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>

    Hi raynan,

    First, try the steps outlined here:

    If these steps fail, you should replace the backup battery:

    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 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.

    That is not always true. This is one possible symptom of a dead battery. But a dead battery does not always prevent a Mac from booting.

    The corruption of the PRAM is unpredictable. Non-booting is only one possible symptom.

    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.

    It is true that in the Performa days, a dead battery would frequently cause boot problems. Not always but very often.

    Changing the PRAM battery in the iMac is certainly recommended and can't hurt. However the chances of it solving this problem are far from certain.

    Hi Raynan,

    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.

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

    Alas, in your case it seems to be a more severe hardware issue that can only be tackled by an Apple service provider at some cost. Maybe you should check ebay for a replacement iMac (you can buy them for as low 50 $).
    I am sorry,
