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.
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 Intel CPU max/min P-state to control power dissipation (Intel P-state only)
- Intel CPU energy/performance policies HWP.EPP (Intel P-state only) and EPB
- 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
- 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
- Battery charge thresholds and recalibration - ThinkPads only
TLP packages are available for all major Linux distributions; see Installation.
The default configuration provides optimized power saving out of the box.
