Dead Battery

My Problem

My Macbookpro would not power on. The charger was constantly Orange.

My Fix

I replaced the battery with a new one(which took all of 15 mins)and it fired right up!!!

My Advice

My advice is make sure you read the tutorials on the ifixit site. Go through it in your head what you want to do. After you have read them and have a clear understanding of the work involved, then start.
