MacBook Pro A1286 not turning on anymore, did 10 sec power on nothing.I got a Macbook Pro (2008) unibody model A1286 Motherboard 820-2330-A. I do take al precautions knowing how thermal cycles...
Rispondi a "MacBook Pro A1286 not turning on anymore, did 10 sec power on nothing."I'm also worried any of the BGA chips might have desoldered. But as I've stated above i'm extremely careful about thermal cycles on laptops and this machine was fully optimized for airflow, in fact both fans were always running at 5900rpm. But I checked the nvidia MCP79 on the schematic cnnects with the SMC circuit and if it's desoldered might be bothering.. HOPE ITS NOT ! I don't want to reflow anything.
Rispondi a "MacBook Pro A1286 not turning on anymore, did 10 sec power on nothing."Hi thanks so much for answering didn't think it was going to be that fast. Three last digits from serial number it's 1 G A. Do you need anythin aside from this I can check up ? I did bridging the power pads but it's not turning on, battery charges fine. I checked the voltage on G3hot trace and it measures 3.4 . I'm suspecting the SMC it's screwed.
