Mac will not charge, or connect at all
Ive had my Mac for a couple years now, without any problems until a month or two ago. It began to stop charging. The magsafe would not light up at all and id have to pull it off and put our back in over and over, with a little tweaking and adjusting to get it to connect. two days ago it stopped completely. no matter what i try, i cannot get the charger to light up and charge. my computer is now completely dead with no hopes of coming back to life. i have also tried other chargers on it--nothing. no light, no sign of any connectivity. i have also tried swapping batteries for a functional one. the functional one in my mac did the same as my original one--nothing at all. my original battery in a different mac connected and charged up fine. so it is not my battery or charger. i dont know what to do now or what it could be. some research has pointed me to a possibly dead dc inboard? any info, insight, suggestions or ideas would be gladly welcomed. oh, and i do not have the option of taking it to a store, due to my current location. i can only order parts and attempt a repair on my own. thanks!
Is this a good question?

Try removing the battery and main's power - leaving overnight. You may need a new battery. I'm not familiar enough with this model to remember if it uses a "backup aka CMOS" battery or depends on the main battery and a capacitor... but - a failing backup battery might be a cause for this behavior. Also a cracked battery could be possible. I had a MacBooAir with very strange battery/charging behavior. Turned out the battery was damaged (cracked) but the crack was not visible until I removed it from the laptop and examined it. I believe "flexing" the case (picking up the laptop by one end) caused the problem. A new battery stopped all the craziness.
