Walter: Have you tried replacing the battery on the logic board? It will surely give out after a few months if you unplug your iMac [or switch off the power strip] when the computer is not in use, or in a few years if you leave the computer plugged into a live socket. When the battery fails, all sorts of strange things can occur, some of them similar to what you reported, including the apparent "self-repair" after 20 minutes.
Before you give up on this iMac, buy yourself a 3.6-volt 1/2-AA size Lithium battery and use it to replace the one already on your main logic board. In your model of iMac, the battery is readily accessible by removing a small cover plate on the bottom of the computer, through the same port by which one can add additional RAM. (Instructions are given by Apple somewhere on their website if not in the instruction sheet that came with your computer.) This battery is available in the U.S. from any Radio Shack retail store as part no. 23-026 for about $12, so its cost just for a test is not prohibitive. These batteries are manufactured in Israel by Tadiran (type TL-5101) or France by SAFT (type LS 14250). I think Duracell in Germany also makes a similar battery. If Radio Shack has no stores in the U.K., there must be other electronics shops or computer stores (not to mention any Apple Computer centre) that stock such batteries. They can also be purchased from web sites that specialize in computer parts, especially those for Macs.

Four weeks after AppleCare expired, needless to say. Two weeks prior to my warranty running out, the computer wouldn't wake up from sleep. The power button light went green, the screen went grey, but the HD would not spin up. I did a forced restart, but the same thing happened at startup. Power light goes green, grey screen, but the HD would not spin up. I put the hardware test CD in, and the CD-Rom drive wouldn't even take it. So I switched it off and unplugged it for twenty minutes. I plugged it back in, and tried starting it up again. No problems at all. I was quite puzzled so I called up my local Apple centre describing the problem and explaining that given that my warranty had two weeks left, maybe it made sense to have it checked up. They said to monitor the problem in the remaining two weeks and that if it came up again I should take the computer in. If not, it was difficult for them to assess an intermittent problem of the kind described. Of course the iMac behaved impeccably for the following fortnight... . . . <snip> ...
