There are quite a few tools exists to power saving and battery life extension in Laptops. We already have looked at two tools namely Laptop Mode Tools and Powertop that improves the Linux Laptop battery performance. Today we will discuss yet another Laptop power management utility named TLP. TLP is a feature-rich commandline tool to optimize Laptop battery life in Linux.

What is TLP?
TLP is an advanced power management tool for Linux. Its goal is to improve battery life on laptops running Linux without the need for complex configurations.
TLP requires zero configuration. TLP comes with a default configuration that's already optimized for battery life. It implements Powertop's recommendations out of the box. So users can simply install it and forget about it.
Some of the things TLP handles include:
- Power source-dependent configuration (whether you're running on battery or AC power)
- Processor frequency scaling including "turbo boost" / "turbo core"
- Power-saving settings for your hard disk or SSD
- Runtime power management for PCI(e) bus devices
- Wi-Fi power saving mode
- And more.
TLP will apply these settings automatically depending on your power source. It's a great tool for Linux laptop users who want to maximize their battery life with minimal hassle.
TLP takes care of everything. Even though TLP's default settings are just enough to provide optimal battery life, it is highly customizable to fulfill a specific requirement.
Install TLP in Linux
TLP is packaged for many Linux distributions including Arch Linux, Debian, Fedora, Gentoo, openSUSE and Ubuntu.
To install TLP in Arch Linux and its variants, run:
$ sudo pacman -S tlp tlp-rdw
If you're using Thinkpad, you need to install any one of the following packages. If you don't know exactly which package to install, run tlp-stat -b command as sudo or root user. It will guide you which package to install.
- acpi_call-lts (Community) – This is an optional external kernel module for the LTS kernel. It provides battery recalibration for ThinkPad models from the year 2011 onwards, such as the T420/X220 and newer models.
- tp_smapi (Community) – This is an optional external kernel module. It provides battery charge thresholds and recalibration for ThinkPads made before the year 2011. It also provides specific tlp-stat -b output for models made until the year 2011.
- tp_smapi-lts (Community) – This is optional. Use it instead of tp_smapi when the LTS kernel is installed.
Install the appropriate package using your preferred package manager or with the following command:
$ sudo pacman -S acpi_call
Replace acpi_call with acpi_call-lts, tp_smapi or tp_smapi-lts where suitable.
On Debian:
$ sudo apt install tlp tlp-rdw
If you are using any Thinkpad model Laptops, you may need to install any one of the following packages. The output of tlp-stat -b will guide you which package to install.
- acpi-call-dkms (main) – This is an optional external kernel module that provides battery recalibration for ThinkPad models from the year 2011 onwards, such as the T420/X220 and newer.
- tp-smapi-dkms (main) – This is an optional external kernel module. It provides battery charge thresholds and recalibration for ThinkPads made before the year 2011. It also provides specific tlp-stat -b output for models made until the year 2011.
Install the appropriate package using your preferred package manager or with the following command:
$ sudo apt install acpi-call-dkms
Replace 'acpi-call-dkms' with 'tp-smapi-dkms' as needed.
On Fedora:
$ sudo dnf install tlp tlp-rdw
If you use any Thinkpad model Laptops, install any one of the following packages. The dependencies of following packages are not available in the default repositories. So, first enable RPM Fusion repository in Fedora and then install the appropriate packages. If you don't know which package to install, run tlp-stat -b command as sudo or root user.
- kernel-devel (Fedora repo) – This is required to build the kernel module from the akmod package.
- akmod-tp_smapi (ThinkPad Extras repo) – This is an optional external kernel module source that provides battery charge thresholds and recalibration.
On openSUSE:
$ sudo zypper install tlp tlp-rdw
For Thinkpads, install the appropriate packages.
- acpi_call – This is an optional external kernel module that provides battery recalibration for ThinkPad models from the year 2011 onwards, such as the T420/X220 and newer.
- tp_smapi – This is an optional external kernel module. It provides battery charge thresholds and recalibration for ThinkPads made before the year 2011. It also provides specific tlp-stat -b output for models made until the year 2011.
On Ubuntu:
To install TLP in Ubuntu and its derivatives, add the TLP official PPA:
$ sudo add-apt-repository ppa:linrunner/tlp
And install TLP using command:
$ sudo apt install tlp tlp-rdw
For Thinkpad Laptops, install the appropriate packages:
- acpi-call-dkms (PPA or universe) – This is an optional external kernel module that provides battery recalibration for ThinkPad models from the year 2011 onwards, such as the T420/X220 and newer.
- tp-smapi-dkms (universe) – This is an optional external kernel module. It provides battery charge thresholds and recalibration for ThinkPads made before the year 2011. It also provides specific tlp-stat -b output for models made until the year 2011.
You can install the appropriate package either using your preferred package manager or with the following command:
$ sudo apt install acpi-call-dkms
If necessary, replace 'acpi-call-dkms' with 'tp-smapi-dkms'.
Again if you don't know which package to install, run tlp-stat -b command as sudo or root.
Enable and start TLP service
After installing TLP on your Linux machine, make sure it is enabled on startup and start the service using commands:
$ sudo systemctl enable tlp.service
$ sudo systemctl start tlp.service
You should also mask the following services to avoid conflicts and assure proper operation of TLP's Radio Device Switching options:
$ sudo systemctl mask systemd-rfkill.service
$ sudo systemctl mask systemd-rfkill.socket
Optimize Laptop Battery Life with TLP in Linux
As I already mentioned, TLP requires NO configuration. It works out of the box! The default settings are well optimized for better Laptop battery life. You can view these default settings in the TLP default configuration file, which is located at /etc/tlp.conf.
To view the current TLP configurion, system information, active power saving settings and battery data, run:
$ sudo tlp-stat

Disable USB auto suspend
When TLP is started with default configuration, some USB devices will be automatically suspended to save power when your Laptop is running on battery.
To disable USB autosuspend, edit /etc/tlp.conf file:
$ sudo nano /etc/tlp.conf
Find the following line and set its value as 0.
USB_AUTOSUSPEND=0
You can also exclude specific devices from USB autosuspend (separate with spaces). First, use lsusb command to get the ids. Then, mention the device ids with space-separated like below
USB_BLACKLIST="8078:0014 065d:8023"
Save and close the file by pressing CTRL+O followed by CTRL+X.
Force battery (BAT) configuration
When no power supply is detected, the setting for AC will be used on devices like desktops and embedded hardware. If you want to force the battery (BAT) settings when using TLP on these devices to enable more power saving, edit /etc/tlp.conf file:
$ sudo nano /etc/tlp.conf
Find the following lines and set their values as shown here:
# Operation mode when no power supply can be detected: AC, BAT. TLP_DEFAULT_MODE=BAT # Operation mode select: 0=depend on power source, 1=always use TLP_DEFAULT_MODE TLP_PERSISTENT_DEFAULT=1
For more details, check the TLP website and its GitHub page given at the end.
