Hello,
I have an IBM R50 E with a Intel Celeron 1.4 Ghz processor installed with 10.3. Recently I discovered that simply loading the module p4_clockmod scales down the CPU-frequency to about 170MHZ and as needed scales the freq up. This helps saving battery power.
No it doesn't. Celerons don't have CPU frequency scaling. p4_clockmod only has duty cycle modulation (the same as throttling) which does not save any power.
Thanks, I found the settings I was searching for but since the CPU does not save any power this exercise is of course in vain.
