Hi everyone I love you all. I'm a semi newbie here so have mercy... I close my lid as I've done over the years with my PC laptops and if I open it a day or so later the battery is still fine. However on my shiny new 13 inch 2012 macbook pro this is not the case. I closed the lid many nights only to open it the next morning and battery has depleted. What am I doing wrong please? Can anyone advise me. Thanks so much.
