Manage your laptop power/battery life in Fedora/Debian/openSuSe

Manage your laptop power/battery life in Fedora 17/18/19/Debian 6/7/openSuSe 12.1

TLP is a power management tool for Linux. It brings you the benefits of advanced power management without the need to understand every technical detail.
TLP does not replace but enhance the existing power management of your Linux installation. TLP applies it's settings upon system start-up and on every change of the power source.
TLP is a pure command line tool with automated background tasks. It does not contain a GUI.

With each release cycle the Linux kernel and the distributions implement new improvements in terms of laptop power management. Therefore even plain standard installations can show quite good results.
Additional possibilities to save battery power are easily found on the web with the search engine of your choice. But selecting the right solutions for your particular hardware and Linux flavor from the myriad of wikis, blogs and forums is much more difficult and often requires advanced Linux knowledge on behalf of the user.

Settings depending on the Power Source:

• Kernel laptop mode and dirty buffer timeouts
• Processor frequency scaling including "turbo boost" / "turbo core"
• Power aware process scheduler for multi-core/hyper-threading
• Hard disk advanced power management 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
• Wifi power saving mode – depending on kernel/driver
• Power off optical drive in drive bay (on battery)

Additional functions:

• I/O scheduler (per disk)
• USB auto-suspend with blacklist
• Audio power saving mode – hda_intel, ac97
• Enable or disable integrated WiFi, blue-tooth or wwan devices upon system start-up and shutdown
• Restore radio device state on system start-up (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 – Think-pads only
• Re-calibrate battery – Think-pads only
