Q: Early 2011 15" Macbook Pro Crashing Unexpectedly When Unplugged
Hi --
This has been an ongoing issue for the past year or so.
It began crashing exclusively while watching videos. I went to the Genius bar about 4 months ago and confirmed it was not due to a faulty GPU like many other Macbooks of this generation. During the tests run at the Genius bar however, they found OS software corruption, and repaired it accordingly. Much to my delight the issue appeared to go away.
About two months ago I replaced the factory 4GB of RAM with 8GB of high quality Corsair marketed for my given Macbook. About a month ago the shut down issue began again. It began as it was before, starting occasionally when streaming videos, with increasing irregularity -- until now (which unlike before) it shuts down when I do anything of somewhat processing intensity. Anything more than handling emails and a crash is expected.
Unfortunately the crash logs don't seem to hint at what might actually be causing the shutdown. Makes me think it could be a severe hardware defect, however the previous software fix seemed to offer a brief cure before. I expect my HD is coming to the end of the life, as is my battery. More likely than not it is the battery, which is in the "Replace Soon" label and has served a whopping 1381 cycles.
I was planning on replacing the HD with an SD in the near future anyway, however some verification on what might be the source of the issue would be much appreciated, so that I don't sink money into a battery replacement only to know there is a bigger issue at hand.
Here's the system.log file (I believe the crash occurs at 16:18):
