Re: help with POWER OPTIONS
The minimum and maximum CPU thing usually refers to CPU Clock Scaling. Your CPU runs at a certain frequency (for example, my Core 2 Duo T9300 runs at 2.5GHz). However, 2.5GHz is pretty fast, and if you're not gaming or doing other intensive tasks, much of that processing power is wasted. CPU clock scaling is a feature of mobile CPU's that allows the chip to run at a lower frequency when you aren't running intensive applications. Usually your system will automatically lower the frequency when applications aren't using much processing power. However, when you open a new application or need a quick boost of power, it will scale the CPU back up to full power. With battery settings, you can cap (usually by percentage) the limit that your CPU will run. This way, your CPU will never run at full speed and won't use up a lot of power doing so. The downside is that you're limited in power, as your processor is now running slower (usually around 800MHz to 1000MHz) so your programs may not load or run quite as fast. 800MHz on a dual-core processor is plenty fast enough to run web browsing, media playback, and office applications so you probably won't need that extra power when you're on the go. I recommend using the CPU scaling feature as it saves a lot of battery (I use it on my laptop when I unplug it).
