- Power to the 68030 is turned on and off several times a second to reduce

- "Battery conservation" doesn't slow the computer down overall, since,
- unlike
- for processor cycling, the computer is running at full speed. When the
- slider
- is closer to conservation, the internal hard disk will turn off sooner,
- and
- the computer will auto-sleep sooner. If you're doing a lot of
- disk-intensive
- operations, the spin up/spin down of the hard disk will slow you down a
- bit,
- and may be more annoying. Choosing what a good balance of conservation
- and
- performance is will depend on how you use your computer. If you're away
- from a power plug a lot, you'll probably want to lean toward the
- conseration
- side. If you're usually plugged in, you might as well leave the slider at
- the performance end...
