Yea, it's DIY Linux via pkgtools from Slackware. There's not too much else
to do. I use a new 2.6.21 kernel with all the acpi trimmings. I've been
using powertop on a regular basis. I've even gotten my wake ups down in the
130 range but acpi still estimates 32-33 watts of power. I wouldn't be
surprised if I've been running a faulty battery this whole time. Altho with
the first MBP I had, I don't remember it being any better. The real kicker
is, that when I deplete my battery, it takes hours and hours for it to
charge back up (when that worked). I also run both procs ondemand at 1ghz
all the time...
I don't know. I'm just cursed with power gremlins I guess. To be fair,
maybe I get slightly more than 30 minutes under load, but not much. It's
definitely under an hour at load. Maybe an hour 15 to an hour 30 at idle
tops. But certainly no more. I suppose I could try and get used to bumping
the screen brightness down. Maybe turning off automatic KB backlight in
pommed.conf (cause that doesn't work worth a crap anyway).
This all boils down to Linux kernel implementation as far as I'm aware.
Again, like I said earlier (or on another thread), if your not using an OS
designed for this particular machine, it's a crap shoot. Hopefully we'll see
some advances linux side with acpi. Hell, even getting suspend to work
reliably would be nice.
hi Jon. i've got my wakeups down about 130 as well running Debian Etch on m
15" MBP C2D, but can't seem to get my power consumption lower than 28-29W.
that gives me about 80-100 minutes of battery power, depending on whether or
not i roll another kernel or just browse the intertubes. other than
learning, is there any other reason you use DIY Linux rather than, say,
Debian, Ubuntu, Fedora, etc?
which Apple laptop do you have?
