Hi, I have a 2010 13" MBP that will shut itself off instead of going to sleep when the battery is drained. I tried recalibrating and resetting the SMC, as well as disabling hibernate, but the same thing happens. The computer is barely a month old. Anybody else with a 13" experiencing this? I posted this issue on the Apple forums and someone replied stating that they heard Apple is looking into it, but usually occurs with i5 and i7 machines.
