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’ve had a similar issue with most of the laptops I have owned. The battery just discharges slowly when the device is turned off.
I have no idea what causes it or if it can be fixed.
Same for me with a MSI laptop, no solution
Same with my Lenovo, not in few days tho but maybe in week or a two.
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.
I checked and yes, there’s no cmos battery in it. Do you think this may have something to do with it?
do you have any usb devices, like external hard drives, chargers or similar connected to it? a lot of the laptops allows for usb charging/supply of power even when switched off, and this could be one of the sources for the drainage.
try disconnecting all USB cables if any are connected and see if the problem disappears?
never mind, did not see the line about no connected usb cables until after posting
