Lenovo not charging

[CcHhDdOo]

Hi guys,

I just tried tlp for my Lenovo, but now it's not charging anymore. I guess I have the wrong driver. I could use some help please.

Uninstall TLP. Shut down the laptop. Switch it on and start. Is it now charging the battery?

[CcHhDdOo]

I did all the mentioned things already.The thing I didn't do was letting drain the battery as I hoped for a battery reset or so. In fact at under 30 % the cpu automatically reduced so I plugged in again and it's charging now. Let's see how far.

[CcHhDdOo]

Battery stops charging at 60 % like it did before. So the problem still is that I can't go beyond that value (battery charge thresholds not available). Maybe before I switched to Linux, the Windows App Lenovo Vantage had battery protection as active and is now keeping this setting although having Linux now.

[linrunner]

Since "laptop not supported" is displayed, it is very unlikely that TLP has set the charge threshold.

Apparently Mint has loaded the wrong vendor specific driver, asus_wmi instead of ideapad_laptop. Let's fix it manually. Please show the output of:

sudo modprobe -rv asus_wmi
sudo modprobe -v ideapad_laptop
sudo tlp-stat --cdiff -s -b

[CcHhDdOo]

I've found the solution: There is that Vantage App also for Linux https://github.com/niizam/vantage

There I can turn off the conservation mode and now it's charging beyond 60 % again, yeah!

Anyway, thank you for the support.

[linrunner]

@CcHhDdOo I am (on behalf of other Lenovo users) very interested to know if setting the threshold also works with TLP when the correct kernel module is loaded. So I would be grateful if you could show the outputs.

[CcHhDdOo]

It looks like there is only on (1) or off (0) for the threshold, which is preset to 60% :

[linrunner]

The output of the two modprobe commands would have been important, do you still have them?

[CcHhDdOo]

lenovo@Lenovo:~$ sudo modprobe -rv asus_wmi
rmmod asus_wmi
rmmod battery
lenovo@Lenovo:~$ sudo modprobe -v ideapad_laptop
lenovo@Lenovo:~$ sudo tlp-stat --cdiff -s -b

[linrunner]

So you have to blacklist asus_wmi. I will write this in the FAQ. Thanks.

[linrunner]

I changed the vendor detection sequence. Should work without blacklisting now.
