A couple of weeks ago at the end of June my iMac started having a few problems with heat. Temperatures on the power supply were getting at high at 80c, HDD was around 65c and above, GPU diode was around 72c. Having worked on computers before the temps worried me especially for the hard drive and GPU. Throughout all this time the ambient temperature was 29c-31c. While that is high, it's within operating temperatures published by Apple. The HDD was exceeding the max operating temps specified by Western Digital for the WDC5000AAJS drive. In addition to these high temperatures my display started to exhibit image persistence or screen burn as it was called in days gone by. It was mostly concentrated to the top left of the screen roughly where the PSU is. Images here: http://www.flickr.com/photos/paulbeattie/sets/72157620740779954/ . While the image persistence was most prevalent in the top left it was not confined to this area. Some may say this is due to leaving the same image displayed on screen for extended periods of time, to that effect I turned my iMac off for 16 hours. Upon boot the screen was perfect, temps were rising though. So I opened Safari and Mail, I positioned mail towards the top left of the screen and Safari towards the bottom right. Within an hour of turning on, and mail sitting without changing the image was persistent albeit not as deep as it would have been. My next step was to run the Apple Hardware Test found on Disk 1 of my OS X install disks. After running for a while it found the following error: 4MOT/2/40000004: HDD-1323. In the couple of hours AHT was running, even it had burnt into the screen. Armed with this information I called Apple, the first technician I got was extremely unhelpful and told me to go to my nearest Apple Store (200 miles away!!!) he also said the error code was a logic board error. He didn't even take my serial number to know what product it applied to!! So I called up again and spoke to a relatively helpful guy who arranged to get my iMac uplifted and brought to a Apple Authorised Service Provider, my AppleCare contract stated "UPLIFT" when purchasing via the Apple UK HED Agreement. I was told the service provider would call within the next 24-48 hours. The call from the service provider came after only 30 minutes which was very impressive. I was slightly confused when the service provider asked me what the problem was, the reason for asking was that Apple hadn't told them any information other than my iMac was a custom order and the AHT error code. For reference they didn't even put the custom order specs just it was a custom order!!! That was 2 weeks ago... Since then I have been told parts had been ordered, they hadn't. I've been told the repair was complete and the machine was shipping back to me, it wasn't. I've had failed call backs, been placed on hold when Apple didn't want to listen to me anymore. I was even told because I bought AppleCare I have no consumer rights!!! The lies and dishonesty with Apple and their service provider have been shocking. Now to today, I still have no iMac, it's my primary and only machine at the moment other than borrowing the occasional moment on another computer. Apple seem to have no clue what's going on just now, they don't really seem to care. I have been speaking to a service agent called Morgan based at Apple's EMEA HQ in Ireland. I could try and say she has been helpful, she hasn't. She really doesn't seem to care if my iMac is fixed or not, any information she has I seem to be telling her rather than her finding it out for herself. When I try to argue my corner after she has told me something, I get put on hold as she doesn't want to listen. After this experience I am sick fed up of Apple, the after sales service is shoddy, a downright disgrace. Before my iMac I had a £700 Dell, Dell managed to turn up on my doorstep the next day with parts to fix this problem. Apple on the other hand cant even seem to organise what they have. It's appalling. The icing on the cake is that Apple don't even seem bothered by the whole experience. I've been buying Apple products in various shapes and forms since 2003 and never really had to deal with "AppleCare", any dealings in the past had been good. I thought it's about time others know about the truly shocking service provided by Apple now. I'm really disappointed Apple of all companies treat their customers like this.
