MacBook shutdown on battery drain

[aswine]

My MacBook shuts down when the battery drains all the way down. I'm pretty sure back in the days of PPC lappies, they went to sleep before the battery died. Is it supposed to shut down, or is something goofed?

I don't know about you, but when there's no more power, the computer usually turns off. Maybe back in the day we had magic warlocks powering our computers...

Seriously, if you drained your battery *completely* the MacBook will shut down. Usually, the battery will show up as 0% but actually have a little more juice for backup purposes. Don't force it to use it all up, it will mess with your battery.

I've never tried this out, but according to this apple support page about calibrating your battery, it appears it would go to sleep.

When the battery reaches "empty", the computer is forced into sleep mode. The battery actually keeps back a reserve beyond "empty", to maintain the computer in sleep for a period of time. Once the battery is truly exhausted, the computer is forced to shut down. At this point, with the safe sleep function introduced in the PowerBook G4 (15-inch Double-Layer SD) computers, the computer's memory contents have been saved to the hard drive. When power is restored, the computer returns itself to its pre-sleep state using the safe sleep image on the hard drive.

My MBP has always gone to sleep when the battery's drained, when I charge it and boot it up next time it shows the grey Apple logo with a progress bar underneath, when it's done loading everything is exactly how I left it before the battery died.

I reset my SMC. That fixed it. Thanks.
