Ideapad 5 Pro 16ACH charger state not correctly recognized

Support

Hi,

I have an ideapad 5 pro with the ryzen 5800h and GTX1650.
It mostly works great with the latest linux, however I have found two issues related to the battery:

  1. The charger state is not recognized correctly. The icon shows the charger is connected even though it is not. First this only happend sometimes and could be seen as “delayed reaction” with some good will, right now it is permanently showing that it’s charging. However the charge percentage is shown correctly. Also in the system monitor, the chargin rate always shows a negative value no matter if the laptop is charging or not. However the absolute value seems plausible.
  2. TLP behaves strangely. I tried setting a maximum scaling frequency on battery of 2GHZ, however this resulted in the CPU frequency being capped at 1.2GHZ (I suppose the lowest possible value). This limit kept active when I plugged in the charger or even removed the config and ran tlp start. Only a reboot with this limit removed restored the old config. However it was not necessary to reboot the laptop for the limit to get activated. Interestingly, the tlp start command returns the correct charger connection status even when the icon does not.

Here is my system info:

Using the 5.15 kernel does not help.
Any ideas how to fix this?

What about kernel 5.10 ?

3

Try booting Manjaro Gnome or Cinnamon ISO and see if the charge state issue still exists.

4

Not able to help, but I have exactly the same issue on my IdeaPad 5 Pro. I have the R5-5600h with RTX3050. For me I first noticed this issue yesterday, but have been on 5.15 kernel for a little while now.

I know it’s not a structural fix, but let the battery drain completely until the laptop powers off. After doing that, and then fully charging, the status has reset and everything is good again.
