 |
|
OK, I've been fighting this one for a bit, and I'm just not getting anywhere. I've got a dell inspiron 8600, and I'm running gentoo done with the stage 1/3 install using very conservative settings for now. Everything works great, but I have a real issue with the ACPI.
First of all, I can get a full 4 hours or a little more of battery life when I run windows. At best, I can get two and a half in linux. I also noticed that the laptop tends to get a little too warm in linux, and it makes me nervous enough that I had to switch back to booting windows as the default. When exploring the causes, I did notice that speedfreq does scale the cpu correctly, but it jumps up to the full 1.6GHz if I execute anything at all, and then it doesn't come back down afterward. I'm betting this might be related to the battery life and heat, but I'm not sure. Maybe what I'm after is just having it set at a fixed 600MHz on the battery--I think that might be what windows does. I also know that windows powers off the lan card and such when it's on battery, but I don't know if gentoo is doing that or not.
I've read all the how-tos and things I could find, but I just barely finished my bachelor's degree, and my mind is a little fried right now. From what little of it I can actually understand, everything seems installed correctly, but I want to make sure before really making the switch to linux on this machine.
Does anyone have some experience with getting all the power management problems smoothed out, especially with this model? (I also need to get the suspend working, but it's not quite as important as getting rid of the heat problems and making sure the battery isn't drained so quickly.) |

did you enable support for the cpu to be able to change speeds?
I think its under where you select what type of CPU you have in your kernel config. Or in the ACPI portion...one of those two.

|
Looking at this, maybe what's wrong is the # CONFIG_X86_SPEEDSTEP_CENTRINO is not set. I'll try that and see what happens
In the mean time, I should also mention that when I try to run speedfreq in any way (change policies, view the status, or even see the version or quit) it does nothing at all. Just gives me back the prompt without doing a thing. Don't know if that's a clue or not. |
