laptop config on mandrake 10.0 official

[f3ua]

Hi at all!

I'm writing you for informations about setting up mdk 10.0 on my laptop to improve my battery's life.

can you help me? thanks!

So are you wanting to install Mandrake 10 on your laptop as a computer operating system? Or is it you are under the impression that Mandrake 10 will improve your battery's life? If Mandrake 10 can do that, it's something I'm not aware of.

Can you give us a little more information about what you want to do? That way, we can better understand, and hopefully give you some help.

MDK 10.1 claims to be the best laptop distro out there and from what i've seen, it truely is. If you don't mind Community Edition, then you can use it today. Otherwise, official should be out soon.

Thank you for your replies, i'm giving you more information about what I have to do.

I've already installed that distro on my laptop, ant it work quite good (no 3d acceleration with radeon 9700 mobility), but it doesn't matter.

I noticed that battery's life in windows is longer than in linux, because windows slow down CPU & VPU speed, when using the battery.
In linux (I suppose) this not happen, and, for example, cpu fan is always on.

I'm asking you if there are some modules to install, for controlling the energy use of the laptop (for example, best performance, balanced, longer battery life options)

Thanks again, and sorry me for my english but i'm italian and this is not my first language.

Bye!

ATI provides drivers for that card, I've heard they worked great.

As for power management... become root, then edit /etc/lilo.conf and change acpi=ht to acpi=force, then run the lilo -v command. You may additionally have to install both acpi and acpid.

ACPI offers much finer control of pm then APM, inclusing temp control and cpu throttling.

jeremy1701, my wife has a Toshiba laptop running Mepis RC4, and it seems to have battery problems, (longevity issues) as well. Is what you're recommending to f3ua a general solution for Linux laptops are just particular to Mandrake 10? If so, is there a way to do it even if you're not using lilo?

[jeremy1701]

it's general. You can add this option to both lilo.conf and grub ( i think it's /boot/lst.conf ??). The acpi and acpid applies to all. Another option you can try is acpi=on, rather then force. ht means "not in X".

ok, I've modifyed lilo.conf and rebooted the system. From dmesg I get this:

ecc.... ecc....

It's all right? now how can I control cpu speed? where can I find informations or how to for using ACPI?

Thanks a lot!!!!

[jeremy1701]

there's a program called klaptop where you can adjust the settings of ACPI.

Thanks a lot. I'm trying it, and i'll post the results.
