Reducing Power usage

[ANNR]

I only use the laptop to take notes when it is not connected to the power core so i don't need all the processing power the cpu offers. Is it possible to set the components in my laptop to run at minimon power if not lower when not connected to the power core?

EDIT: How do i go about under volting my laptop? does it have any side effects to the laptop? Like will it reduce the life of my laptop? I don' think so but i just want to make sure. It does not matter if my laptop will only be useing 5% of its CPU's processing power after undervolting as long as it goes back to normal when the power core is connected

Thanks

When you say undervolting, I assume you mean the processor? I mean everything is made to run at specific volts. Most processors only run at about 3.3 volts(not 100% sure about laptops) But obviously, you can't drop that too much. Plus, I can't see droping .1 volts really achieving much

I run SpeedSwitchXP and keep my laptop locked on 800MHz(Max battery). It really helps with heat and battery life.

i've used speed switch xp too, it seems to help a little bit, if nothing less it keeps my fan from kicking on and off on my dell. Stupid thing drives me nuts, it kicks on and off about every 30 seconds.

It really helps my laptop. Besides also having that kind of fan problem, people would complain they couldn't get more than about 1 hour out of the battery. I can EASILLY get 2 hours from my battery, and it's over a year old. Plus I use the battery a good bit.

3.3 volts? Most fry at 1.8 or so, and stock they are usually under 1.4V.

It's a mixed bag, really... But you are correct, I just found more current processors run at 1.6 core. However, some of the really old ones(8088 on up to earlier pentiums) run at 5!
