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. System: * 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): * Clevo N131WU 13.3" * Intel Core i7-8550U Quad Core (8 threads) @1.8GHz, 4.0GHz Turbo, 8MB cache * 13.3” Full-HD 1920×1080 16:9 IPS LED-Backlit, Mat * 32GB (2x 16GB) Corsair Vengeance LPX DDR4 SODIMM 2400MHz * Samsung 960 PRO (PCI-e, NVMe) 1TB @3.500/2.100MB/s (read/write) * Intel AC-9260 WiFi module 1730Mbps, 802.11AC +Bluetooth 5.0
Changed bug to a blocker. Because for older laptop batteries - it's a blocker (at least it is a critical issue). Because hardware damage is involved. Not only the dropped session.
You can set the critical power action ("On critical battery power:") to "Do Nothing", then the power manager doesn't do anything (and as far as I understand your report, that's what you want).
Or do you expect the power manager to suspend the laptop at 48%?
It seems that Sergiusz wants to set a critical power level at somwhere around 48-50% since his laptop shuts down automatically when it goes below 47%. Maybe a functionality which allows him to trigger an "Ask" on "On critical battery power" setting so that the user can be notified about the levels dropping. Also, I am a new contributor and I am looking for a chance to contribute. If incase it seems to be a problem that needs a fix I'd want to try my hands on and get a taste of contributing to this project.
