• tpacpi-bat: auto detection of all ThinkPad models (v2.1);
• tlp-stat: include newer models in tpacpi-bat suggestions;
• tlp-rdw: support newer docks;
• Handle special case where BAT1 = main battery (Thinkpad Edge/L/S series);
• Fix: sound power save depending on power source ac/bat;
• Fix: don't touch devices in RUNTIME_PM_BLACKLIST or excluded by RUNTIME_PM_ALL=0;
• Fix: do not write sata link power when not configured;
• Fix RESTORE_DEVICE_STATE_ON_STARTUP;
• Restore bay power state upon resume only when on bat power and the setting is active;
• Use nmcli before rfkill to change radio state; re-enable wifi on shutdown when not explicitly configured (Ubuntu 14.04).

Install TLP in Ubuntu / Linux Mint

sudo apt-get remove laptop-mode-tools

sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install tlp tlp-rdw

sudo tlp start

• 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:
• Remove USB_DRIVER_BLACKLIST
• 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

• USB:
• USB_DRIVER_BLACKLIST: exclude devices assigned to the listed drivers from USB autosuspend; default: usbhid;
• USB_BLACKLIST_WWAN: match internal driver list instead of USB vendor ids;
• USB_WHITELIST: include devices into USB autosuspend even if already excluded by the driver or WWAN blacklists;
• radio devices: DEVICES_TO_ENABLE_ON_AC/DISABLE_ON_BAT/DISABLE_ON_BAT_NOT_IN_USE: enable/disable radio devices upon change of power source (excluding connected devices) (feature implemented by Pali Rohár);
• ThinkPad Battery:
• provide proper return codes for all battery functions;
• setcharge allowed on battery power;
• do not activate new thresholds with force_discharge anymore (tp-smapi);
• tpacpi-bat: support for ThinkPad E325 charge thresholds;
• tlp-stat:
• new options: -d|--disk, -e|--pcie, -p|--processor, -s|--system, -u|--usb;
• show driver and connection state for all enabled radio devices;
• show driver name in Runtime PM PCI(e) device list;
• show type and state of docks and device bays;
• show type of init system;
• check if TLP's systemd services are enabled;
• RUNTIME_PM_DRIVER_BLACKLIST: exclude PCI(e) devices assigned to drivers;
• support Dell Latitude docks (feature implemented by Pali Rohár);
• added support for NM 0.9.10;
• set performance versus energy savings policy (performance, normal, powersave - requires kernel modules msr and x86_energy_perf_policy from linux-tools);
• fixed dock/undock event processing for ThinkPad Adv Mini Dock and Ultrabase;
• use a more robust USB device event processing.

Install TLP in Ubuntu / Linux Mint

sudo apt-get purge laptop-mode-tools

sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install tlp

sudo tlp start

• set systemd service type to simple, allows tlp service to start asynchronously in the background;
• remove DISABLE_TPACPIBAT from configuration;
• remove DEVICES_TO_ENABLE_ON_RADIOSW from configuration because it's deprecated: works with Ubuntu 12.04/Kernel 3.2 only;
• enable RUNTIME_PM_ALL by default (controls runtime power management for PCI(e) bus devices);
• do not touch kernel settings if param is empty or commented: DISK_IDLE_SECS_ON, MAX_LOST_WORK_SECS_ON, SCHED_POWERSAVE_ON, NMI_WATCHDOG, SATA_LINKPWR_ON, PCIE_ASPM_ON, RADEON_DPM_STATE_ON, RADEON_POWER_PROFILE_ON, WIFI_PWR_ON, SOUND_POWER_SAVE_ON, RUNTIME_PM_ON;
• tlp-stat:
• consider changed sysfs paths for i915 enable_rc6/fbc as of kernel 3.15;
• consider changed sysfs paths for hwmon coretemp/sensors as of kernel 3.15/3.16;
• report speed of all fans, not just the first one;
• show warning for kernel sata errors (possibly) caused by SATA_LINKPWR_ON_BAT/AC=min/medium power;
• retrieve trace output from systemd journal if present;
• do not disable TLP when laptop-mode-tools is detected, just output a warning about possible conflicts;
• fix: Makefile - remove tlp-nop in uninstall-tlp target;
• fix: tlp-stat - don't suggest tp-smapi on non-ThinkPad hardware with thinkpad_acpi loaded;
• fix: tlp-stat - don't show /proc/acpi/ibm/fan on Lenovo non-ThinkPad models.
