Magsafe port failure diagnosis and replacement
I have a MacBook Pro 15" Unibody Early 2011 model A1286. Last night I noticed that the light on the Magsafe head wasn't coming on the the MBP wasn't charging. I went to the Apple store to test a new Magsafe power adapter and the problem persists.
The laptop is experiencing no other issues. The part is rather affordable but I haven't looked at difficulty.
Based on the symptoms is it safe to assume that this is my problem?
Is the repair on this expert level?
