AI 300 (HX 370) strange PD charging behavior on both Windows and Linux

Hi,

My guess is that you might be seeing some of the problems experienced by others of on this thread:

[TRACKING] Battery flipping between charging and discharging / Draws from battery even on AC

With AC connected and battery charge at the set threshold, the battery status as reported by the kernel often flips between charging and discharging, sometimes even within one or two seconds. (This can be seen using the Gnome battery icon or upower -d). AC is always reported as online. This also means I get a constant stream of udev events starting tlp, which then notices that AC is still online and does nothing, but this could probably be solved by tweaking udev rules. Some more observations: …

Sometimes, the command “sudo ectool chargecontrol idle” helps. But the real fix is better EC firmware.
