Power Management Tool `TLP` 0.8 Released

Ubuntu Laptop

A complete list of TLP features can be found HERE.

Changes in TLP 0.8:

  • General:
  • TLP_DEFAULT_MODE: change default operation mode to AC when no power supply can be detected (concerns some desktop and embedded hardware only)
  • Radio Devices:
  • Resume: restore bluetooth state
  • Radio Device Wizard (tlp-rdw):
  • Support ThinkPad OneLink Dock Basic/Pro for dock/undock events
  • Detect systemd "predictable network interface names" for WWAN
  • ThinkPad Battery:
  • tpacpi-bat: new upstream version 2.2: get ASL path from /sys/class/power_supply/*/device/path; avoids unnecessary "AE_NOT_FOUND" kernel messages
  • tlp-stat:
  • Show "No batteries detected."
  • Explain battery status "Unknown" as "threshold effective"
  • Show battery cell group voltages (verbose mode, tp-smapi only)
  • Show acpi-call suggestion for ThinkPad *40, *50, X1 models
  • USB:
  • tlp-stat:
  • Show warnings for ata errors by default
  • Bugfixes
  • tlp-stat: detect kernel config with PM_RUNTIME=N
  • tlp recalibrate: fix exitcode check
  • USB autosuspend: write power/control if actually changing only
  • Ignore missing files in /proc/sys/fs/xfs

According to the changelog, the "USB_DRIVER_BLACKLIST" feature was removed because it caused issues with AC/BAT switching (the CPU governor didn't change when going from AC to battery or the other way around) and USB hotplugging (required for udevd v221 and higher) - issue HERE.
