Description : Power management tool for Linux. It brings you the benefits of advanced power management without the need to understand every technical detail.
TLP implements advanced power management for Linux. TLP is a pure command line tool with
automated background tasks. It does not contain a GUI.
Settings depending on the power source ac/bat:
- Kernel laptop mode and dirty buffer params
- 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)
- PCIe active state power management (PCIe ASPM) - Kernel 2.6.35 and above
- Runtime power management for PCI(e) bus devices - Kernel 2.6.35 and above
- Radeon graphics KMS power management - Kernel 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 autosuspend with blacklist (input devices excluded automatically)
- Audio power saving mode - hda_intel, ac97
- Enable or disable integrated radio 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
- Integrated 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
All TLP settings are stored in /etc/default/tlp. The default configuration
provides optimized power saving out of the box.
