[Bug 1912935] Re: battery drain while notebook off / shutdown

I'd like to find out which power resource needs to be turn off.
Can you please find out which module needs to be unload before shutdown can avoid the battery drain?

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.

Same power consumption on 20.10 (Groovy Gorilla).
