Computer will not turn on
I have read about this and the info from Apple but when I go to the trouble shooting it describes looking for diagnostic LEDS. I don't believe that my model has these as my disassembly take the front off not the back as the pictures show.
My computer was working then one day it was off and I can't get any response (power) at all. I have read about power supply and motherboard issue but don't know where to start. Is it worth trying to replace the power supply ($140)? Is this the right first step?
Is dit een goede vraag?
