Power on intermittent on iMac 27" mid 2010 EMC 2390
First time today, tried to turn on my iMac and no power, no beeps, no nothing. Unplugged all USB devices, still nothing. Unplugged the power cable, waited 30 secs or so, plugged it back in, waited another 20 secs. or so and it powered up.
Shutdown, then pressed the power button, it came right on. Shutdown completely, waited about 5 mins. and tried to power back on, nothing. Unplugged for about 30 mins. Plugged it back in and it powered right up. Is this a sign of the power supply maybe going bad or could the power button be the issue? I'm not sure by clearing the SMC solved anything.
Is dit een goede vraag?
