Hello,
I have a presario 720au laptop (only has acpi support),
and I am trying to work out why it's
running time on battery is so low under freebsd.
Under linux and windows xp, I can get up to about 4 hours of battery
life, while on freebsd (-current, compiled jul 9), it's less than two
hours (closer to 1:45).
Is there something fundamental I'm missing? Both windows xp and linux
seem to run quieter/cooler (I assume they are turning off fans, idling
the cpu, etc), but I cannot achieve the same effect with freebsd.
I've attached a dmesg, if that's of any help. All the OSs are pretty
much stock standard installs with no tweaking. Linux is 2.4.21 +acpi
patches, and freebsd only has nate's EC patch (which has since been
committed, iirc). I've tried using my own compiled dsdt/aml table but
that doesn't seem to change anything.
If anyone can point me in the right direction, or give any other
information, it would be appreciated.
thanks
