It is well known that the laptop/netbook is on battery is much less when working in one of the Linux systems than Windows installed on the same machine.
There are various tricks that you can apply to your laptop/netbook to save battery, but many of them depend on the hardware, distribution, and some are outdated or too difficult to install for normal users, etc.

- Processor frequency scaling including "turbo boost" / "turbo core"
- Power aware process scheduler for multi-core/hyper-threading
- Hard disk advanced power magement level and spin down timeout (per disk)
- SATA aggressive link power management (ALPM)
- PCI Express active state power management (PCIe ASPM) – Linux 2.6.35 and above
- Runtime power management for PCI(e) bus devices – Linux 2.6.35 and above
- Radeon KMS power management – Linux 2.6.35 and above, not fglrx
- Radeon dynamic power management – Kernel 3.11 and above, not fglrx
- Wifi power saving mode – depending on kernel/driver
- Power off optical drive in drive bay (on battery)
- Audio power saving mode – hda_intel, ac97
- I/O scheduler (per disk)
- USB autosuspend with blacklist
- Enable or disable integrated wifi, bluetooth or wwan devices upon system startup and shutdown
- Restore radio device state on system startup (from previous shutdown).
- Radio device wizard: switch radios upon network connect/disconnect and dock/undock
- Disable Wake On LAN
- WWAN state is restored after suspend/hibernate
- Untervolting of Intel processors – requires kernel with PHC-Patch
- Battery charge thresholds – ThinkPads only
- Recalibrate battery – ThinkPads only
Installation latest version into Linux Mint 13/14/15/16/17/17.1/17.2:
Before installing TLP, there are several conditions which it is desirable to perform:
First. If you added some power saving settings/scripts, etc., delete them or TLP may not work properly;
Second. Remove laptop-mode-tools package
sudo apt-get remove laptop-mode-tools
Now open a terminal, copy and run the following commands:
sudo add-apt-repository ppa:linrunner/tlp sudo apt-get update sudo apt-get install tlp tlp-rdw
TLP does not have a GUI, so after installing the energy efficiency of your laptop/netbook will start after the next and all subsequent logons. But not to reload it now, run the following command:
sudo tlp start
And also there are some packages with additional features that can be installed from the software manager or run the following command:
sudo apt-get install smartmontools ethtool
And some additional packages only for Lenovo ThinkPad laptops:
sudo apt-get install tp-smapi-dkms acpi-call-tools
