Description

Created attachment 9057 Old style images highlighting the location of "Critical Battery Power Level" vs "Consider the computer on low power at"

Captured Issue:

  • On a 2 year old laptop, battery is working within 100-47% range. Below that level - laptop is dead.
  • In (Xfce4-power-manager) manager, I saw no ability to set critical level above 20%. Which means - dead laptop session every day.
  • Dropped session is damaging battery even more (because previously battery worked safely within 100-40 %, and previously 100-30%. Brand new -> 100-10%).
  • Plugged to electricity laptop should not die. But I saw the popup that battery was discharging. And when reaching it's "new limit" - the session was dead.

Reproduced 3 times. Now - laptop is not starting.

Expected Solution:

  • Software: User can set the XX "%" without limits (with warnings when crossing boundaries like 5-20%).
  • If needed, "Critical Battery Power Level" will update "Consider the computer on low power at" or will provide a "link" to the setting.
  • Hardware: replace battery/laptop.

P.S. I though that when laptop is plugged /connected to the electricity source, even if battery is 1% - the user can work (even with imperfect battery). But when battery is discharging below it's working range limit - it's a damage to the hardware.

  • Xubuntu 18.04.3 LTS with Xfce4-power-manager. With the latest update made max 1-4 days ago. (Using Xubuntu as a daily system for about 1-2 years). Hardware (Laptop):
