Hello, I have HP laptop with Intel Motherboard and ATI graphics Card. I have successfully installed ATI Proprietary Drivers in Fedora19-GNOME. Its working nicely, still my battery hardly works for 1hour and 45 minutes. Previously with Windows7, it use to work for 3 hours.

I have also kept brightness to lower level.

Please help what needs to be done to increase the battery life.

I own a HP laptop DV6 and run Fedora 19 on it. Without any optimization, the laptop consumes in average 35W. To decrease the default power consumption, I disabled the ATI graphics card. Well, I do not use the ATI Proprietary Drivers to disable the ATI card. Instead of this I use the switcheroo feature. With enabled internal Intel graphics card and Tuned[1], the power consumption drops below 14W (average).

Whats your measured power consumption?

To optimize battery life try to reduce the number of services running to what you really need.

E.g. the default full Gnome3 installation includes bluetooth setup. If you do not connect bluetooth devices you can disable this. Even if you use bluetooth devices sometimes it will help to disable it when you don't use them.

Same applies to other services.

Powertop can also be used to track down which applications and services are consuming the most power and will even provide some tips to reduce their power usage.

Have a look at the Power Management Guide in the fedora documentation.

There's a few tools that can help you save some battery life, i will start with the basics.

1 - Install Juppiter applet from here.

2 - Install TLP, do read their manual page here.

TLP brings you the benefits of advanced power management for Linux without the need to understand every technical detail. TLP comes with a default configuration already optimized for battery life, so you may just install and forget it.

Open a console and type as root or with sudo:

 yum localinstall --nogpgcheck http://repo.linrunner.de/fedora/tlp/repos/releases/tlp-release-1.0-0.noarch.rpm

yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm 

yum install tlp tlp-rdw

Thinkpads require aditional packages:

 yum install akmod-tp_smapi akmod-acpi_call

To manual start (after reboot it will automatically start):

sudo tlp start

To check the status:

sudo tlp-stat

Finally all you'll ever need to know about powersaving features right here

It looks like Jupiter has been retired and not maintained for nearly a year before this posting. Perhaps there's another way, with packages that are currently available in Fedora?
