I use Speedswitch XP. I can run my I9200 Dell w/ P-M 1.8 @ "Battery Optimized" setting (which basically throttles it down to zero CPU usage @ idle
) and surf for 5.5 hours on battery (6 cell, 53 Watt Hours), with LCD brightness lowered.
I'll bet I could set the CPU usage limit, end all extranious programs, lower LCD brightness all the way, mute audio and squeeze another 45-60 minutes out of her.
So having been bitten by the "battery longevity luxery bug", I completely understand where you're coming from.
-Of course, I could have stuck with my old 133 MHz Gateway Solo 2300 if I could be happy with such limitations all the time.
But when I need that P-M to throttle up & deliver all of it's 1.8 gigs of joy (and it often does
), it's there on tap. I control the threshold, and it's easy to do.
Do the research and pick out the best CPU "dimmer-switch" program for you, and you'll enjoy the best of both worlds. You won't be sorry you paid for the "extra" .2 Gigs in your computer once you have this "thermostat" in place and you can finally enjoy a long visit away from a wall socket.
-But waddo I know, I'm just a nooby. However, I learned all of what I think
I know from this helpful forum.
