When you work in console, the clock frequency of your cpu will not be such important to the speed.
How this is done, I cannot tell. As I am using X, my first choice is powerdevil, which is X related. Maybe someone else can tell, how hold cpu clock down in console. I think, it might be a command to the /proc interface. This will save some extra power. In BIOS all not necessary interfaces can be switched off (also the gprs interface, which might save extra power, too) Another thing is, to deinstall all not needed services. Some services, like snort or virus scan, do need some cpu power. Yes, and java might increasing cpu power was well. I suggest furthermore, to deinstall all packages, you do not need. Remember, every service or process, you are running, might need extra power. Ah, yes, one thing may also save power: You can switch off all logging, or do all lojgging to an SD-card , RAM-drive or USB-stick. Doing so, you can inhibit permanently writing to the harddrive, justonly when you need it. If you do not need logging at all, just switch it off. If you do so, you can switch off the harddrive, which saves power, too. When you want to write to the harddrive, there is a short delay, but this will not bother, I think. > Or is what I'm doing now about the best you can do?
