View Full Version : Dead imac g5- rev b (ALS) 17in. - anyone else?

May 31, 2007, 03:33 PM
Over the past month or so my imac has been experiencing random shut downs. Started out with the fan turning on and getting very loud and then the computer would just shut down. I took some precautions and stopped using my computer if the ambient room temperature exceeded 78 degrees. I also opened up the back panel and cleaned out the dust. Unfortunately that did not solve the problem.

Now my computer will start up only some of the time and randomly quit sometimes it quits after a minute or two some times I can get as much as fifteen or twenty minutes of use from my computer. When I opened up the panel I did not observe leaking or bulging capacitors. I called apple support and was informed that the model preceding mine is covered and the 20 in. version of my model is covered, but my 17in model is not covered under either repair extension program: http://www.apple.com/support/exchange_repair/imac.html even though my computer seems to be exhibiting the classic systems of a power supply failure.

Has anyone else with this particular model of imac encountered these problems?

I have been a loyal apple user since the mid 90s and over all have been satisfied with apples products, but their reluctance to acknowledge and their leisurely response in addressing the imac g5 problems have forced me to reconsider.

I posted this exact same message on apple's discussion forums and it's been removed - twice! I wonder why?

bring it into an Apple Store. If it's the power supply, they'll probably do right by you.

Sniff the vent on the bottom... do you smell a slight burning smell?

I have a 17" ALS. It's been good so far.... How much dust was in yours when you opened it up? I've had intermittent crashes on it... I guess it's crashed a few more times than my iBook, although I do different things on it. It's also been through at least two or three power outages.

when you cleaned out the dust, did you get out all the dust in the crack just above the bottom of the case? use a vacuum for that.

I cleaned the dust out pretty thoroughly - there was quite a bit. I ended up opening up the case and running the imac in order to observe the led lights. The lights seemed to indicate that all was well, but the power supply got EXTREMELY hot after only about 5 minutes, so I think Im going to just replace the power supply myself and hope that was the only problem (no bulging or leaking capacitors at least). I know that some people have taken the imac (rev b 17) to an apple store and been successful in getting the power supply replaced under the extended warranty. But it looks easy enough to do and I dont feel like dealing with the hassle. Already got frustrated enough dealing with apple on the phone :(

Thanks for the replies!
