Do vista power settings on laptops affect just the screen brightness and when it turns off, or does it effect performance itself, such as the processor speed? If they do affect processor speed, by approximately how much (i.e. a percentage).

I'm running a dell xps 1330 with 2gb ram and 2.2 Ghz processor.

Thanks as always,

On computers that have processors with SpeedStep (Intel) or Cool'n'Quiet (AMD) it will clock down the CPU when not under load. It can also power down hard drives, etc. It will not slow a computer down in regards to performance.

Edit- You want max battery on your laptop though and having the higher power setting over performance will keep your laptop cooler as well.
