hi misc@,
having OpenBSD 4.0 installed on my ThinkPad A22p (dmesg below) and
wearing the appropriate oBSD shirt i'd like to ask whether it's
possible to get max speed from this notebook without having the
battery built in.
i booted without it as i don't need it; i use this machine as my
energy saving workstation for lightweighted tasks (email, browsing the
web, etc.).
however, running connected to the power supply and without battery i
get this:
# apm
Battery state: unknown, 0% remaining, 0 minutes life estimate
A/C adapter state: connected
Performance adjustment mode: manual (698 MHz)
with the battery built in, i get 1 GHz. trying to set the speed
manually (apm -C or -H) is 'ignored' without error message -- it
keeps running on ~700MHz.
any ideas?
Have you tried BIOS settings? I have an old T22 900MHz P3 and I can
disable CPU throttling in BIOS, which seems to take precedence over the
OS settings. I'm running 3.9.

thanks,
being an old non-x86 guy i (unfortunately) quite often ignore the fact
of a BIOS on peecees ;)
okay, setting CPU speed selection from automatic to maximum didn't
change. however, there's another switch to disable CPU power management
-- maybe this will override it. i'll try it next reboot (am not able
right now due to some tasks) and report back for the archives, if, and
how, things went.
thanks again,
timo :)
