Amongst the complaints I recently shared about my MacBook Pro was its tendency to slip into a coma. A reader shared the suggestion to change the MacBook’s power management settings such that the contents of memory are not saved to disk on sleep.
I did so, and man, hallelujah! Well, sort of. While flying home, my first battery ran out of power, so I did my usual Powerbook routine of sleeping the notebook and swapping batteries. Took me about 10 seconds total. And, when I opened up the laptop — nothing. The notebook was powered down.
Now, with my Powerbook, that never happened. Upon re-opening, it powered back up beautifully. With the MacBook Pro, however, I would open it up and it would be off. But, when you hit the power button, the contents of memory would be reanimated from disk. And, if you were lucky, you’d get back to work in a few minutes.
After changing my power management settings, however, you guessed it! You lose suspend-to-disk for memory and for whatever reason, the MacBook does not keep the system in sleep for any fraction of a second when you swap batteries. Add these two factors up, my friends, and you get complete data loss.
There are some who say, “Nah nah nah, I always save my files before sleep, what kind of idiot are you?” Of course I saved my files before I swapped batteries, but man, I sure miss the good ol’ days of the Powerbook just working. If only it weren’t slow as molasses…
