Good day to smart people:

I am back into Linux and i just installed Fedora 23, 64bit through Net install, and it went much better than "opensuse." It accurately installed with very little effect. After installing Fedora 23, 64bit on my laptop i ran into just a minor issue to power management. When battery is fully charged and I ran Fedora I get around 2.5 hours of work load, this is just doing 100% stuff from the web(firefox), like opening my pdf resume and filling out job applications and checking email from outlook and gmail. The CPU fan is always running but not full speed; So nothing i have done could have use that much horse power, right? when my laptop is fully charged and i ran "windows 7 64bit prof" i get around 4 hours of battery usage. i have listed my spec of my laptop below; would someone please assist me on pro longing the battery usage. I would love to go 100% on linux but don't want to carry charger to places if i don't have to.

Laptop Spec: Laptop Battery 9 Cells in good health conditions according to the BIOS E6420 with nVidiaChips 8GB DDR3 256 SSD BIOS A21

I am comfortable with terminal command lines

With system monitor (both GNOME and KDE) or the command line utility htop you can look at CPU times (a column hidden by default). This is a sum of all time a process spend on your machine. You may want to look at the "top ten".

To track down what is eating your power you might want to try powertop (cli tool). But please beware, those power management settings it tries to do on the last page are pretty dangerous. There is a similiar GUI tool, gnome-power-manager.

Your graphics card might be missing a driver. Can you check that? I don't know whether the proprietary nvidia driver or the open source one is better in terms of power management. You might want to try both.

You might want to have a look at these Arch wiki entries (they should apply to fedora too, mostly): https://wiki.archlinux.org/index.php/... https://wiki.archlinux.org/index.php/... Proprietary drivers are available at http://rpmfusion.org/ .
