TLP - Linux Advanced Power Management

TLP saves laptop battery power on 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.

Power profiles

Depending on the power source (AC or battery) the following settings are applied:

• 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)
• Disk drive advanced power management level (APM) and spin down timeout
• 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 PCIe 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 features

• 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

Installation

TLP packages are available for all major Linux distributions; see Installation.

Configuration

The default configuration provides optimized power saving out of the box.

Settings are stored in /etc/default/tlp; see Configuration for details.
