TLP is a free open source, feature-rich and command line tool for advanced power management, which helps to optimize battery life in laptops powered by Linux. It runs on every laptop brand, and ships in with a default configuration already tunned to effectively and reliably maintain battery life, so you can simply install and use it.
It performs power saving by allowing you to configure how devices such as CPU, disk, USBs, PCIs, radio devices should utilize power when your laptop is running on battery.
- It is highly configurable through various power saving parameters.
- It uses automated background tasks.
- Uses kernel laptop mode and dirty buffer timeouts.
- Supports processor frequency scaling including “turbo boost” and “turbo core”.
- Has a power aware process scheduler for multi-core/hyper-threading.
- Provides for runtime power management for PCI(e) bus devices.
- PCI Express active state power management (PCIe ASPM).
- Supports radeon graphics power management (KMS and DPM).
- Has a I/O scheduler (per disk).
- Offers USB autosuspend with blacklist.
- Supports Wifi power saving mode.
- Also offers Audio power saving mode.
- Offers hard disk advanced power management level and spin down timeout (per disk).
- Also supports SATA aggressive link power management (ALPM) and so much more.
How to Install TLP Battery Management Tool in Linux
TLP package can be easily installed on Ubuntu as well as corresponding Linux Mint using TLP-PPA repository as shown.
$ sudo add-apt-repository ppa:linrunner/tlp $ sudo apt update $ sudo apt install tlp tlp-rdw
On Debian 10.0 “Buster” and 9.0 “Stretch” add the following line to your /etc/apt/sources.list file.
deb http://ftp.debian.org/debian buster-backports main deb http://ftp.debian.org/debian stretch-backports-sloppy main
and then update the system package cache and install it.
$ sudo apt update $ sudo apt install tlp tlp-rdw
On Fedora, Arch Linux and OpenSuse, execute the following command as per your distribution.
# dnf install tlp tlp-rdw [On Fedora] # pacman -S tlp tlp-rdw [On Arch Linux] # zypper install tlp tlp-rdw [On OpenSUSE]
How to Use TLP to Optimize Battery Life in Linux
Once you have installed TLP, its configuration file is /etc/default/tlp and you will have the following commands to use:
- tlp – apply laptop power saving settings
- tlp-stat – displays all power saving settings
- tlp-pcilist – displays PCI(e) device data
- tlp-usblist – for viewing USB devices data
It should start automatically as a service, you can check if it is running under SystemD using systemctl command.
$ sudo systemctl status tlp
After the service starts running, you have to restart the system to actually start using it. But you can prevent this by manually applying the current laptop power saving settings with root privileges using the sudo command, like so.
$ sudo tlp start
Afterwards, confirm that it is running using the following command, which actually shows system information and TLP status.
$ sudo tlp-stat -s
Important: As we mentioned before, it uses automated background tasks but you will not see any TLP background process or daemon in ps command output.
To view current TLP configuration, run the following command with
$ sudo tlp-stat -c
To display all power settings run the following command.
$ sudo tlp-stat
To display Linux battery information, run the following command with
$ sudo tlp-stat -b
To display Temperatures and Fan Speed of system, run the following command with
$ sudo tlp-stat -t
To display Processor Data, run the following command with
$ sudo tlp-stat -p
To display any Warnings, run the following command with
$ sudo tlp-stat -w
Note: If your are using ThinkPad, there are certain specific packages you need to install for your distribution, that you can check from the TLP homepage. You will also find more information and a number of other usage commands there.

The battery is not charging, and the laptop turns off when the charger is disconnected. Tried removing, putting it back, etc. What can be the reason? “current now” here shows “0”.
So I just have to install it and reboot to get it working right?
I am having an Acer Aspire 315-51z
No need to reboot, just start the tlp service using the following command.
All these tools does is cause a flurry of SELinux messages. I very quickly got tired of SENotify pinging me with messages every 3-4 minutes, so I removed TLP.
Does anybody knows how to handle tlp with audio in battery mode.
When the laptop is connected to the power the audio is ok, but after a while in battery mode the laptop remains without audio. When it gets again the 100% of battery connected to the power the laptop recovers the audio.
I have selected regarding the audio settings:
With these I try to remove the control to TLP for audio purposes, but even with that configuration on battery mode I have no audio.
Take a look at the TLP settings for audio: https://linrunner.de/en/tlp/docs/tlp-configuration.html#audio
I am using Ubuntu 18.04. I am facing a LAN connection problem. The problem is when I start my laptop it will connect to the LAN but once I disconnect it it won’t reconnect. Then I will have to put the laptop in sleep mode and then it would reconnect.
Every time I reinstalled Ubuntu and the problem didn’t showed up for the first 3-4 days and then again the same problem happens. But this time I think I have figured out the reason behind this. there was no issue till today when I installed tlp and started it.
Only after tlp it showed the same problem again. I googled and got to know that tlp activation changes some settings in order to save battery. Is it possible that tlp is the culprit. If so is there any way I can disable a particular setting so that tlp keeps working and I get rid of the problem. And yes I have my laptop dual booted with windows 10 and there is no such issue in windows 10. So certainly it is specific to Ubuntu. I think I have to change some settings. Can someone please help
The TLP module appears to be the cause of problems with Intel network drivers. You could tell me how to stop the service by restoring the options of Default???
TLP Start | true | bat | false | ac | usb | bayoff | discharge | setcharge | fullcharge | recalibrate | stat | diskid
Seems to keep settings also removed the tool
Several users on Fedora and not only report problems to Intel network card drivers and the cause is TLP
I have read through the thread but didn’t see any one directly mention TLP module as the cause of problems with Intel network drivers, although some answers have stressed about disabling Active-State Power Management but not connection with TLP.
You can completely remove it, including config files with this command:
$sudo apt-get purge tlp tlp-rdw
Once you have removed it, try to check if the cause of problems with Intel network drivers was actually TLP, and give us some feedback.
Look I ran in doubt a clean installation of Fedora 28 without TLP… No problem…..
The problem arise the next reboot after the installation of TLP…… Is that and since it is no longer installed I see no more error reported!!!!
Okay, it could have caused the problems with Intel network drivers, which your were facing and other Fedora users. And by the way, the correct command for removing it on Fedora is:
#dnf remove tlp tlp-rdw
Thanks for the feedback, we will update this article to include this issue. You can also raise this issue to the developer via: http://linrunner.de/en/tlp/docs/tlp-linux-advanced-power-management.html
Also removed the settings given to the kernel remain, otherwise I think until there I would have arrived….
The developer is already a week knows of the problem from me reported on GIT!!!!!
Anyway we Blog I follow you very much!!!!
I don’t know how to stop certain service on Fedora, but on Ubuntu you would run ‘sudo systemctl stop tlp‘.
I used tlp on my ubuntu 16.04 partitioned with LVM, it causes me a lot of system crashes, which force me to hard reset laptop on each crash.
Does any one have idea about this issue ?
Try contacting the developers by posting the issue here: https://github.com/linrunner/TLP
Under lubuntu 16.04 lts, can xfce power manager and tlp coexist? if not how to disable xfce power manager?
Try to go to Session and Startup->Application Autostart, then locate Power Manager in the list and uncheck it. If you fail to find it, you can check the documentation for xfce.
I already tried through “Default applications for LXSession->LXSession configuration->Autostart, uncheked power manager” as Admin user and normal user. It is not making any difference. Xfce Power manager always present.
Try to contact the developers of Xfce, possibly on via the project homepage: https://xfce.org/
