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 poweroff actually 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!

    let’s hope it’s a software issue, in general it’s much cheaper to fix software than hardware 🙂

    you can also try using the “sudo halt --poweroff” command.

    if it ks software related. that command will force an instant shutdown ignoring all normal shutdown run levels (use with caution if you have open files that need to be saved in advance).

    if that command succeeds as well after the battery test, you can be sure the problem lies within the shutdown run level scripts, which should help you narrow it down even more.

      okay, I think we have some news: if I kill the pc by holding the power button, after a night the battery loses 0%! so I guess the problem is that it’s not shutting down properly. I tried to sudo halt --poweroff and it drained the battery as usual. I then tried sudo halt -f and something strange happened: the screen immediately turned off, but the red LED on the volume key indicating that the volume is muted stayed on, so the pc wasn’t completely off. what could be the problem? and why does this happen only when I force the halt? could it be a kernel issue?

      thanks for the help and for your time!!!

        Hi, a bit busy today so I can investigate some more later, but the problem you are describing is in many cases related to the kernel version and has been resolved by up or downgrading the kernel version.

        it might be worth looking into, at least it’s a simple task, while I get some more time to investigate or offer more for you to look into.

        great that it worked so far, at least now you know where the problem is :)

          I’ll try other kernels then, but I don’t know how to check if the system is actually powered off or not without waiting 8 hours and checking the battery drain XD perhaps the halt could be the key

          thanks!! I’ll update the thread if I’ll discover something new
