Computer not recieving power from battery, Magsafe lights not on
I have been dealing with this problem for sometime now. I have a 2007 macbook, that wont power on. The last few days it has only functioned while plugged in. Today the magsafe lights don't turn on and the battery still has a charge, but the computer wont power on. A similar experience happened several months ago, the computer would not charge for several weeks, and then i plugged it in again one day and it just randomly charged again, and has worked fine since then. Any help you can give me would be great.
Use a multimeter to test out the Magsafe adapter. Here's the pinout on the right side of the page. It could also be your DC-IN port or a combination of the two. So test the adapter first. Press the button on your battery to see if it has a charge, you could have battery problems or battery connector issues. Next remove the batter and adapter, press and hold the power button for 5 seconds, reattach the adapter and give it a try. Let us know your results and we can go from there.
