i came home to a completely dead tbMBP. My new baby! I thought it might have been my power strip (MBP plugged into LG monitor plugged into strip), so i've got it plugged into another outlet now. It was working last evening, so not sure when this happened. Not a peep out of it. For a completely discharged battery, how long should it take before theres enough power to start up? Im terrified its more than just a discharged battery, I need some reassurance.
