I went on holiday and left my Mac on. When I returned the on button was glimmering (as usual) but the Mac would not respond. I forced quit by pressing the startup button. After it turned off, it has not started up again. What I get is the following: After pressing the button, the button briefly turns yellow (< 1 sec), there is a crackle sound, and then it turns off. The monitor never turns on, although there is a brief static sound. I have a good electrical connection. I've tried the button tricks to no avail. I tried to slot load a CD, but it does not take (a lot of resistance and I don't want to force it). I had an external drive that is fine (Thank goodness for this file backup!).<br>

hello. have you tried to disconnect the powerchord off and wait a few hours? also when you open the RAM door at the bottom of your iMac yu can see a tiny button. press it with an pencil or smtg similar a few seconds (do not press it twice in thirty seconds) then start your iMac.
Please let us know if these solve your problem.
Hi Taner!
I disconnected the cord. Nothing. It took a while to find the button you described (gray button resting on a square 'nut'. I pressed it as you prescribed (with the power cord not connected or connected). Nothing. The other message posted that I might need to replace the battery. Thoughts?

Hi Raynan,
the internal battery has a life-span of appr. 5 years. If it is drained your computer won't start. As these batteries are readily available and quite cheap it is definitely worth a try to buy a new one.

Hi Duane,
thanks for your input. I only had this problem once. It was a Performer with a dead battery and it definitely wouldn't boot anymore (after displaying the usual symptoms - system clock resetting itself - of the battery dying). At least in that case there was nothing unpredictable about it: once it was truly drained -> no boot. IMHO however, in the case of the "dead" iMac it is worth to check as this is an easy and inexpensive possible fix.

Hi Petra and others!
Note that whenever I press the on button there is a flash of light in the button, a brief sound (not a boot), and then dead. The screen never comes on. If the battery were dead, wouldn't I get NOTHING at all?
Second, I just called an apple service guy and he indicated that this is usually a bad 'video board' (cost of $200! to replace). Does this make any sense?
Ray
well, it could be the logic board (200 $), the power supply (??? $ -but in that case I doubt that your Mac would show any signs of life at all)), or the backup battery (12 $ at Radio Shack). If it were my computer I would try a new battery before exploring any of the more expensive solutions, but it is your call.
Well, I changed the battery, pressed the gray button inside the RAM door, unplugged the unit. Nothing has worked. Any other ideas, other than a new video / power board ($200 cost)? Thanks.

Hi Ray,
that is just too bad. Sometimes you get lucky and it is just the battery:

I am sorry,
