New iMac 27" i7 - no power (failure) after 2 wks

May be a power supply issue...hopefully.

Since it's being fixed under warranty, does it matter what the actual problem was/is? 🙂

Those new big quad-core iMacs chew a lot of power, so make sure you are plugging the power cord into a reliable power source. If there's a power strip, get a brand new one (or at least make sure it's not too old). If other devices like printers and external drives and power adapters are connected to the same power strip, get one just for the iMac (and maybe one or two low-power devices) and connect the other devices to another power strip.

Hi,

I have a 24" iMac bought in Sep. 2007, and I also heard a "pop" just this past Friday. And now nothing. No power, no lights, like it's dead.

Brought it to my local Apple store, and they are going to order a power supply and new power cord, and see if this is it.

No guarantees though.

I'll repost when they have issued the repair.

My i5 iMac died about 2 weeks after it was delivered, and I'm now in a 2-week delay awaiting a replacement. Just 'pop,' and it was dead. I assume a power supply, but with that short a life, I asked for a replacement. I posted a thread below about my experience with support.

Sorry guys I hate to burst your bubble but I don't think you're going to get it fixed.
Mine did the same. You turn it on, you use it, then later on it pops and its off. Dead as a door nob.

I've taken it to my Apple repair centre in town and they said it was the hard drive and the Power supply. So they replaced it. And then I reinstalled everything again off my Time Machine and had everything back to normal and guess what..............the problem is back!!!!

So I know for a fact that it is not a Hardware problem. ITS A SOFTWARE PROBLEM.

My gut feeling is this, I install patches on my iMac (because its a good idea you do so) and I think ever since that when I did that, that's where the problem started. And I don't know which patch it was.

So really the problem is really software based and its stuffing up the shutdown coding (i guess) and you just hope and pray that it stays on.

I'm going to reinstall the OS and applications (again 😟 ) and see if that makes a difference. And not install all the patches.
