Macbook pro power supply issue

[artificialaxiom]

Earlier this morning, I was using battery power until the power drained quickly and unexpectedly. Once it shut down automatically, I could not turn it back on. It does not run on AC charge or battery. The mag-safe light is only a faint green, and I have reset my PMU. I'm hoping to not have to take it to Apple as it's warranty ran out about two months ago.

I don't know how old your computer is but if the battery is removal, try starting the computer with the battery removed. If it starts, it is probably the battery.

Try to borrow a friend's power adapter and see if that works. If not, it sounds like a bigger problem that would require repair...
