I just discovered this fantastic piece of software from rightmark that allowed my battery to last longer per charge and also let the netbook run far cooler.

Let me show you what I did to my 2-in-1 dell netbook model 3147.

Step 1: Rightmark Processor Power Management (PPM) Panel.

This freeware software allows for the throttling and tweaking of CPU voltages. My netbook had the annoying habit of running at 100% CPU especially waking from sleep mode. This neat software package fixed that issue for me!

Step 2: Enabling Throttling.

As highlighted in the screenshot, that feature needs to be set to ON. By default it was off.

Step 3: Enable Idle.

This has to set to ENABLE IDLE. The default again was off.

Step 4: Optional: a Little More Speed in Power Saver Mode.

While sipping battery power, initially the software slowed down my netbook but not worryingly so. To speed it up a bit, the increase threshold needs to drop from its default value of 90% to something far lower. I choose 30% for a good compromise with power savings and responsiveness.

So that's it! This is how I made my netbook last far longer per charge!

Question 10 months ago on Step 4

I installed this software on a good old nx9420 I still have at hand, which I've more or less recently upgraded to Windows 10, but quickly uninstalled it. To be honest, all I saw in this software was far from being what I really wanted, which is tuning the CPU voltages (undervolting) to achieve far less power consumption and heat generation.
In the past, when running Windows XP, I achieved this using Notebook Hardware Control, which allowed to set CPU voltages. With it I found the lowest possible voltage at which my CPU remained stable while running heavy CPU loading software, even in less than ideal conditions (by somewhat blocking the fan exhaust vents); then I raised that value a voltage step, and set it as my maximum CPU voltage, while also lowering proportionally the remaining multiplier step CPU voltages down to the minimum CPU frequency whose voltage couldn't be lowered (at 0.95V). This worked in an absolutely wonderful way.
So basically this is what I want to do, period. Up there you say "this freeware software allows for the throttling and tweaking of CPU voltages", but how do you tweak the CPU voltages? All I am expecting to see is a table where I can set the CPU voltage for each multiplier frequency step, is this possible with this software? This is what really works and can substantially lower the CPU power consumption and heat generation even in full load situations. The remaining stuff is… @#$%, to be honest.

Thanks in any case.

Note: Notebook Hardware Control was never made compatible with 64-bit versions of Windows, an application driver thing.
