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!

    The CMOS battery has maybe 100mA and lasts 5 years. A laptop battery has at least 400x the capacity, it would not drain in a few days.
