Hi All,
I have the above iMac which is an i5 - which seems to have a strange problem in that the Mac works fine, can shut down and restart - no issues - ( except for AHT fault code: 4HDD/30/40000005:SATA(0,0) ) - new hard drive about to be installed with OWC SSD Kit - but only if the mains power lead is left in and with power applied but if the mains power is disconnected - it will not turn back on - but will power back on as normal if left overnight unplugged - suspect iMac power supply maybe or could it be the hard drive ???
There is a very, very faint click from the bottom right corner of the main unit when it won't power on ??
Any suggestions or experience would be gratefully appreciated !!
