TLP README - 16.12.2018 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. Nevertheless TLP is highly customizable to fulfil your specific requirements. TLP is a pure command line tool with automated background tasks. It does not contain a GUI. Separate settings profiles depending on the power source AC/battery: - Kernel laptop mode and dirty buffer params - Processor frequency scaling including "turbo boost" / "turbo core" - Limit max/min P-state to control power dissipation of the CPU - intel_pstate only - HWP energy performance hints - Power aware process scheduler for multi-core/hyper-threading - Processor performance versus energy savings policy (x86_energy_perf_policy) - Hard disk advanced power magement level (APM) and spin down timeout (per disk) - AHCI link power management (ALPM) with device blacklist - AHCI runtime power management for host controllers and disks *EXPERIMENTAL* - PCIe active state power management (PCIe ASPM) - Runtime power management for PCI(e) bus devices - Intel GPU frequency limits - Radeon graphics power management (KMS and DPM) - Wifi power saving mode - Enable/disable integrated radio devices (excluding connected devices) - Power off optical drive in UltraBay/MediaBay - Audio power saving mode Additional functions: - I/O scheduler (per disk) - USB autosuspend with device blacklist/whitelist (input devices excluded automatically) - 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 and bluetooth 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.
