| Thank you for the info Only laptops I've used for more than 4 hours are a Compaq Celeron 2Ghz and IBM Pentium 4 1.5Ghz; neither one required me to look into lowering power usage, as I was using them hooked up to power outlet 100% of the time.

| The software shows no difference in setting than what my laptop already provided. For the dual core T2060 lowest CPU voltage is 1.025 remains unchanged. I believe what it does is to lower the 1.215 volt at highest multi (cpu default) and see if it runs stable. So, if any battery saving, it is at high performance defeating the purpose.

| Surely, if I want to stay at Starbuck outdoor in hot summer day for another hour longer because I want to look at the pretty half naked girl sitting next to me, either I switch the laptop at power saving mode and careless about high power setting at lower CPU volt There is no need for max power mode just for browsing the internet. I don't doubt the ability of the software. I was able to use mine for about 4 hours as is. However, I am not quite sure lowering 0.05 volt on every step of multi will benefit much since the lowest CPU volt remains unchanged in my case.

| Testing and looking for lowest CPU voltage high performance setting. Will post some photos later.

| Exactly. Speedstep has lower voltage settings available that it does not use, but NHC will allow the user to select. In this way it will work on any Intel Speedstep or Enhanced Speedstep capable CPU, regardless of laptop brand. Pentium M 2.13MHz Default 16x @ 1.356v ~73c 6x @ 0.998v Modified 16x @ 1.180v ~56c 6x @ 0.700v ~35c I had to re create my NHC profile, so I just retested the above. Huge difference in battery life & temps, not to mention the fans are again silent. |
