You'll simply notice a delay of a second or two next time you turn it on, while main memory is being restored. It's like the hibernation feature in Windows, and the TI-84 CE appears to do something very similar (it even shuts down the realtime clock, meaning you'll have to reset the time and date if the 84 hasn't been used for a few days).

This sounds fantastic, but this comment by piu58 seems to suggest that not all of the RAM is backed up to the flash:

"If you run a program which need some time for calculation, and you don'*t wait for the result, it may be your results are lost. The calculator switches off automatically if not used for a period of time. The cg20 stores information as long as battery life."

I figured with a hibernation feature, RAM, CPU cache and the current memory pointers would all be copied from flash so that nothing at all would be lost, including the current progress through a long calculation that is in RAM.
