Americans advising on saving power.

One quirk of OS X is that the “better battery life” settings within the power manager will be more efficient than if you were to apply the same exact settings manually. Conversely when you need more power (like back at your desk), the “better performance” setting performs better than if you set it manually.

Has anyone else had this experience?

yeah because manually you can only control the screen and hard drive.

when you use better battery life the processor is affected

Yea, us Americans are the only ones in the world using mass amounts of power and destroying the environment. Everyone else is trying too hard to fix what us Americans are doing. Give me a break.

Off-topic insult-slinging aside...

I can manually control my processor too, not just screen and HD: the processor can be set to Auto, Highest, or Reduced. So if there's a difference between manual vs. preset Settings, I don't think that's it.

(This is on a 15" Al PB--older models may not have the same controls.)

G4 iBooks have this too -- to the poster who said he/she didn't have it, make sure you looked in both of the tabs within the energy saver preference -- it's located on the second tab, and not on the first tab (the first tab is the one that has display power save settings).

I have always run on custom because I change the display and hard drive timeout settings, and this automatically bumps me to custom profiles. So I guess I get any advantage that I supposedly would get? But I'm suspicious of this claim somehow....

Maybe, but getting a couple of spare batteries gets the longest life! I love the warnings you get about "your computer is on reserve power" and then seeing how long they will run for...yep, custom settings work for me, but Airport and an iPod shuffle nuke the batteries.

<OT> I have two TiPBs, only one charges off the mains, the other falls over as soon as you plug in the charger, but will run happily on batteries...any ideas?...motherboard fault or what?..tried switching mini power board and sadly no change.

PS If you guys paid our gas prices, you'd probably have had a revolution by now. :D

Hehehe, yeah. I thought it was funny that one of the suggestions was not to run Photoshop or other intensive apps. Well, duh, your battery will last longer. But are you a slave to battery life, or are you trying to accomplish something with your 'book??? :rolleyes:

Yeah, but if you're going to bring out your laptop and not work with the proc intensive stuff you need to do, then you may as well keep it in the bag.

His advice wasn't stuff that any of us didn't know already. Keep the screen brightness down....haha, thanks! :p

Anyone know exactly what the Auto setting for the processor does?

Thanks :)
