Won't power on with charger or battery
A while back, my Macbook stopped powering on (after going to sleep). There's no boot whatsoever--no fan noise or anything. I took it to the Genius Bar, and they wouldn't touch it because it was "vintage." I replaced it with a Macbook Pro this summer, and it's sat on a shelf since then.
Fast forward to now, and I'd love to get it up and working again for my kids to use for Minecraft and some web-based games. Basically, before I order a new logic board, I'd like to make sure I've exhausted my troubleshooting options.
This is what we've done:
1. Tested it with and without battery. The Magsafe adaptor glows a bright, solid green.
2. Reseated the RAM.
3. Taken the case apart and checked ribbon seatings.
4. We checked the power pads with the multimeter and they weren't getting a reading at all. I cleaned the terminal on outside of the case with rubbing alcohol, and now we're getting 0 and 3.42. (That all being said--it's possible my husband was doing the multimeter wrong.)
5. Bridged the jumper pads to short it and start it up.
It's an A1181, by the way.
