<div dir="ltr"><div>Hello fellow Ubuntu users.</div><div><br></div><div>A couple of days ago, I noticed that while my computer was connected to a main power supply, my battery was not charging. I became concerned with this enough to call the manufacturer.</div><div><br></div><div>After some discussion, it appears that this is a feature of some laptop batteries: they are programmed at some point not to charge so their life can be extended - such was the rationale that was put to me by the support representative.</div><div><br></div><div>In the conversation with the representative, I told them that my laptop was running Ubuntu, and they said that, because I was not running Windows 10, they could not perform conclusive diagnostics, and so the subject of installation of Windows 10 was touted as a likely necessary step that would decide whether this feature-of-some-laptop-batteries was or was not the cause of the behaviour I was experiencing.</div><div><br></div><div>Thankfully, the support rendered did not lead me to do this after I observed the battery begin charging once more after I left it unplugged until the battery's capacity drained below 50%. The battery is now fully charged and my laptop is (as it always was) operating without a problem.<br></div><div><br></div><div>While I was trying to understand what was going on, I found the "upower" Ubuntu CLI command. Running upower on this laptop while it was plugged in gave me the following output while I was experiencing the aforementioned feature:</div><div><br></div><div><span style="font-family:monospace">owen@owen-Yoga-Slim-7-Pro-14ACH5:~$ upower -i /org/freedesktop/UPower/devices/battery_BAT0<br> native-path: BAT0<br> vendor: Sunwoda<br> model: L19D4PH3<br> serial: 55478<br> power supply: yes<br> updated: Fri 25 Aug 2023 14:38:24 (59 seconds ago)<br> has history: yes<br> has statistics: yes<br> battery<br> present: yes<br> rechargeable: yes<br> state: pending-charge<br> warning-level: none<br> energy: 52.76 Wh<br> energy-empty: 0 Wh<br> energy-full: 54.86 Wh<br> energy-full-design: 61 Wh<br> energy-rate: 0 W<br> voltage: 17.209 V<br> charge-cycles: 200<br> percentage: 96%<br> capacity: 89.9344%<br> technology: lithium-polymer<br> icon-name: 'battery-full-charging-symbolic'</span><br><br></div><div>The only indication I can see with this output that might indicate the presence of a charging feature is the value of "pending-charge" against the battery state label. So, I am still a little curious as to whether this command gives me
all I need to know about what the battery is doing, and, if not, is
there anything else I can do to dig deeper. Perhaps, should something similar occur again, I can avoid discussion of Windows 10 installation if I can disclose more conclusive information.</div><div><br></div><div>Thanks,</div><div><br></div><div> Owen.<br></div></div>
