I am not a Linux guru. I seem to have a similar problem with my
Sony Vaio PCG-FX140 (which has the same processor, PIII 700/550 MHz with
Speedstep). I am running SuSE Professional 7.3. In my case, it starts
at 700 MHz, but if there is a lot of idle time, it drops to 500 MHz and
cannot bring the speed up to 700 MHz unless I reboot. I don't think this
happens if I turn power management off from the BIOS.
A couple of weeks ago I contacted emperorlinux. They advertise in
linux magazines and claim to offer turnkey laptops with linux and
windows installed. They told me that apm will NOT work on most laptops
(apm -s will work on any laptop but most computers cannot not wake up
afterwards), and that the linux new power management is not up to speed
yet, but soon will.
So, it seems to me linux does something with speedstep but I don't
know what. Or is it the BIOS that takes the initiative to lower the
clock speed and linux cannot tell it to raise it back up?
