Hi
I have UX21E (asus) on which i have installed linux mint 19 xfce
When it was running MS Windows I could send the computer into hibernation and the battery would last for a few days at least.
Since installing the linux mint I have noted that the power management if very poor. What can i do do enable hibernation in the computer under linux
Thank you

Re: Power management is worse after instaling linux
It's not 100% unusual for power management to be worse in Linux but hard to say without meaningful system details. PLease copy/paste this to the terminal and copy/paste the text output here (no screenshots please):

Re: Power management is worse after instaling linux
This is a link on setting up hibernation: viewtopic.php?t=273202
I'm afraid quite complex... hibernation was deactivated a while ago because of problems relating to restarting system, but can be activated again. However, obviously hibernation doesn't allow you reduce power useage whilst using the computer. You should consider maybe using suspend instead (after period of time), and when not using your computer, simply shutting it down.
Unfortunately windows tends to have better power management than linux. I work in Africa (lots of powercuts) and do 3 things to help with power saving:
1. Install 'TLP' (it is in software manager) this automatically assists reduction in battery useage
2. Reduce brightness of monitor amd adjust power settings (right click on battery icon). This allows you to adjust suspend settings too.
3. Install 'indicator-cpufreq'. Also found in software manager. This allows you to swap between 'performance' and 'powersave' with a small applet that automatically gets added to panel next time you boot in.
To install TLP and indicator-cpufreq at command line instead, you can:

Thank you for the suggestions.
Is there a front end for TLP?

Re: Power management is worse after instaling linux
Just wanted to say thanks for suggesting tlp, I noticed similar battery drain issue on my HP laptop coming from Windows.
I think you just need to use and it should automatically run for subsequent sessions (correct me if I'm wrong).
