power supply

Hello all, I'm breaking this case open again because I simply don't have the needed experience to do anything about this on my own. Here's a refresher-- A couple years back while working on an Apple II I had acquired, I managed to fry something somewhere. The machine was on, and I had...

Macbook 13inch mid 2012 Running on Yosemite 10.10.05 Despite what I do to my power settings my macbook will shut completely down when plugged in after about an hour. But will stay in sleep mode for days/ until it runs out of power when not plugged in. Seem like something is backwards here...

I might have a stupid question but in need to ask it anyway. I've been experimenting with the possibilities of using parts not specifically made for a certain generation of macs. For example, I upgraded my iMac 2009 with a CPU and GPU for the 2010 model. (i5 2,66 became i7 2,93 and Radeon 4850...

Lightening hit by the house and iMac won't boot at all. I've diagnosed it fairly well, I'm down to the power supply or Logic board, but which one? With the diagnostic lights I get the first one meaning I have constant power from the power supply. When I press power button no second light. I've...
