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:

Battery Features

  • Issue #415: ThinkPad X240 discharge BAT1 malfunction when BAT0 is not installed

Disks

  • Fix NVMe detection on Linux 4.15

tlp-stat

  • Issue #430: ignore HID device batteries
