Just got the machine back. Apple gave me a "CS code" or something like that due to my continued problems getting the issue fixed. Local place couldn't reproduce the problem, so they sent it in to Apple. Apple replicated the issue and replaced a whole bunch of things. Audio board, Magsafe/power board, both fans, heat sink, and the top case including battery. They said that the power board and battery were causing my problems.
No charge..... computer is out of warranty for everything but the logic board, so that was really good of them. I fully expected to be charged when it wasn't related to the logic board.
Have it restoring from backup now. Might be done by the morning at this rate. Don't have my network adapter with me, so it's restoring over wifi.
