Q: late 2011 MBP shut down
hello all,
i have a late 2011 mbp, 10.9.5, that has started shutting down when off the power cord. i can put it to sleep and move it about and re-plug in, so the shutting down is not immediate. my battery is the original one, but the sys info app says the condition is normal. i have reset the PRAM and the SMC, this seemed to work, but did not for more than a minute or two.
question: even if the sys info app says battery is normal, can it be wrong sometimes?
(an aside, apple just 2 weeks ago replaced the logic board under warranty. i don't think it's connected, but may be.)
i'd be happy to buy a new battery (like the newer tech one) and see if that helps, but with the sys info app saying battery normal, i don't know if this would help. thoughts? pasted battery report below(why o why does pasting from the sys info app not work??):

I have a Late 2011 MBP as well, and I've replaced the logic board myself not long ago.
AND I then had to replace the battery as well...after some issues.
I suggest you replace the battery, it MUST be fried at this point.
By fried I mean old, way way old.
Genius Bar can do some specific tests, that WILL fail if the battery needs replacement.
That's the only way you can know for sure...
