Tweaks To Extend The Battery Life Of Intel Linux Notebooks

This thread should collect some tips & tricks about powersaving in Linux. If you have a useful information on how to save Watts, extend battery life, reduce power consumption, fan noise, heat from CPU/GPUs etc. please share.A very good and informative website on the topic is http://www.lesswatts.org/Thanks in advance!

I've just installed Xubuntu on my Samsung 530U (SSD version) and everything works find, but the battery life is dramatically lower comparing to Win7.

I upgraded my T420 thinkpad to kernel 3.6.9-1-ARCH and today realized that the battery life is only around 2 hours (usually I get 6 with a 6-cell battery).  Is anyone else having problems with unusually high power consumption on this kernel?My temporary solution was to downgraded the kernel to 3.6.8-1-ARCH.  I'll keep "IgnorePkg = linux linux-headers" until the next kernel

Battery life might be the biggest concern of any Android power user. Custom kernels, scripts, and applications are some of the many tools users have to squeak out as much battery life as possible out of their devices.

Hi

I 've been wondering for a long time wheather there is a way how to show the current power consumption when computer are pluged into AC

When on battery, gnome-power-statistics shows how much the system consumes power in Watt but when on adapter and the battery is charged it don't show it. How can I find out my system cosumption in this case?

Powertop, a tool for detecting power wasters under Linux, is about to make a generational jump: version 2.0 provides improved diagnostic options and a redesigned user interface. It also offers a simple, manual way of enabling numerous power-saving features that can noticeably extend the battery life of notebooks. read more

I was a bit disappointed with the battery life of crunchbang out of the gate. I installed laptop-mode-tools but that did not do much. So I hacked together a little script that will enable some power saving tweaks when on battery power, and default to best performance while on AC. It should work on most setups, but YMMV.

My battery backup hardly lasts for 45mins. I searched for a similar problem but din't find any solution applicable to me.

I use Nvidia GeForce 525M graphics card and use nouveau. My laptop gets heated up to about 85 deg (according to jupiter).
