Slackware 14 (64-Bit Install) on laptop = Terrible battery life?

Try using this package from SlackBuilds and see if it helps with maintaining your battery.

Also, you will want to use the proprietary drivers for any video hardware you have as they will contain more power saving tools and management options.

It is a conflict for stock pm-utils.

How do you come to that conclusion? Works fine here.

Hi,

I agree with TobiSGD, battery life will also depend on your graphics chipset. Noticed major differences when using the Intel graphics and then switch to Nvidia via BumbleBee-Optirun switching. While using the Nvidia then battery life is cut in half.

To be clear, you mean that using nouveau gives worse battery life than nvidia, for example? Or the other way around? Or something else completely?

As for me, my laptop gets a pretty solid hour and a half no matter what the system (Windows or Linux), although I have never tested laptop-mode-tools. I'll give it a spin to see how it works!

Thanks.

Neither the nouveau nor the radeon drivers are up to par with the proprietary drivers when it comes to power-management.

You are right. Laptop mode tools works fine, though it's redundant when slackware already comes with pm-utils.

I have not dig deep. But if you google for "laptop-mode-tool pm-utils conflict", you could see some report of this conflict.

I did: a good hit seems:https://wiki.archlinux.org/index.php/Laptop_Mode_Tools

It shows how to address possible conflicts (add "#Troubleshooting" to above address or scroll to bottom of page), but pm-utils and laptop-mode-tools do not appear mutually exclusive if you inactivate the overlap in their actions.
