I just got a brand new Late 2011 MacBook Pro, I Was wondering if it continues to charge past 100% meaning if I leave it plugged in all day long, then use it for 1-2 hours on batteries will the battery deteriorate fast? ( loose captivity fast)
Also when the battery is done charging, does the MacBook Pro run off the power addapter (no power going to the battery)
Thanks Kyler

No. I do that all the time. In fact, that seems to be the preferred method according to Apple. Read this: http://www.apple.com/batteries/notebooks.html

yes.

Also of note for those who think this is "odd" behavior ...
When my MBP is plugged in and the battery is charged to 100%, the battery level will slowly drop over a week from 100% to 95%, then recharge when it drops below 95%. That seems quite normal, as it saves the battery charging circuits while it runs off the house current.
Thanks that answers my Question 🙂
very welcome, also to support steve359's excellent point: http://support.apple.com/kb/TS1909
Glad to help
I have another question; I downloaded SMC Fan Control because my MacBook Pro hits 200 degrees Fahrenheit when using graphics intensive programs. Can I damage the fans if they’re maxed out for a couple of hours? Or can the MacBook Pro Components handle these temperatures? That’s a lot hotter then my PowerBook G4 got.
Thanks Kyler
Like any mechanical device, if you operate it to its design limits (or more) it will wear out sooner. The MBP has internal sensors that when determined temperatures are reached it will automatically shut down so as to prevent damage to the MBP.
Ciao.
So is it a good thing that the macbook pro runs off the power adapter or bad? thanks.
Is it bad to keep my Macbook Pro charging all day long
