Battery Life Issue

Support & Help Requests
1

Hello,

I recently did a reinstall of Ubuntu MATE 15.10 about a couple weeks ago or so, and I’ve noticed a strange issue with my battery life. After using my computer for about 30-45 minutes, I get a pop up from the battery applet in the tray saying my battery is critically low, and in about 10 seconds my system will hibernate itself (from there I then need to hold down the power button to force it off, and plug in my charger). I know for a fact my battery isn’t this bad, and I have not had this issue with previous installs of Ubuntu including 14.04 and 14.10, nor have I had this problem with previous installs of Ubuntu MATE 15.10.

I am running Ubuntu MATE 15.10 on a stock Lenovo Y40-80 with the latest updates as of writing this message. The kernel is 4.2.0-35-generic. I have AMD proprietary drivers from fglrx-updates (which I have previously used and has been fine). If there is any other information I can provide please let me know.

I think that battery is just dying .
About the notification and hibernation . You can fix this by two ways . Completely disable hibernation on low battery via Control Center/Power Managment . or you could lower the battery percentage it considers the battery low .

The second solution can be done via dconf-editor (if you don’t have it you can install it via : sudo apt-get install dconf-editor)

  1. Open dconf-editor
    2.Go to /org/mate/power-manager
    3.Uncheck use-time-for-policy
    4.Set percentage-low,percantage-action and percentage-critical to wath percent you like like (2% is good enough for percentage-action to delay hibernating maximum amount of time )
