Hi,
I've got a MBP Unibody from, perhaps, 2009. It might be this model:
OS is 10.6.something.
I was using it yesterday without the magsafe adapter, on my lap, when I adjusted the screen a bit and then it went dark. This has happened maybe twice in the past and I've been able to get it going again after letting it rest a few minutes, then plugging it back in with the magsafe adapter, and pressing on the power button. So last night I did the same thing.
It restarted fine but I noticed that the light on the adapter was not lit up properly - a faint green color did show up. And of course the battery was not charging.
I tried another adapter, no go.
I used both adapters on another macbook and both worked fine, bright green. So I'm guessing it's not actually the adapter's fault.
I did a few things to try and remedy this:
a) I powered down and then powered up again.
b) reset the SMC
c) reset the PRAM
d) ran applejack (just for kicks)
Then I clicked at the top right on the battery icon to see this message: "Service Battery".
My MBP is no longer covered by Applecare and so I took out the battery just to see if I could power up the Mac to get some of my files before taking to a mac surgeon. It won't power up without the battery at all. I've got about 25% life left in the battery. Does anyone thing that this is just a matter of getting a new battery??
Thanking you in advance........
