Hello! My girlfriend’s HP laptop running kubuntu 24.04 has this problem: when it’s turned off (either from the GUI or poweroff) it discharges overnight, from 100% to 0% in a few days.
I searched the web to look for fixes:
- wake on lan is disabled in the BIOS
- USB ports have no settings in the bios, but there’s nothing connected to them anyway
- the system is actually powered off, not sleeping (at least if
poweroffactually works) - everything, firmware included, is up to date
She doesn’t remember having this problem from the beginning, but cannot tell when this started occurring
Did any of you ever encounter this problem? I don’t know what else to do, and it’s quite annoying.
Thank you for your time!
I would check the journalctl logs to ensure it is fully turning off. If here is still battery drain and you are sure the laptop is off, then its a hardware issue rather than software.
how do I check this? This is probably the source of the issue (see this comment), but I have no idea on what to do to understand the actual cause
thanks for your time and help!
This is a good place to start to understand what you are doing: https://www.howtogeek.com/499623/how-to-use-journalctl-to-read-linux-system-logs/
But basically you shut the computer off, then on then do
journalctl -S -3mWill show the last 3 mins of logs which you can go through and try to read the logs up until the moment it actually turns off to see what is happening.
