Available packages are listed on the download page.

TLP 1.3.1

Bugfixes:

Processor

• Issue #460: default CPU_ENERGY_PERF_POLICY_ON_BAT=power too aggressive

TLP 1.3.0

New Features:

New configuration scheme

• /etc/default/tlp is replaced by /etc/tlp.conf
• Settings are read in the following order:
  1. Intrinsic defaults
  2. /etc/tlp.d/*.conf - Drop-in customization snippets
  3. /etc/tlp.conf - User configuration
  In case of identical parameters, the last occurence has precedence
• Parse config files instead of sourcing --> no more shell expansion

Battery Features, tlp-stat -b

• Charge thresholds: better checks for command line and configuration; clearer error messages
• tlp discharge: error message "check your hardware" when battery wasn't completely discharged (Issue #438)
• Distinguish between "no kernel support" for natacpi (< 4.17) and "laptop not supported" (>= 4.17)
• Supplement battery status "Unknown" with "threshold may prevent charging" when thresholds are available only

General

• systemd: replace tlp-sleep.service with /lib/systemd/system-sleep/tlp

Operation Mode AC/BAT

• TLP_PS_IGNORE: power supply class to ignore when determining operation mode; workaround for laptops reporting incorrect AC or battery status (Issue #446)

PCI(e) devices

• PCIE_ASPM_ON_AC/BAT: add method 'powersupersave' (Issue #425)

Processor

• CPU_ENERGY_PERF_POLICY_ON_AC/BAT: backward compatible merge of settings for Intel energy vs. performance policies EPB (ENERGY_PERF_POLICY_ON_AC/BAT) and HWP.EPP (CPU_HWP_ON_AC/BAT); when HWP.EPP is available, EPB is not set; validate parameters; eliminate external tool x86_energy_perf_policy for kernel >= 5.2

tlp-stat

• Configuration: show file where the parameter comes from
• System Info:
  • Show SELinux status
  • Show RDW as 'disabled' when TLP is disabled as a whole
  • Indicate persistent mode
• Intel CPU: don't show EPB values when HWP.EPP is active (see above)
• PCIe ASPM: show available policies
• Undervolting: remove "PHC kernel not available" message

Bugfixes:
