hi. not sure if it is static electricity, but sometimes my imac 27 if i pass both hands on side or top i feel A LOTTTT of static electricity. even putting my hand on a metal surface to make a s.elect. discharge won't stop it. should this be the cause of the flickering?

I haven't noticed such on mine, and you won't notice it if you follow these steps:

a. Don't wear synthetic garments (jackets, shirts, underwear, pants. socks, etc.) around the house.

b. Take your socks off a few minutes before you sit in front of the computer.

c. When you sit in front of the computer, keep your feet in contact with the floor (rug, tiles, etc.)

What you may be doing is charging your body with static electricity, and then discharging it to ground through your computer. Wearing shoes, socks, etc., keeps you isolated from the floor. Your computer is grounded through the power cord, and when you get your fingers near the screen, the static electricity takes its closest path to ground through the cord. Dry indoors air also contributes to building static electricity.

Have you ever discharged static electricity on the light switch in your home? The static electricity is being discharged out your fingers to the nearest grounded object. This is quite a shocking experience :) I have been asked by customers to check their light switches because every time they touch them they get shocked. The first thing I tell them is to walk barefooted for awhile before they touch the light switch, and then to call me if they get shocked. They don't call back, of course.
 
My late 06 MBP does the same thing when charging. And that's not always, it depends where i charge it. Never had issues because of that

It's basic year 7 science, wear socks rub ur foot on carpart for a while turn off thE lights put ur finger towards a metal door knob and u will see a electricity bolt and get a zap :)
 
There is no static electricity generated in the iMac. The case should be grounded via the power cord. If you feel anything tingly touching the case you need to check your electric outlet's ground.
 
Yes!!!!
I do feel static electricity as well. This not only happens in the iMacs, but also on the Macbook pros and also in another dell laptop that I have which has a metallic case.

This happens ONLY if the place where you are plugging it in does not have GROUND connection.
This is the case in about 50% of the plugs around europe to my experience.
In any case, you don't have to worry about it, but just keep in mind that it will go away as soon as you change to a grounded plug.
 
probably i'm getting a ups soon. also my imac needs to go back for screen flickering fix. i called them 2 days ago, they said they can't give me a new one because it passed the exchange period but they will fix this one... well, probably will still get a new one anyway, i don't really care as long as they repair this one=P
 
My finger gets shocked every morning I turn my i7 on lol, I always wonder if it will be big or small but I prepare myself for it. But my i7 has been flawless for 6 weeks now, I love it.

yes, yes, exactly!! for example at home depending the plug i use, it makes the static electricity if i change to somewhere else it does nothing, but it was really a thing that didn't really bother me at all lol

well that's a nice way to wake up :D you get a full charge to start the day eheh

i hope that after this, people won't start making thread's about the iMac's i5/i7 capability to make the "ultimate" static electricity to is users, and complaint that the aluminum used it's from a bad batch of a aluminum recycle center, or something, and want the aluminum replaced or want the old white plastic back (don't get me wrong. i love the white mac's, i wish i had one). :D

Just touch your dog first, but it will hate you for it :D:D Just kidding, but it's true that sometimes I pet my dog and by accident send a spark flying her way. She hates that, too, and I feel quite sorry when it happens. She is a sweetheart and forgives me every time.
 
are u serious or just joking? lolol

never did that kind of experiments :D

Lol I'm being serious, remember doing it that night after school 15 or so years ago, (ah so long ago) and turned off all the lights closed the door rub my feet with socks on the carpet for a good 5 minutes and u see it and get a hell of a zap
