Hello. I would just like to mention that I, too, face this same exact issue. I'm running Manjaro and can confirm that I observe this issue on both Linux 5.10.70-1 and Linux 5.13.9-2. After a full week of testing I can confirm that I face this power drain only when gracefully shutting down from Linux.
Basic hardware specs: OS: Manjaro Linux x86_64 Host: HP Pavilion Laptop 15-cc1xx Kernel: 5.10.70-1-MANJARO Resolution: 1920x1080 DE: Plasma 5.22.5 WM: KWin CPU: Intel i7-8550U (8) @ 4.000GHz GPU: Intel UHD Graphics 620 GPU: NVIDIA GeForce 940MX Bios: InsydeH20 f.36 Rev 5 Some timings I've recorded: - 44% drain in 9h20m - 36% drain in 6h48m - 32% drain in 5h35m When sifting through the system logs using journalctl I didn't find anything that stuck out as unusually suspicious. No errors as far as I can tell - but honestly, I don't know enough about Linux to be 100% sure so please don't hold me to this. I can attach these logs if needed. Commands used: - journalctl -b -1 -r - journalctl /sbin/init -b -1 -r | grep -i shutdown - journalctl /sbin/init -b -1 -p err..alert Like asgard2 I can confirm that I do not have wake-on-lan enabled (my system doesn't support it in the first place as confirmed by the lack of an option in my UEFI menu and no indication from ethtool), no usb ports providing power when shutdown, no noticible power drain when shutting down from the UEFI menu or from Windows, etc. basically everything they have reported above. I'd love to help get this fixed - if I can help out by providing more data, please let me know. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1912935 Title: battery drain while notebook off / shutdown Status in linux package in Ubuntu: Confirmed Bug description: Hello, my battery drains around 15 to 20 percent a day when shutdown on linux ubuntu. It is an HP notebook HP 15s-eq0355ng , Ryzen 5 3500U , Vega8 . Tested: - with ubuntu 20.04 - Kernel 5.4, 5.8 (hwe) and the current mainline kernel 5.11 (rc4) - no usb devices are plugged in - no wake ob lan available - no USB power when off (checked with optical mouse) - no visible LEDs are on when shutdown I reinstalled window 10, when shutdown from windows there is no (visible) battery drain (or significantly lower). Linux is unusable on this device, if the battery drains in a short time to 0% percent. This cause battery damage ... --- Tested TLP with default settings and activated DEVICES_TO_DISABLE_ON_SHUTDOWN (bluetooth wifi wwan), same power consumption after shutdown.
