...and I knew this. I had a 220 to 120 voltage step down transformer to plug the power adapter into...and I actually had it hooked up like this...everything worked fine.

But one day, I was doing some rearranging of the different devices I had plugged into one power strip (i.e., VOIP box, DSL modem, wireless router, cordless phone, etc) and somehow got confused and plugged the Vonage power adapter straight into 220V and it smoked quickly. I got a new 12V power adapter that runs off 220V but the VOIP box didn't work. I took the cover off the VOIP box and could smell some components had also been burnt/smoked. I guess when the power adpater got smoked it allowed a surge of DC power to the VOIP box, probably a voltage much higher than 12V DC, and it smoked the box also.

So, hopefully your motherboard is still OK, but just realize there is a chance it may have been damaged also. Not only based on my one example above, but from my experience/knowledge gained from my earlier work years in repairing electronics for a living. When power supplies go bad they "sometimes" damage the boards/components they are supplying power to. But odds are in your favor the computer will work OK with a new power supply. Good luck.

This still happens sometimes even with a UPS and grounded plugs. :rolleyes: TIT

Connect an earth wire directly to one of the screws at the back of the tower.

Thanks all. I'll get the PSU replaced today and keep fingers crossed. I think I may have to take the whole unit down as the plug from the PSU to the motherboard is very inconveniently placed under the HDD. :annoyed:

I have had same experience with locally purchased products when changed condo.

It was because condo developer cut a few corners and most equipment was faulty ie the circuit breakers etc.

I lost TV, Laptop, and few other things. Naturally i expected him to pay and naturally he refused.

Ended up taking lawyer and independent Electric engineer, who basically confirmed that the breakers were not properly installed so a power surge can go through at any time which does blow your electric.

What he advised was to buy the power surge protector and connect electric devices only through that, because it regulates power supply.

This kind of dodgy work is very common according to him.

PS. I could be using wrong language here, not too savy on the subject but those power boxes cost from 2000-6000 baht and it basically regulates power supply-keeping stable

I took it to the shop down stairs Big C between Dtac and the travelators/escelator thingys. It took about 2 weeks to order the PSU, but they were able to get an identical one for 990 baht. Saved 500B by installing myself and it works like new. I nearly ordered it off Ebay as I was begining to doubt they would ever receive it. I am glad I didn't because that would have cost 3500baht.

Thanks again all.
