Hi,
I updated my (old) laptop from FC1 to FC2 yesterday and after the usual problems with the pcmcia cards and networking, I've noticed something strange.
I monitor my CPU and ethernet usage with gkrellm and I've noticed that my computer is running at about half the speed it should and the clock is running at about twice the speed it should.
The laptop is a IBM Thinkpad i1412 with 512MB Ram and a 366 MHz Celeron. gkrellm says its running at 182 MHz. I've added the acpid and enabled it in the grub.conf with acpi=on. The battery monitor doesn't work either, and it used to in FC1.
I've poked around a little, but my ACPI knowledge is limited. I've noticed that my /sys/devices/system/cpu/cpu0/ directory has no sub-directories. I gather this is because I doubt this hardware supports this kind of thing.
Any suggestions? 366MHz was just usable for what I do, but 182MHz is unacceptable.

My 1.6GHz Pentium M based IBM Thinkpad T41 runs at the minimum 600MHz most of the time because the processor is mostly idle. The cpuspeed service monitors CPU usage, and kicks it up to the higher levels if it is needed. If I am building something large on my laptop, cpuspeed kicks it up to 1.6GHz. My battery gets eaten much faster, temperatures rise, and the fan blows at full speed.
If you really don't want cpuspeed to manage your processor, you can disable it with:
service cpuspeed stop
chkconfig cpuspeed off
cat /proc/cpuinfo Use this to verify your current speed and processor features.
