Hi there folks!
as i'm pretty new on mac computers, i had the idea of writing my problem down and posting it in the forum here, in hope to get some advice.
here's my story/problem:
recently, the macbook pro 15" (late 2008) of my girlfriend refused to charge with the "usual" 85w magsafe power supply which she was using for the past years. so, symptoms here are: no orange or green light, not even a dim green light as some users report, just nothing at all.
because i'm a self-repair-guy and a computer technician (usually building or fixing windows-pc's, hardware and other stuff), i thought i could give it a try and fix it myself.
so first i thought, there might be an issue with the power adapter itself. so i swapped it with a working one of a friend who has the exactly same macbook (his powersupply was working on his macbook), hooked it up, but still nothing.
alright, my suspicion was growing that there was something wrong with the macbook itself, but let's continue.
surprisingly, the macbook could still run on battery for a few minutes!
next step i tried was to swap my gf's battery against the newer (and fully charged) battery of my friends macbook, and voila! the macbook was running fine for 3 hours and i was able to do a complete timemachine-backup.
so, the mbp itself runs just fine, it just won't charge the battery or run on the powersupply itself.
so, all leads to the conclusion, that there's something wrong with the macbook-internals, likely with the dc-in adapter or worst case: the logic-board.
i've read a few topics of people who had a dim green light on their magsafe power adaptor and a few of them tried an smc-reset and were able to solve their problem. i gave it a try myself, but no luck in my case...
in my opinion, it has to be some kind of fuse that got blown, right where the power goes into the mbp. otherwise, it wouldnt run fine on battery power.
as you see, its a pretty old mbp, but we dont have much money left and it would be great if there was a way to fix it without replacing the whole logic-board or buying a new macbook.
does somebody got an idea or even a fix on this issue? has one of you guys had the same problem?
or does somebody have some kind of circuit diagram of the mbp late 2008?
thank you guys in advance for your help/inputs.
and sorry about my english, it's not my first language.
