Title:

Power Supply Change No Go!

Text:

I sat at my Mac recently, power button depressed... NOTHING! I tried the power cord in my old G5 IMac, came to life straight away! I deduced that, (as there were no fans, lights...zero signs of life) that it MUST be the power supply, so I purchased an ifixit power supply kit, performed the surgery required... and NOTHING again!

Given that this is my main (business) Mac, approximately 2.5 yrs-old, and that I always keep it plugged into a UPS, I would have expected the logic board (which I now deduce to be dead) to have lasted way longer than this! I've been a professional Mac user since the grey boxes of the 90's, and always found them to be rugged workhorses, but finding my trusty $1,200 Mac inexplicably lifeless is giving me a huge trust issue!

Given that my power supply fix failed, and the logic board is therefore the issue, I've been told that I should 'bake' the logic board (yes, in the oven!) in an attempt to re-flow the solder... does anyone know if this actually works?
