Intel-undervolt: CPU undervolting and throttling configuration tool for Linux

In 2006, I had my first laptop right before the release of Windows Vista. Unfortunately, running Windows Vista makes my laptop hot and the fan kicked in to make a lot noise. I cannot remember the software's name which can reduce the core voltage of my single core Centrino processor. I was successful to undervolt the CPU to the lowest possible voltage. That cools down the CPU by a large margin, the laptop became quiet again (also stable). I was happy. The functionality disappears with the newer generation intel CPU releases, I had not been able to do similar thing ever since.

Back then, Intel had the best semiconductor process, and they had a wide margin on undervolting the CPU.

I don't know about undervolting, but ThrottleStop allowed me to run my 230W laptop off a 65W power adapter by downclocking the CPU to 800MHz!

Did I get that right? A laptop that needs a 230W power brick and wasn't really intended to run on 65W, though it does? 800MHz, that was what we had in the 90s, I assume that's the era? Meanwhile, my laptop is idlying at ~9W playing YouTube. Crazy.

How long did the battery last? Less than 30m I assume.

Most 230W laptops were not meant to be run without power brick. They were more portable desktops than laptops. Even sold as such.
