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!

Laptops now use the internal main battery as a replacement of the cmos rs2032 battery (in a lot of em at least).

Not that such a low draw cause this level of drain. Maybe the battery is going out as well.

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.

I checked and yes, there's no cmos battery in it. Do you think this may have something to do with it?

Hard to say. But it's something to consider. Lots of other worthwhile suggestions I see too. Hopefully it's not a combination of things.

Let us know how it goes!
