I have a Sony VAIO VPCEB34EN laptop with i3-370M @ 2.4 GHz Processor. I replaced my worn out battery with a new one. The old and current battery both have the same battery life of 2 hours only. I mainly do browsing or movie watching (three USB ports are connected with mouse, keyboard and data card/dongle always). So, I want to underclock my CPU as much as possible without affecting performance to gain battery life. Can anybody guide me through the whole process, as I never did any overclocking/underclocking in my life? Also, list the gains/losses I'll have after underclocking.

With passive settings, the CPU voltage and multiplier are reduced before fan speed is increased to max in the event that the CPU begins to approach "hot". With active settings the fan will go full speed before the system makes reductions in CPU settings. Any time the fan is full on, the battery is quickly draining, unless connected to AC power. These settings can be set differently for when you're on battery or AC power as well since when on AC power, consumption isn't as much of a factor.
