: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 fulfill your specific requirements.
Settings depending on the power source ac/bat:
+
* Kernel laptop mode and dirty buffer params
+
* CPU scaling governor and mix/max frequencies
+
* 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).

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 fulfill your specific requirements.

Installation

Install tlp from the official repositories - pay attention to its optional dependencies that may help provide additional power saving.

To complete TLP's install, you must enable the systemd services tlp.service and tlp-sleep.service. You should also disable the systemd service systemd-rfkill.service to avoid conflicts and assure proper operation of TLP's radio device switching options.

Note: tlp.service starts NetworkManager.service if it is available: FS#43733. If you use a different network manager, edit tlp.servicein order to remove the service (line Wants=) or mask it.

ThinkPads only

For advanced battery functions, i.e. charge thresholds and recalibration, install the following package(s):

  • tp_smapi – needed for X220, T420 and older models
  • acpi_call – needed for X220, T420 and newer models

Start

After installation TLP will be automatically activated upon system start. To start it immediately without reboot or to apply changed settings, use:

# tlp start

Configuration

The configuration file is located at /etc/default/tlp and provides a "largely" optimized power saving by default. For a full explanation of options see: TLP configuration.

btrfs

To avoid filesystem corruption on btrfs formatted partitions, set:

SATA_LINKPWR_ON_BAT=max_performance

See also these links for discussion on this topic: Github bug report, Reddit follow-up discussion.

Radio Device Wizard

The Radio Device Wizard allows a more sophisticated management of radio devices depending on network connect/disconnect events. It requires NetworkManager, tlp-rdw and enabling NetworkManager-dispatcher.service.

See TLP configuration for details.

Command line

TLP provides several command line tools. See TLP commands.
