TLP 0.8 was released recently, bringing various ThinkPad improvements, systemd "predictable network interface names" support along with other changes and bug fixes.

For those not familiar with TLP, this is an advanced power management tool that applies various settings and tweaks to help your laptop save battery power. The app tries to do everything automatically, depending on your Linux distribution and hardware (it runs in the background and doesn't come with a GUI) however, you can manually change its settings by editing the TLP configuration file: /etc/default/tlp

The latest Laptop Mode Tools 1.65, released yesterday, includes important changes and bug fixes such as support for Intel PState driver and a more robust Runtime Power Management Framework that deprecates the usb-autosuspend module. That means that there should be less issues with USB devices such as mice / keyboards not working properly with LMT (if such issues still occur, you'll need to blacklist the device id or disable the runtime-pm and usb-autosuspend modules using the Laptop Mode Tools GUI).

Laptop Mode Tools is a package that allows you to extend the battery life of your laptop by enabling the Laptop Mode Linux kernel feature along with other power-related tweaks.

This was a command line only tool until version 1.64, which introduces a GUI that lets you toggle individual power saving modules. The new GUI configuration tool isn't exactly pretty as you can see in the screenshot below, but it's definitely an useful addition because it no longer requires users to work with various configuration files.

There are various tweaks that you can apply to your laptop to save battery power, but many of them depend on the hardware, Linux distribution, some are outdated or too hard to apply for regular users and so on. TLP is an advanced power management command line tool for Linux that tries to apply these settings / tweaks for you automatically, depending on your Linux distribution and hardware.

Basically, using the hybrid suspend method from this article, the system initially enters suspend which is quick to resume and after the time you set, the system hibernates so it no longer uses any battery power. This is useful if for example you close the lid when you move from one room to another (between meetings, classrooms, etc.) and you need the system to resume quickly, but you also want to preserve battery power if you don't use it.
