From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

HP Laptop drains battery while turned off (lemmy.kde.social)

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!

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 -3m

Will 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.
