That's what they said too. I was running SL (notice I got the iMac in may). I posted a couple threads here before but nobody paid attention. I had around 129 kernel panics at the end of all this. The store staff didn't even understand it what was happening.

My best guess would have been environment. Is it possible that you had the previous router plug in the same outlet as the unit and was it located near the system? Perhaps the Mac wasn't getting enough juice to keep everything powered. Perhaps the router was too close to the system causing issues, perhaps you had selected a channel on the router that had too much noise and the system was having a hard time keeping a connection. Either way, I doubt that the other Macs would not have worked with the router you had, it was probably nothing than a setting that you needed to tweak.

Yeah I tried everything, I said earlier that I had 3-4 iMacs. I set them up in a few places around the house to see if that might change anything - nope, all of them had the kernel panics. I changed all the settings on the router (and reset it), and they still happened. I would have bought another router if I knew it was the router causing the problems, but I didn't know. And I didn't want to spend £100+ on a router that I didn't need...
 
Although I am a huge Apple fan, that doesn't mean I blindly accept everything they put out. If a hard drive fails, that is a legitimate reason to ask for a repair. Does dust get under the screen? Even a bug or two? Yep, all reported before. Should you expect a cosmetically perfect device when you buy it? Sure. But to spend 100 hours on the phone and go for weeks and weeks without a computer because of it is down right insane. A "normal" person does not do such things. Especially when the dust problem could have easily been remedied at home. Sure Apple technically has an obligation to fix the dusty screen but I don't know why you would subject yourself to all that pain over such a minor and easy to fix issue? Scratch? Who the hell cares. It's a computer not a Van Gogh. You need to to get some priorities straight. Don't sweat the small stuff. Life is too short to waste that much time and effort on such meaningless stuff.
99.9% of the time when you have someone needing to exchange a computer 4 or 5 times, you are either dealing with someone being unreasonable to an extreme or user error (right Prekesh?).

Sorry to interrupt , but you and most others misunderstood the OP , its not dust beind the glass panel he is/was complaining about , which is indeed easy to fix (popp off the glaspanel and wipe off the dust )
but he complained about dust inside the actual display , and thats not as easy as you need to completly dismantle the iMac , and then dismantle the complete LCD panel too , sure thats easy done too if you got the guts to eventually risk voiding your warranty if you damage something in the attempt .
Its even a Fact that some Brandnew iMac come with dust inside the actual display out of the factory , cause by the dusty air in china ... sorry i always thought one would manufacture high tech computing equipment in a dust free environment and not in some shed on a farm

And i expect if i bring any product in for a service to receive it serviced and undamaged and a scratch no matter how big is not on the list of things i would expect and accept

Apple is asking serious money for its products , we talk about computers , iMac's that cost more then £1000 and some close to £2000 and for that price you could expect to receive it in NEW conditon and not a dusty condtition that make it look like it has been already a year in use
(ok in The US they are about 60% cheaper that might explain why the Americans have lower expectations )

excess dust means only one thing...

I've found that excess dust particles are actually tiny CIA nano-bots. The moment you claim a device made by a major corporation is defective, they will be on to you. Ergo, for each additional instance you claim 'defect/return/exchange product' the more nano-spies you accumulate in your home courtesy the CIA and their operatives at UPS who deliver more of them right to your door. You saw them yourself, right?
Call Apple, apologize profusely. Tell them you were 100% wrong and you would like the original computer with the defective hard drive back, you will fix it yourself in exchange for them authorizing the removal of the nano-dust-spy-bots. (what ever the fick they are called) Say it just like that to the Apple rep. They'll send a secondary priority dispatch in to authorize the removal of most of them. Their population in your home will be down to the point where you will be able to block the remaining dust-mite-spy-nano-bot's telepathy rays with the use of a piece of aluminum foil folded over three times then shaped on your head like a helmet. Individuals with prominent cranial ridges need only use two folds, so you are saved the trouble of counting to three.
Yes, an aluminum foil helmet. Trust the instincts of the crazies as if they were the modern day equivalent of the movie-depicted noble savage.
 
This is what I consider unacceptable. No way would I have wasted this much of my life on these issues. You have to send it back for the hard drive problem but the dust could have been fixed in 30 minutes if it was that big of a deal and a scratch isn't worth 100 hours of my time.

I would have just swapped the drive and gotten back to my life :/

A scratch in nothing worth to you,you just about accept everything if it comes from Apple , thats where the good customer rating comes from i suppose

Now to your 30 minutes , you must do that regular if you manage cleaning the dipslay from the inside in 30 minutes

if you forgot what the thread is all about DUST in the LCD panel itself ,here what he needs to do in 30 minutes and he probably even has never touched a iMac's internals before



1. Remove the glass, unscrew the 10 torx screws, disconnect the cables and put the panel on a clean flat surface facing up. Follow this guide http://www.ifixit.com/Teardown/iMac-...eardown/1236/1

2. Unscrew 8 screws holding the frame to the panel. Some of them are beneath the cushions. They are different sizes so keep track of that. This guy came to this part http://www.youtube.com/watch?v=BNWASktH7-Q. Watch the video!

Now the hard part!

3. Put it in vertical position sitting on the bottom cushions and facing away from you. Peal of the metal tape on the top. You will see the 3 places for "pry opening" the frame. There are two more that you don't see on the top side. They are beneath the frame on the sides. You have to remove the metal tape in the corners in order to see those places. Look closely from the side. They look like small dents in which you put a flat head screwdriver. Don't pry it yet.

4. Now, you have to put the display face down so you see the tape that connects the frame to the panel on the sides and the bottom corners. On the bottom there is a black tape which you have to remove and you will see a prying place. Beneath the cushions are two more of them. In the bottom corners also, but you want see them - same as on the top side.

5.You see that metal gluey tape on the sides? Ok. It kinda glues the frame to the panel so you cant open it yet. You have to gently cut it loose from the panel! Yes this is the "do you have-the-guts-to-do-it" part. Take a knife or a razor blade and cut it so you can see the black plastic from the panel and the metal from the frame. When you're done with that you will see some more prying places for releasing the frame. 5 on each side.

6. Keep the display in vertical position. Pry open the frame on all sides. You need to pry between the black plastic and the metal frame. Don't pry under plastic. Try to find the prying dents it will be easier to release the frame. Rotate it if you need. Gently and slowly. On the top side be very careful! There are connections from the display glass to the logic board which are not to be harmed. I didn't even touch them so I don't know how careful you actually need to be, but try not to brake them. You can open the tin plate over the logic board. There are 4 screws and it comes off easily, but you don't have to do that. You can just unscrew 2 top screws so this plate releases the frame.

7. Remove the frame and put the panel face up.

8. You can open it now from the bottom side. The top side is connected to the logic board. Be gentle. Don't remove it all the way. Just crack it open.

9. Remove the dust from inside with a soft cloth. I used apple's cloth. There will be dust on the backlight and on the display from the inside.

10. Close it and put the frame back. Don't worry, it snaps back easily just be careful with the top where the connections are.


11. Screw all the screws back and assemble your imac.

i dont think you can manage that in 30 minutes if you never done it before



Thank you OGGY for those good and easy to follow instructions

Instruction stuff

Would this void a warranty? i'm semi ok about ripping into things which are towards the end of their lifespan anyway, but I wold be extremely hesitant to do this in a brand new machine. I'm just waiting on my new mac mini to be delivered and still in the process of deciding on what monitor to go with and all this talk of dust and taking things apart is steering me towards dell

You should buy a Dell screen anyway for the matt optionality! And anyway, you buy the computer for the computer bits. A monitor is a monitor. Save some money for the new iPhone!
 
I just want to see a picture of what the OP is complaining about, I want him/her to post a pic so we can see just how bad the dust actually is.

I habitually pull the glass off of my 27 inch iMac I have at work while working with my fingernails. Nervous habit. If I had some dust in there, I would just clean it, seems easy enough to do.

dell is a good choice
another good one is Samsung

it would if you damage something , if not then you warranty stays in place like if you upgrade the HDD for a SSD
