Underclocking CPU on Laptops

[niggles]

Hi All,

Just wondering if anyone can tell me if it is beneficial to underclock my Inspiron 6000 if not running off the battery. I understand it puts less stress on both the CPU and memory and therefore makes it last longer, but I'm not too worried about that. I have a Vantec base cooler that drops the temp by about 4 to 5 degrees which I'm confident will help with heat. I'm most concerned about making the battery last longer than 5 years assuming that I don't actually run it off the battery at all.

The power goes directly to the notebook and bypasses the battery.

Battery life will not be affected much when on A/C.

I would not underclock when on A/C, and instead would force CPU to run at full speed all the time when connected to A/C power. Also, undervolt CPU at all times (stress test to confirm stability at desired lower voltages). This combo allows P-M to run very cold, and using fan control, fan will be off most of the time, even though CPU is at full speed.

Lower voltage = lower temps = longer life for all, plus quieter operation.

Using Centrino hardware control for CPU speed and voltage, along with I8kfanGUI for fan control.

Good luck in trying to get your laptop battery to last for five years!

Lots of heat does reduce battery longevity. If your notebook runs over ~55C when on AC, I would let it underclock.
