Power On Issues (delays) After Power Failure
Over the years, my iMac has been taking longer and longer to power up after a complete loss of power (e.g. unplugged, or power failure). When power is returned, the power button does not start the machine (no response). Initially, after a couple minutes it would work. Over the years, this symptom has expanded to longer and longer for the button to work. About a year ago, it would take a couple hours. Recently, this timeline is now up to 24 hours. Once the power-up succeeds the machine boots and works normally.
Obviously, something is decaying in the machine (probably a capacitor, but could be something else). I'd like to replace the whole machine - but just don't have the money. Anyone know definitively what might be the issue? I'd really like to know if someone has actually root caused a similar issue to exactly the component on either the power supply or logic board that would be responsible for the condition.
