Right, im need to take my Macbook into my local Apple Store because my battery in my Mac says for it to be Serviced. However it keeps on going from normal (not saying this message some times), and then another time is just says it needs to be Serviced; 'Service Battery' under the Energy Saver Tab in System Preferences and in the Battery Menu Bar. So how would i go about doing this? I'm still under my 1 year warranty so i believe that i can get them to replace my battery for free as im still under warranty. Do i have to make a Reservation at the Genius Bar? Or can i just turn up with my Macbook and say i have a problem. The thing is that the next reservation I can get is not until the 28th in the Store where i live and i kinda need to sooner to be checked and replaced. So basically, my battery isn't right... and i need it to be replaced! Can i just turn up? It's Urgent! Any ideas?
