I just noticed something cool on my white Macbook. I left it asleep for several days and when I tried to wake it, it wouldn't. I then plugged in the power adapter and pressed released the power button. What I was expecting was for the computer to boot as if it had been off. What happened instead was that the screen back light came on and the screen image re-appeared but was blurred. At the same time a progress bar appeared in the lower third of the screen. It slowly filled over about 10 seconds, and then the blurred image became clear and I could use the computer.

Is this new or did I just now notice it before?

The exact same thing also happened to mine when I re-calibrated my battery down to squat and left it overnight before re-booting. It must be the new normal.

Safe sleep. It was actually on the very first iBooks with OS9 and then they pulled it as it had a bug that could cause data loss and now it has come back with the MacBooks and pros.

Is there a way to put your MacBook into safe sleep intentionally? Like holding option when you click sleep or something?

It always writes the contents of RAM that it would use for normal sleep to the HD as well for Safe Sleep. So safe sleep is always enabled I guess.

Safe sleep has been a feature on the Powerbooks for the last year-and-a-half or so, and is automatically present on all Intel 'books.
