Sleep awake failure and restarts. Is it related to power supply?
When my iMac goes sleep it won't wake up, instead it will restart.
I have tested it with different OS's, HD's and RAM modules. I have also replaced the CMOS battery, still no luck.
Now I am going to buy a power supply and give that a try. What would you say?
Does anyone knows if power supply could be the source of the problem or nothing got to do with it.
Thanks for the help in advance!
P.S. - Everything else works way it should.
Finally I have replaced the power board but unfortunately it didnt fix the issue :(
I guess its related to logic board .
Ist dies eine gute Frage?
